Aprs.fi user guide
This is the official manual for the aprs.fi web service.
Introduction
The aprs.fi web service collects information from the Automatic Packet (or Position) Reporting System Internet System (APRS-IS). APRS is used by amateur (ham) radio operators to transmit real-time position information, weather data, telemetry and messages over the radio. A vehicle equipped with a GPS receiver, a VHF transmitter or HF transceiver and a small computer device called a tracker transmits its location, speed and course in a small data packet, which is then received by a nearby iGate receiving site which forwards the packet on the Internet. Packets are also retransmitted on the radio channel by digipeaters to enhance the coverage of the system. Systems connected to the Internet can send information on the APRS-IS without a radio transmitter, or collect and display information transmitted anywhere in the world.
In addition to that, aprs.fi also displays AIS data transmitted by most large ships. AIS transmissions are received by volunteers at numerous sites, but most areas are largely uncovered.
This guide aims to become a comprehensive manual for the aprs.fi web site, and as such does not attempt to describe the APRS or AIS systems in detail. To get started with APRS, please consult the following pages:
AIS is described well on the Wikipedia page for Automatic Identification System.
Languages and localisation
The aprs.fi service has been translated by volunteer users to numerous different languages. The language shown to you will be selected based on your browser’s language preference settings. If you wish to preview the site in different languages, please prepend the two-letter language code to the site URL, for example:
- http://fi.aprs.fi/ – aprs.fi in Finnish
- http://ja.aprs.fi/ – aprs.fi in Japanese
- http://en.aprs.fi/ – aprs.fi in English
The site also supports different measurement units (metric, imperial and nautical), which can be selected in the preferences.
Site navigation links
Each page has a set of navigation links at the top of the page, and another at the bottom. On the real-time map, the links are provided in the navigation bar at the right side of the map, which can be hidden by clicking the button in the top right corner of the page.
The general idea is that the links on the top provide links to different data views. If you have already looked up a specific station, the links will contain that callsign, and clicking on the weather link when viewing the info page of a weather station will give you that station’s weather history graphs.
The links at the bottom page provide links to static content pages such as the FAQ and this user guide, which give general information about the whole site.
There are a few exceptions to these rules, of course – the My account and Moving stations links, for example.

Discussion group, blog and other points of communication
If you have any questions, answers, ideas, tips or tricks, please share them on the official aprs.fi Google Group. It’s available as a web-based forum and as a regular mailing list. Before posting, please read the instructions on the forum’s front page, especially the requirement for as many relevant details as possible (including exact callsigns and page links in question). The forum exists strictly for discussing the aprs.fi web service – please use the other relevant forums for discussion about generic APRS issues or tracker configuration problems.
Please read through the Troubleshooting section before posting to the discussion group about any problems. Thank you!
News about the aprs.fi service are posted on the aprs.fi blog, which can also be subscribed over email, or using an RSS reader. Headlines from the blog are shown regularly in the lower right corner of the real-time map.
News items, even the smaller ones, get posted on the aprs.fi Twitter account.

aprs.fi user accounts
This section of the aprs.fi user guide describes aprs.fi user accounts and common tasks related to them.
An user account is needed to use some specific functions of this web service. It is not needed for viewing any of the site contents, but when you wish to upload something to the site or use the API, the site needs a way to identify you and associate you with the uploaded data.
Creating an user account
Sign up for an account using your email address.
Please do not reuse passwords. When aprs.fi asks you to choose a new password, please pick a new one that you only use on aprs.fi. aprs.fi does not need to know the password you use for email or banking.
If you’re a licensed amateur radio operator, enter your plain callsign in the callsign field, without any SSID (-9, -14). SSIDs are entered later when setting up web stations, if necessary.
After filling up the form, aprs.fi will send you an email containing a unique link which you’ll need to click to activate the account. This procedure confirms that you have access to that email address. The email should normally appear in your inbox in a few minutes – if it doesn’t, please check your Junk / Spam folder. Sometimes spam filters have their false positives.
Forgot the password?
Use the reset password feature.
Resetting the password is only possible if you can read email at the address you’ve previously used when signing up. If you no longer have access to that email, simply create a new account.
Changing the callsign or nickname
You can edit the callsign in the My account view.
If you have created web stations and uploaded positions already, you can edit those stations to have the new callsign in the My stations view, under the My web stations heading.
Changing your email address
Unfortunately aprs.fi does not support changing the email address associated with the account quite yet. Please create a new user account using the new address, and delete the previous one in the My account view.
Aprs.fi Real-time map
Real-time map
The real-time map which opens up first when you arrive on the site displays, in nearly real time, APRS and AIS data on top of maps or satellite images provided by Google Maps. By default, it opens up showing the real-time situation in an area which should be relatively near your current location. The location guess is based on your IP address and it is a bit rough, but usually it opens up at least in the correct country. It is possible to select and save an initial view, but more on that later.
On the left side of the map you’ll find the familiar Google Maps map controls which can be used to zoom and pan around the map. You can also use the mouse to drag the map, and the wheel of a mouse (if you have one) to zoom.
On the top of the map there is a box showing the coordinates and locator currently under the mouse pointer, a controls to switch between different map layers (street map, terrain map, satellite images and hybrid satellite+street map), and a control to enable additional layers on top of the map (traffic info, bicycle routes, and so forth).
On the right side of the map is a menu area containing the search boxes, links to switch views, links to information pages, and possibly some advertisements or links to news about the aprs.fi site. Near the bottom, right above the advertisement is a small status box which indicates the rather frequent updates of the real-time map data. The updates normally happen once every few seconds.
Clicking on any of the ship or vehicle symbols will open up an info balloon showing current information on that tracking target.
Station name label colors
The callsign / name labels shown on the map have colors which mostly match the APRS symbol attribute colors in Bob Bruninga’s original APRS software.
- White: APRS stations which are capable of messaging
- Gray: APRS stations which are not capable of messaging
- Violet: Objects
- Purple: Items
- Green: AIS stations
- Yellow: Weather stations
Controlling the amount of data displayed
Near the top right corner there is a drop-down selection for the amount of history shown. When looking at the real-time view of an area (and not tracking a station), the maximum setting is 24 hours. Beware – if you’re looking at a busy area, or have zoomed out to see a lot of APRS stations, selecting 24 hours will likely make your browser slow down to a halt, just because it needs to display so many symbol graphics and path lines.
If you’re tracking a single target, the maximum selection is 7 days.
If you’re having trouble with the map being too slow, or the browser freezing, please take a look at the troubleshooting section.
Searching for an APRS callsign or AIS vessel
The first input field in the top right corner of the page, labelled Track callsign is used for looking up a specific station by it’s amateur radio callsign. Ships can be looked up by either their names (which are not always unique) or by their unique MMSI numbers (think of it as a phone number for the ship). Enter the callsign of the station in the box and click on Search. The most recent known position of that transmitter will be shown. For example:
(Please right-click the link and select Open in new window or new tab to avoid navigating away from this page.)
After looking up the station, no other stations in the area will be shown. You can bring other stations into view by clicking on Show all, while still tracking the selected station. If the tracked station moves, the map will center on the new position.
To stop tracking stations, click on Clear. This will reset the page to a real-time view at the same location and zoom level.
Looking up multiple targets at the same time
It’s possible to search for multiple targets at once by separating the callsigns or names with commas:
SSIDs – identifying multiple stations owned by the same operator
More often than not, a single amateur radio operator has multiple stations: one at home, one in the car, and maybe a hand-held walkie-talkie too. These are identified by their SSID (Secondary System Identifier) numbers, which range from 1 to 15. OH7LZB could be the home station, OH7LZB-9 is probably the car, and OH7LZB-14 could be a motorcycle. After you have successfully looked up one of these, links to the other available SSIDs for that station are shown below the search boxes. The ones which have recently transmitted their position are shown with a larger font.
Searching for an address
The second input field on the right searches for an address, a city, or a QTH locator. Given a specific address it will center the map at that address. Example searches:
- Kuopio
- searches for the city of Kuopio in Finland.
- Paris
- searches for the city of Paris. It is quite likely to jump to Paris, the capital city of France, but if you are located in the USA, it might as well come up with the city of Paris in Illinois, USA. Many city and town names are not unique!
- Paris, IL, USA
- searches for Paris in the state of Illinois, USA.
- Paris, France
- searches for Paris in France.
- Paris, FI
- searches for a Paris in Finland, and manages to find Pariisinkatu (Paris Street) in Helsinki.
Enter the components of the address from the most specific to the least specific, separating them by comma characters. For example:
In other countries and languages, use whatever addressing system is typically used. Google understands many languages. As an example, here is the Japanese address for the Kyoto tower. Zoom in and switch to the satellite view:
The address lookup service is provided by Google Maps, and functions similarly to maps.google.com. In other words, if it doesn’t find something, it’s Google’s fault.
Coordinate search
You can also enter coordinates in the address search box in several different formats:
QRA locator search
Given a Maidenhead / QRA / QTH locator aprs.fi will center on the locator’s middle point and draw a rectangle around the locator’s borders. For example:
You can also check the coordinates and locator of a position on the map by simply pointing at the position with your mouse and reading the coordinates from the box in top left corner of the map.
Looking up historical data
To view past positions of a station, first look up the current position. A date browsing menu will appear on the right, consisting of the years for which data is available on aprs.fi. First, click on the year, then select the month, and finally, select the day you wish to view. The menus might open up a bit slowly at first, since aprs.fi needs to consult it’s huge historical database to check the availability of data for the station in question.
aprs.fi normally stores position history data for about a year. If you wish to retain your tracks for a longer time, please use the Data export tool to download a KMZ file for offline viewing using Google Earth.
The position history database only stores unique new positions of a station, together with start and end timestamps. The date browsing menu only displays days with new positions, so that you can easily pick from the days where there is something to be seen. When looking at a station which never moves, the date browsing menu should not find too many days with movement, unless the station is using a GPS which will usually give some bad positions every now and then. Fixed stations should use fixed coordinates instead of a GPS.
Tool buttons
In the top right corner of the real-time map you’ll see a set of buttons. These are used for controlling different tools on the real-time map.
The hide button hides and displays the menu bar on the right, effectively switching to a full-screen mode of a sort.
The home button jumps back to your initial view, which might be a very rough guess of your location, or a specific view configured by yourself.
The PHG button toggles between no PHG circles shown, half-size PHG circles and full-size circles. The PHG circles display estimated service areas of APRS digipeaters and igates. They are very rough estimates or guesses made by the operator of each digipeater and usually they are not based on any exact statistical measurements.
The center button requests your current location from your web browser and centers the map on that location. The browser needs to support the Geolocation API for this to work, and for accurate positioning a GPS device is needed. This works especially well on new mobile devices such as the iPhone, iPad and Android-based phones.
The share location tool requests your current location from your web browser and shares it on aprs.fi. Like the center button, this requires Geolocation API support, but you also need to create an user account on aprs.fi and log in using the user account. Please be aware of the privacy implications of uploading your location on the Internet. While the information can be deleted from aprs.fi on the My stations page, it is often sometimes close to impossible to remove something from the Internet, since others might have already downloaded the information and uploaded it to numerous other places on the net.
The my stations and bookmarks button displays a list of your favourite stations and bookmarks on aprs.fi. The list can be used to quickly recall those stations and map views. The favourites list is stored on the aprs.fi servers together with your user account, so you need to be logged in for it to work. The favourites list can be edited on the My stations page.
The ruler button enables the ruler tool, which can be used to measure distances and bearings on the map. After clicking on the tool button, click somewhere on the map, and a marker will appear. Use the mouse to drag the marker to another position on the map. Another marker will appear from below the first one, a line connecting the two will be shown, together with the distance and bearing from point A to point B. You can also click the markers to see the exact coordinates of the marker. Multiple rulers may be placed on the map at the same time, just click on the button again to start from the beginning!
Selecting an initial default view
You can save the current map view, including the map type, zoom level and tracking settings, so that they will be recalled when you next open up aprs.fi. It’s a good idea to do this especially if the initial guessed location is far off from your area of interest.
- Click on Preferences to open up the settings window. It’s under the Other views title.
- The first item in view is Save current map view as default view. Check the checkbox.
- Click on Save at the bottom of the page.
The preferences are stored in your browser’s cookies, so they will not apply when you open up aprs.fi on another computer or using another browser. You do not need to have an user account aprs.fi to save the preferences. The rest of the settings in the Preferences dialog are described in the Preferences section of the document.
Street View
Google’s Street View has been integrated in aprs.fi, allowing you to view street-view panoramic photos on the site.
You can open Street View by dragging the yellow pegman (from above the zoom control) to the map. When dragging the pegman, a yellow overlay will indicate the roads with panorama photos. Drop the pegman on a road and the panorama will open. You can drag the panorama to look around, and click on the arrows to advance along the streets.
If you click on Track in Street View in the info balloon of a station, the panorama which is closest to the current location of the station will be opened. You can also click on any red track point along the path of a station to jump there (or any other station, for that matter). When a currently tracked station moves, the Street View jumps to the new position automatically.
If the clicked station is transmitting a course (which generally requires that the station is moving), the Street View will open up pointing to that direction. If the station is not transmitting a course, the camera will point from the panorama picture’s center coordinates (where Google’s camera was when the panorama was taken) to the exact coordinates transmitted by the stations. This implies that clicking on a house symbol of someone’s home station will often open up a photo of that house (with antennas on top).
If no panorama photos are available for the required position, the Street View will close automatically. Unfortunately no error message is shown at this point – better feedback for Street View errors will be implemented later.
For more information on Street View, please consult Google’s Street View documentation.
Packet path lines
When you bring the mouse cursor on top of an APRS station or a red track point, a line indicating the packet’s known path over the APRS network is drawn. The line should traverse via the digipeaters and end up at the igate listed in the packet’s path. If you are not tracking a station, the line will only be drawn via digipeaters and igates which are visible (or just outside the visible area). When you track a station, the used digipeaters are loaded on the map even if they are outside the visible area.
The path taken by that position packet is shown in the info balloon. In this case, the packet’s destination callsign was APZMDR, it went through the digipeater OH7RDA, was transmitted with an original path of TRACE2-2 (requesting two digipeater hops) and received by the igate OH7AA.
If the first receiver of the packet can be positively identified, the line leading to it will be green. The last line leading to the iGate will be purple. Other line segments are blue.
There are a lot of digipeaters in the network which still do not add their callsign to the path when retransmitting the packet. Because of this the path display is often incorrect and shows some incredibly long hops.
Ambiguous positions
Many APRS transmitters using MIC-E or uncompressed packets can be configured to intentionally transmit less precise positions. This may seem a bit backward at first, but there are perfectly good reasons to do so. Some people might want to transmit a rough location of their car without revealing the exact parking spot where their expensive radio gear spend their night in. Some might like some aspects of APRS but wish to adjust the level of privacy by hiding their precise location.
Ambiguity is configured by setting the number of digits which will be truncated from the end of the position. Plaintext APRS positions are transmitted in degrees and decimal minutes (DD° MM.mm’), with two decimals of minutes. When ambiguity is set to 1, it’ll be truncated to DD° MM.m’, 2 will transmit DD° mm’, 4 will transmit DD° only, resulting in a resolution of 1 degree.
The station in the following image has chosen to send positions with 1 digit of precision reduced. It can be seen that the car is driving the ring road, but the positions are slightly off.
Stations transmitting ambiguous positions are shown on the real-time map with a purple dashed border around the callsign label. The precision of the position can be visualized by hovering the mouse pointer on top of the station symbol – a purple rectangle will pop up, showing the area of ambiguity. The station symbol is drawn at a slightly randomized position within that area. Also, the station’s info page will say something along the lines of “Position ambiguous: Precision reduced at transmitter by 3 digits, position resolution approximately 18.5 km.”
Map context menu
Clicking the right mouse button on the real-time map opens up a context menu, which can be used to trigger actions specific to that location. On a Mac, press the trackpad with two fingers.
Center map here
Centers the view on the specified location.
Upload my position
Publishes your current position as being below the mouse pointer. The default web station gets moved to this location and will show up on the real-time map for other users.
Add marker
Creates a new temporary marker, which can be moved (drag-and-drop). The markers can be used to temporary mark locations and initiate further actions on those locations, such as creating labelled links. The markers will be forgotten as soon as you navigate away from the real-time map. Multiple temporary markers may be created at a time.
Clicking on the marker opens up an info balloon, displaying the coordinates for the marker, and the action links.
Clicking on Link to this position generates a link with the coordinates, which can then be sent over an email or IM conversation. Clicking on the link will open up the map at those coordinates, showing a marker on the specified position. You can also add a descriptive label in the link by typing it in the provided input field. The label will be shown in an info balloon when the link is clicked. For example:
Keyboard shortcuts
- Arrow keys – pan the map
- Page up, Page down, Home, End – pan the map quicker, one page at a time
- +, – – zoom in/out

Aprs.fi Troubleshooting
This section of the aprs.fi user guide goes through common problems.
My position is not showing up on aprs.fi
If your APRS position is not showing up on the site, the most common problem is incorrect symbol setting in the tracker. Please check the raw packets to see the error messages (enter your callsign and click on Search). If you have a problem with the symbols, please check the APRS symbol configuration page on the APRS Wiki.
You should also check if your positions show up on other sites such as DB0ANF and findu.com. If the positions are not showing up on the other sites, the problem is most likely in your tracker’s configuration or the local APRS network (or lack of it). Please get in touch with either another local APRS user, or your tracker’s user group. Many of them are listed on the google group’s front page.
If the positions are showing up on other sites but not aprs.fi, please check the raw packets again. aprs.fi is sometimes a little bit stricter than others about the packet syntax correctness, especially when it comes to symbol settings, and might reject a broken packet which others digest happily. Sorry about that.
My vehicle’s position is jumping back and forth to old positions
This can happen due to many reasons, including:
- Your tracker transmitting packets very often, increasing the chance that they arrive at aprs.fi in the wrong order
- Your tracker transmitting packets with a very long digipeater path, increasing the chance that they arrive out-of-order
- A dysfunctional digipeater buffering packets for a long time before retransmitting them
- An igate with a bad Internet connection buffering packets before getting them on the APRS-IS
- A broken digipeater or igate mangling the contents of packets, so that the duplicate packet looks a little bit different than the original and won’t be detected by the duplicate detection algorithms
The first two are easy to fix. The second two are harder to track down, but their effects can sometimes be mitigated by reducing the transmitting rate and using a shorter path, so that the packets do not go to a faraway broken digipeater.
aprs.fi tries hard to filter old positions, but sometimes they still get through. Because APRS packets do not contain sequence numbers and usually do not contain timestamps, it’s hard or impossible to properly catch the duplicates.
There is a long blog post describing issues with duplicate and delayed APRS packets on the aprs.fi blog.
The real-time map does not show
This application makes heavy use of Javascript and Cookies. Make sure your browser allows aprs.fi to use both. If it asked for permission to use these when you first arrived on the site, and you didn’t allow it at that time, the selection was probably stored in your browser’s configuration, and you’ll need to go to the security preferences menu to change that.
The page layout looks funny or strange
At my workplace, there are sometimes problems with the web proxy server, and the CSS files defining the style and layout fail to load, resulting in a broken layout. This can be cured by doing a “power reload” by pressing CTRL and clicking the reload button (on IE). On Firefox, it’s SHIFT-reload, and on Mac Firefox, you need to keep the Apple (Command) key down while clicking the reload button. Alternatively, you can try clearing the browser’s cache (temporary files).
If this doesn’t help, you’re probably running a very old web browser (such as Internet Explorer 6, 7, 8). The old browsers are quite badly broken, and it would take an awful lot of time for me to make the site work with them. New browsers just work.
If you’re running a modern browser and still see layout problems (or any other problems), please let me know through the google group.
The real-time map is slow
The map is quite heavy for the browser, especially when a lot of symbol graphics and track lines are visible at the same time. This application is simply quite complicated and heavy for being “just a web page”. It is very hard to make this run smoothly on a slow computer. The aprs.fi servers are quite fast and optimised for the task, and the slowness happens generally only due to the slowness of the browser’s Javascript engine.
If possible, try out another browser. Google Chrome and Apple Safari have much faster Javascript engines than Internet Explorer and Firefox. New Internet Explorer versions (IE10 and later) are faster than the older ones.
The map is faster when there are fewer markers visible – just try zooming in a bit. In Preferences => Filtering you can hide some target types you’re not interested in. Selecting Show with track instead of Track + waypoints will hide the small red dots indicating transmitted positions along the track, which will reduce the amount of markers and might give a considerable speed-up.

Garrett Down KD6KPC of Repeaterbook.com shared this if you want to donate to his website:
To run a website like Repeaterbook.com, revenue is needed to keep it active on the web. There are bills to be paid, hosting companies to be paid, SSL certificates to be purchased, and other expenses that go along with the research and development of the data. The costs add up.
Repeaterbook has committed to keeping access to its data completely free. Since we don’t charge for the data or access to the site, we decided to incorporate ads into the site. The ads generate revenue that has been sufficient to pay the bills (most months). With the advent of ad-blocking technology, we began to see ad revenue slip. We get it. Many people don’t want to see ads and our stats indicate that up to 30% of our site visitors are using an ad blocker. Some say the performance on the site has even suffered waiting for ads to load. And come are concerned about Internet tracking through the ads (yes, Google does it).
We think we have found a solution to meet in the middle.
You can now subscribe to Repeaterbook and obtain a membership that will silence the ads on Repeaterbook. This form of obtaining revenue while quieting ads is used on qrz.com.
So now we have two option to fit your preference:
- Enjoy Repeaterbook completely free, while enduring the ads that appear.
- Sign up for a Repeaterbook subscription and silence the ads.
To take advantage of this offer, you must be a registered user in good standing. Look at our Subscription Plans:
