Login - Google Maps APRS

This is a global APRS database, which archives position tracking, weather and message information collected from the APRS-IS network. Position data and routes traveled by APRS tracking stations are shown on an interactive map which can be zoomed and panned easily. New and updated data is shown on the map in real time without need to reload or refresh the page! Tracking data is stored in the database for six months.

Please enter your callsign, first name or nickname here to view the map. It will be used for statistical purposes and guessing an initial map view - if the entered callsign is transmitting APRS position reports, the map will be centered on that location. If you are worried about your privacy, please enter something else.

You can also use this service to find your QTH/QRA locator (or your grid square) by simply pointing at a location on the map. Entering a QTH locator in the search box will move the map to the given location and show a rectangle containing the given locator. Short and extended locators are supported (from KP20 to KP20LE20TP).

This service should work with the same browsers as the Google Maps site, although development and testing is only done using MSIE and FireFox. Safari and Konqueror are known to work, too. If you are experiencing problems with one of the supported browsers, please check Google's troubleshooting guidelines. The service uses JavaScript and cookies extensively, and requires considerable horsepower from the client computer to work smoothly with a large amount of waypoints on the map. If it feels too slow, try removing target types from view (see options), zooming in or reducing the size of the browser window.

This page shows real-time information collected from the Automatic Position Reporting System Internet network (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 it's 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. 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.
