APRS (Automatic Packet Reporting System) is an amateur-radio based system for realtime communication using digital packets sent over radio links. I present here, an implementation of an APRS iGate using the Raspberry-Pi. An APRS iGate is an Internet gateway that gates packets from the radio/RF side to the APRS-IS on the Internet (and vice-versa). The APRS-IS is an Internet based network that connects...
This application allows you to send your position and messages to the APRS-IS network from your Android Phone.
It will establish your position from the built in GPS (more accurate) or thru a mobile network (less accurate). You may also transmit at fixed position in case you use a tablet without GPS or mobile connection.
The application is in english, feel free to download it. This page however...
Amateur Radio Balloon crosses the Atlantic but but potentially dangerous for international flights.
Yesterday evening an amateur radio APRS balloon, call sign K6RPT-11, succeeded in its crossing of the United States and the Atlantic ocean.
Launched from California, the balloon transmitted on the APRS frequency of 144.390 MHz FM that is used in the Americas. It appears to have traveled south of Portugal...
