I have a GPS tracking device which was designed for inventory management, currently I'm using a GSM module to transmit the telemetry data (latitude and longitude only) to the base station. The problem in using GSM is it is not suitable to work in remote locations.
Is it possible to use a QRP transmitter to send the same data to the base station?
Edit: The current system is capable of sending the whole NMEA data with an interval of 1 minute, but I want only the latitude and longitude. Geographically, my locality (Kerala) is roughly divided into three climatically distinct regions. These include the eastern highlands (rugged and cool mountainous terrain), the central midlands (rolling hills), and the western lowlands (coastal plains).
Since this is a hand held portable device and supposed to operate in remote areas, there may be obstacles in between the transmitter and receiver so Line of sight communication may not be possible.
