 GPS tracking devices have been linked to an Argos Platform Transmitter Terminal (PTT) enabling them to transmit data via the Argos System, a scientific satellite system which has been in use since 1978.Users can download their data directly from Argos via telnet and process the raw data to extract their transmitted information.Where satellite uplink fails due to antenna damage, it may be possible to intercept the underpowered transmission locally using a satellite uplink receiver.
