Theory of operation
The SAT method of communication is synchronized event based reporting. Event could be GPS
location, motion start and stop, PBC found and which one. Once it’s connected to car battery the
SAT spends most of its time in low power sleep mode. When an event happens, the SAT sends a
report to the base station. In order to avoid packet collisions and associated detection methods,
the system uses a synchronous protocol, that is, An SAT can transmit data only after receiving a
synchronization signal from the base station.
