GAPS - User Guide
7.4 Coupling Using MTBx2 Acoustic Communication
MTB is GAPS compatible for tracking and telemetry. The MTB sends and receives data via
telemetry during the positioning cycle. This data can be packed into a service (e.g. update the
position of a vehicle INS) or as a robust acoustic communication channel from and to the
vehicle to monitor its operations. The MTB position is sent over the acoustic communication
every three recurrences. The sent position is not the latest one but two positions before.
Constraints and coupling details are to be found in the MTB user guide.
