It precisely synchronizes the incoming IMU data* with GPS time and sends them over the Ethernet port. The high bandwidth of the communication ports easily handles up to 400Hz of IMU data that are logged on customer-provided PC. The precisely time-tagged data can be used for real-time or in post-mission GPS/INS integration.

* An alternative use accomodates synchronization of odometer pulses.
