The LabSat 3 Turntable Replay system can be placed in any test location like a test laboratory or facility.

The system comprises of:

  • LabSat 3 Replay Only or Record & Replay system. The LabSat 3 will replay scenario files with GPS, GLONASS and BeiDou signals. Use either CAN data or electronic wheel speed pulses to replay the forward speed of the platform. The LabSat 3 will replay the data accurately synchronised with the GNSS data into the device under test (DUT).


  • Video VBOX data recorder, can be used to record the performance of the display screen of the navigation system being tested (DUT). This video recording can be replayed alongside previous video recordings of test replays to provide a functional visual comparison.


  • Turntable and controller used to turn the DUT in sync with the GNSS replay and the wheel speed information.


  • PC with LabSat 3 Extensions Software to replay the yaw to the turntable and to sync and replay the recorded video.
