MAIN FUNCTION
The system features both a combined inertial/satellite navigation mode and a pure inertial mode. In the inertial/satellite integrated navigation mode, the GNSS receiver is able to receive signals from satellites, providing positioning information for combined navigation. If the signal is lost, the system switches to an inertial solution for position, speed and attitude, delivering meter-level positioning accuracy in a short time.
Alternatively, the pure inertial mode provides accurate attitude measurement and can output pitch, roll and heading data. Additionally, it has the ability to statically seek north.
