MAIN FUNCTION
The system features a combined inertial/satellite navigation mode as well as a pure inertial mode.
In the integrated inertial/satellite navigation mode, the GNSS receiver captures satellite positioning information which can be utilized for integrated navigation. This mode outputs carrier pitch, roll, heading, position, speed, and time information. In the event of a signal loss, the inertia-calculated position, velocity and attitude are output. The pitch and roll require precise calibration with a short-term course holding function and can achieve meter-level positioning accuracy within a short time.
The pure inertial mode (that is, GPS fusion has never been carried out after power-on, and if it loses lock again after fusion, it belongs to integrated navigation mode) possesses an accurate attitude measurement function and can output pitch, roll, and heading. Pure inertia can perform static north searching.
