Inertial System Navigation Sensor Precise Attitude Position Dynamic Measure
The system has inertial/satellite integrated navigation mode and pure inertial mode.
In the inertial/satellite integrated navigation mode, the satellite positioning information received by the external GNSS receiver can be used for integrated navigation, and the pitch, roll, course, position, speed, time and other information of the carrier can be output; After the signal is lost, the position, velocity and attitude calculated by inertia are output, in which the pitch and roll are required to be accurate, the course keeping function is available in a short time, and the meter-level positioning accuracy is available in a short time.
After the pure inertial mode (that is, GPS fusion has never been performed after power-on, and if it loses lock again after fusion, it belongs to the integrated navigation mode) is started, it has the function of accurate attitude measurement, can output the pitch and roll heading, and the pure inertial mode can find the north statically.

Size:
The integrated design scheme is adopted for the inertial measurement unit, and the system outline is shown in the figure below.
The overall dimension of the system is 92.0 mm × 92.0 mm × 81.0 mm (length × width × height).
a) Power supply and communication interface X1;
b) One end of a cable is connected to X1, and the other end is divided into a power supply red and black clip and three serial ports, which are COM1 ~ COM3, where COM1 is RS422, COM2 and COM3 are RS232. COM 1 can be used to send the working mode command;
