INS-100 is a high-precision integrated navigation system. It is equipped with three self-developed 40 fiber optic gyroscopes,three-self MEMS accelerometers and GNSS modules, and realizes high-precision positioning and navigation in complex environments through multi-sensor fusion and integrated navigation algorithm. The product has high reliability and strong environmental adaptability. The products can be widely used in intelligent driving, UAV, surveying and mapping, marine compass, stable platform, photoelectric pod, underwater vehicle and other fields.
Main functions of the integrated navigation system are as follows:
1. The initial alignment function is completed by using the output of the inertial device, and the shaking base alignment and the moving alignment can be carried out;
2. The GPS information received from outside can be used to complete the integrated navigation function and output information such as angle, speed and position.
3. After the satellite signal is lost, the inertial device output and the odometer input can be used to continue the navigation calculation;
4. It can output high performance and high sampling rate gyro raw output and add raw data for stable platform control.
5. The program and configuration parameters can be upgraded online through the serial port.
