Tactical Grade High-Accuracy GNSS Inertial Navigation System for Vessel Tracking
Product Description
INS-100 is a high-precision integrated navigation system designed for demanding applications requiring exceptional accuracy and reliability. It is equipped with three self-developed 40-grade fiber optic gyroscopes, tthree-self MEMS accelerometers, and advanced GNSS modules. By leveraging multi-sensor fusion and sophisticated integrated navigation algorithms, the system delivers precise positioning and navigation even in complex and dynamic environments.
With its high reliability and strong environmental adaptability, the INS-100 is suitable for a wide range of applications, including autonomous driving, unmanned aerial vehicles (UAVs), geospatial surveying and mapping, marine compasses, stabilized platforms, electro-optical pods, and underwater vehicles. Its robust design ensures stable and accurate performance across diverse operational conditions, making it an ideal choice for industries requiring superior navigation and motion-sensing capabilities.
Main functions of the integrated navigation system are as follows:
- 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;
- The GPS information received from outside can be used to complete the integrated navigation function and output information such as angle, speed and position.
- After the satellite signal is lost, the inertial device output and the odometer input can be used to continue the navigation calculation;
- It can output high performance and high sampling rate gyro raw output and add raw data for stable platform control.
- The program and configuration parameters can be upgraded online through the serial port.
