Product Description

 Fiber Optic GNSS Integrated Inertial Navigation System for High-Precision Measurement and Control

Product Description

GI500-A0 (B0) fiber-optic integrated navigation system (referred to as "inertial navigation") is based on high-precision closed-loop fiber-optic gyroscope, accelerometer and high-end GNSS receiving board, and is realized through multi-sensor fusion and navigation calculation algorithm. It provides high-precision attitude, speed, position and other information to meet the requirements of high-precision measurement and control. Its main application fields include:

• Large UAV Reference Inertial Navigation System
• Marine compass
• Self-propelled gun orientation
• Vehicle positioning and orientation
• High-precision mobile measurement
• High precision stable platform

The GI500-A0 (B0) optical fiber integrated navigation system is divided into two configurations, GI500-A0 (B0) A0 and GI500-A0 (B0) B0. The electrical, structure and interface are completely the same, but the accuracy is different.

Main Functions

• The system has inertial/satellite integrated navigation mode and pure inertial mode.
   
• The inertial navigation system has a built-in GNSS board. When the GNSS is valid, the inertial navigation system can perform integrated navigation with the GNSS, and provide the user with navigation parameters such as the combined position, altitude, speed, attitude, heading, acceleration, and angular velocity, and output information such as the GNSS position, altitude, and speed.
   
• When the GNSS is invalid, it can enter 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 the integrated navigation mode). After starting, it has accurate attitude measurement function, can output the pitch and roll course, and the pure inertia can find the north statically.
