Product Description

Fiber optic GNSS integrated inertial navigation system gyroscope sensors Attitude

 

Product Description

 

The GI500-A0 fiber optic integrated navigation system is based on high-precision closed-loop fiber optic gyroscopes, accelerometers, and high-end GNSS receiving boards. It is implemented through multi-sensor fusion and navigation calculation algorithms, providing high-precision heading, velocity, and position information to the outside world, meeting the requirements of high-precision measurement and control.

 

Main application areas

 

Large scale unmanned aerial vehicle reference inertial navigation

Ship Compass

Self propelled artillery orientation

Vehicle positioning and orientation

High precision mobile measurement

High precision stable platform

 

Product features

 

The system has  inertial/satellite integrated navigation mode and pure inertial mode.

Inertial navigation has a built-in GNSS board. When GNSS is effective, inertial navigation can combine with GNSS for navigation and provide users with combined navigation parameters such as position, altitude, velocity, attitude, heading, acceleration, angular velocity, etc. At the same time, it outputs GNSS position, altitude, velocity, and other information.

When GNSS is ineffective, it can enter pure inertial mode (i.e. GPS fusion has never been performed after power on, and if the fusion is lost again, it belongs to integrated navigation mode). After activation, it has precise attitude measurement function, can output pitch and roll heading, and pure inertial can static seek north.
