Product Description

High End GNSS Receiver MEMS Inertial Navigation System for Surveying and Mapping

 

Product Description

 

GI300C is a compact inertial navigation system with fiber optic gyroscope (FOG) and micro-electromechanical system (MEMS) accelerometers, which can use external GNSS accurate timing and positioning information for inertial/satellite integrated navigation. When the external GNSS information is invalid, the inertial navigation system has a high ability to maintain the accuracy of pure inertial navigation.

 

Main Application 

  • Drone
  • Rocket
  • Mobile measurement
  • Detection and measurement of ground, tunnel and other tracks
  • High precision stable platform

Main Function

  • Shaking base/moving base alignment function
  • Self-seeking north
  • Outer GNSS/atmosphere multi-information fusion integrated navigation
  • Longer time accuracy retention without external information assistance
  • Support users to customize on demand

Note:

① The alignment is valid;

② For airborne use, there is a turning maneuver before the airspeed combination, and the test takes the  flight speed of 150km/H as an example;

③ On-board conditions, need to be mobile;

④ Two-position alignment, the heading difference between the two positions is greater than 90 degrees
