Northfinder™/
GCAH-12C
Gyro compass
Real-time attitude and heading angles are output without GPS
Description
- Achieves a more compact size, higher durability, and lower cost compared to RLG and FOG products by adopting MEMS gyroscopes
- Automatically calculates attitude and heading based on inertial sensor outputs
- Provides real-time attitude and heading output even in environments where GNSS is unavailable
Application
- Inertial Navigation System for Aerospace and Maritime vehicle
- Autonomous control for Railway, Automotive and Civil Construction
- Down Hole Surveying and Mapping
