high-precision fiber optic INS
,integrated fiber-optic inertial navigation system
,fiber optic INS with azimuth hold
This high-performance integrated navigation system is equipped with high-precision three-axis integrated fiber optic gyroscopes, high-stability quartz flexure accelerometers, and a survey-grade multi-mode and multi-frequency GNSS receiver supporting independent Beidou navigation. Adopting advanced intelligent integrated navigation algorithms and optimized Kalman filtering technology, the system is specially optimized to tackle GNSS signal occlusion and multipath interference in complex scenarios. It enables high-precision real-time measurement of heading, attitude, velocity and position for all types of moving carriers.
- Fast and highly accurate initial heading and attitude initialization
- Stable real-time heading and attitude continuous output
- Built-in dual-mode GPS and Beidou satellite receiver
- Supports high-speed dynamic rapid alignment during movement
- Integrated INS/GNSS all-in-one design, compatible with IE data post-processing
- Adopts enhanced Kalman filtering algorithm for stronger anti-interference and higher data accuracy
- Outstanding resistance to electromagnetic interference and mechanical vibration
- Optional built-in vibration damping module for harsh operating environments
- Software upgradable to realize professional compass functions
The system is widely applied in high-precision navigation and stability control fields, covering vehicle-mounted navigation, airborne navigation and ship-borne navigation scenarios.
