High Precision Integrated INS SI-FINS90S-D09 Pure Inertial Index: Horizontal Alignment ≤0.006°(1σ), Azimuth Hold 0.01°/h (1σ), Attitude Hold 0.005°/h (1σ) For UAV & Vehicle Positioning
This product features a high-precision three-axis integrated fiber optic gyroscope, a high-precision quartz flexible accelerometer, and a mobile survey-grade multi-mode multi-frequency GNSS receiver with native Beidou support. Through advanced intelligent composite navigation algorithms and Kalman filtering, it is optimized for GNSS occlusion and multipath interference scenarios, enabling high-precision measurement of heading, attitude, velocity, and position for moving targets.
The system also has a variety of sensor interfaces, such as GNSS, odometer, DVL, and barometer, which can meet the requirements of long-term, high-precision, and high-reliability navigation in complex environments like urban canyons. It can be used for navigation and control in various platform systems.
