SN-FINS70S Fiber Optic Inertial Navigation System
This product integrates a high-precision three-axis fiber optic Gyro, a high-precision quartz flexure Accelerator, and a multi-mode, multi-frequency GNSS receiver with autonomous BeiDou functionality for mobile survey-grade mapping. Through advanced intelligent sensor fusion algorithms and Kalman filtering, it is optimized to address issues such as GNSS signal blockage and multipath interference, enabling high-precision measurements of heading, attitude, velocity, and position for moving platforms.
The inertial navigation system also features various sensor interfaces, including GNSS, odometers, DVL (Doppler Velocity Log), and barometric altimeters, making it well-suited for long-duration, high-precision, and highly reliable navigation applications in complex environments like urban canyons. It can be used for navigation and control in various types of unmanned systems.
