Compact Size FOG Inertial Navigation System For Vehicle Navigation And Positioning SI-FINS70SA
This product is built with high-precision three-axis single-fiber gyroscopes, high-precision quartz flexible accelerometers, and a mobile mapping-grade multi-mode and multi-frequency GNSS receiver supporting independent Beidou functions. Through advanced intelligent integrated navigation algorithms and Kalman filtering, and optimized design for GNSS occlusion and multipath interference, it can achieve high-precision measurement of heading, attitude, speed, and position of moving carriers.
This inertial navigation system has a variety of sensor interfaces such as GNSS/odometer/DVL/barometric altimeter, which can well meet the needs of long-time, high-precision and high-reliability navigation applications in complex environments such as urban canyons, and can be used for the navigation and control of various unmanned systems.
