NAV40U Inertial Navigation System (INS)

NAV40U Inertial Navigation System (NAV40Ultra INS / NAV40U INS) is a dual antenna INS that integrates a three-axis gyroscope, three-axis accelerometer, three-axis magnetometer, GNSS receiving module, barometric altimeter, and other microsensors, along with a Drone Inertial Navigation System, to have an accurate estimate of the drone status. It uses the built-in improved extended Kalman filter (EKF) algorithm for information fusion, effectively reducing the impact of carrier maneuvers, vibration, ambient temperature and electromagnetic interference, and providing users with complete and reliable three-dimensional position, three-axis attitude, three-axis speed, three-axis acceleration and other information at up to 200Hz.

Application areas include UAVs, robots, marine areas, unmanned vehicles, unmanned ships, vehicles, and human posture measurement.

• High performance;
• Support RTCM and RTK
• Support dual antenna directionality
• Up to 200Hz navigation data update frequency
• Guaranteed accuracy over the full temperature range (-40°C-85°C)
• Support users’ customization of structure, size, and data format
