Fuses multi-constellation GNSS (GPS/BDS/GLONASS) raw data with 1000/s gyro, 2g accelerometer MEMS IMU for centimeter-level positioning (RTK <1cm+1ppm) and 0.2 heading stability.
Automatically switches to pure inertial mode when GNSS is lost, with position error growth rate <0.1m/h via IMU raw data and sensor fusion (barometer/magnetometer).
Processes 400Hz-1000Hz data with multi-sensor fusion (barometer, magnetometer, encoder) for <0.05m/s speed accuracy and low-frequency error suppression.
Factory-calibrated IMU (zero bias, scale factor, cross-coupling) and GNSS antenna lever arm compensation eliminate installation errors, ensuring <0.05 dynamic attitude stability.
EKF/UKF filters model position drift growth, with RTK <1cm+1ppm and pure inertial <0.1m/h growth rate, enabling long-duration high-precision navigation.
Integrates GNSS/IMU/barometer/magnetometer/encoder for anti-multipath, anti-occlusion, and anti-interference in urban canyons, water surfaces, and tunnels.
Dual-antenna baseline (0.8-1.5m) heading accuracy <0.2 via GNSS carrier phase difference, no magnetometer reliance.
Factory pre-calibrated IMU and on-site lever arm (X/Y/Z offsets) compensation eliminate installation errors, reducing output errors to <0.1.
Switches between tight EKF-coupled (RTK) and loose (pure inertial) modes, ensuring <0.1m/h position drift growth in GNSS-denied scenarios.

Product Q&A
Q:How does INS maintain position accuracy without GNSS input?
A:
In pure inertial mode, INS uses IMU raw data (angular velocity/acceleration) integrated over time to compute position, with errors growing linearly at <0.1m/h.
Q:What is the typical drift rate in pure inertial navigation?
A:
Position error grows at <0.1m/h for pure inertial mode, with velocity error <0.05m/s and angular error <0.05/h.
Q:How does GNSS/INS fusion improve navigation accuracy?
A:
Tight EKF fusion combines GNSS pseudorange/carrier phase with IMU data to correct IMU drift, reducing position error from 0.1m/h (inertial) to <1cm+1ppm (RTK).
Q:What causes position error to grow over time?
A:
IMU sensor drift, environmental interference (temperature, vibration), and uncompensated installation errors (lever arm/tilt) cause errors to propagate.
Q:How does INS calculate speed and position from raw IMU data?
A:
Integrates angular velocity (gyro) to get attitude, then uses acceleration (IMU) with double integration to compute velocity and position; EKF optimizes for noise and drift.
