INS300E Integrated Navigation System


  • Built-in shock absorption module
  • Accurate parameter calibration
  • Full temperature compensation.

The INS300E integrated navigation system consists of a MEMS three-axis gyroscope, a three-axis accelerometer and a built-in GNSS receiver. The inertial sensor can meet the performance requirements under different conditions after full temperature calibration. The built-in processor realizes the fusion of inertial device and GNSS receiver data, which can provide rich navigation information data including carrier attitude, azimuth, position, speed, time information, angular rate and linear acceleration information. It has the advantages of small size, low power consumption, high reliability and stable performance. The product can be widely used in missile-borne, airborne, precision agriculture, unmanned vehicles, and mobile communication.
