The VN-300 incorporates a wide assortment of inertial sensors, including a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, a barometric pressure sensor, and two 50-channel u-blox GPS modules.  Calibration coefficients are stored on the sensor and are fully temperature compensated in real-time onboard to ensure high accuracy measurements over the full operating temperature range, according to the company

By employing two separate GPS receivers and antennas, the VN-300 is design to enable accurate heading measurements without reliance on vehicle dynamics or magnetic sensors.
