GPS/IMU clock same period for deep integration

摘要

The navigation system inertial measurement unit, has the navigation computer, the GPS receiver and the clock controller. Inertial measurement unit the 1st clock and has the 1st switch, the navigation computer the 2nd clock and has the 2nd switch, the GPS receiver has the 3rd clock. The 1st and 2nd switch is controlled being the clock controller. Because of this, inertial measurement unit, in the navigation computer and the GPS receiver it can, use the 3rd clock or inertial measurement unit and the navigation computer and the GPS receiver in use the respective itself clock use the 2nd clock or in inertial measurement unit and the navigation computer.
