Embodiment Construction
[0038] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0039] A kind of SINS / CNS deep integrated navigation system of the present invention, as figure 1 As shown, it includes a strapdown inertial navigation system 1, a celestial navigation system 2, an integrated navigation filter 3, and an inertial navigation attitude measurement information construction unit 4;
[0040] A strapdown inertial navigation system (SINS) 1 includes an inertial measurement unit (IMU) 101 and a navigation solving unit 102 . The inertial measurement unit 101 (IMU) measures the angular velocity and specific force of the carrier relative to the inertial space, and transmits the obtained carrier angular velocity and specific force information to the navigation calculation unit 102, and the navigation calculation unit 102 is based on the information transmitted by the inertial measurement unit 101. Real-time calculation of the posi...
