Embodiment Construction
[0040] The purpose of the present invention is to provide a full digital simulation system of GPS / SINS integrated navigation system. The simulation system can replace the actual GPS / SINS integrated navigation system to verify the influence of various software algorithms in integrated navigation on navigation accuracy and develop new algorithms; at the same time, these verified algorithms and new developed algorithms can be loaded It is applied in the actual GPS / SINS integrated navigation system; the present invention has an important guiding function and practical significance on how to improve the navigation accuracy of the low-cost GPS / SINS integrated navigation system. The present invention mainly completes the following functions:
[0041] 1. The trajectory generator provides the flight trajectory data required by the entire integrated navigation simulation system.
[0042] 2. The IMU emulator simulates the real output of the gyroscope and accelerometer.
[0043] 3. The ...
