Inertial/Satellite Research and Design of Integrated Navigation Simulation System

The inertial navigation system is a navigation system which combines the inertial navigation system and satellite navigation system through the data fusion technology. The inertial navigation system has the characteristics of strong autonomy and short term precision. The satellite navigation system is highly accurate and easy to be disturbed, and the combination of the two has greatly improved the performance of the navigation system when it is used alone. Firstly, this paper design carrier track flight simulator, and the inertia devices such as gyro and accelerometer simulation, and by the method of superposition error of satellite navigation system outputs position and velocity are simulated. Finally on this basis, the data fusion technology is added, and the simulation of the inertial/satellite navigation system is realized.
