Research on Strap-down Inertial Navigation System Simulation

In order to the features of inertial navigation, the simulation of strap down inertial navigation system is divided into four parts: flight track simulation module, gyroscope simulation module, accelerometer simulation module and Strap-down inertial navigation algorithm module. Using Simulink/Aerosim simulation toolkit for simulation of various modules, and ultimately get the position error, proved the correctness of simulation model. The signal of navigation parameters will be loaded into the physical model through the interface, after the format conversion of electrical characteristics of binding and the formation of ARINC429 signal.
