| Abstract: | The difference of transfer alignment between the platform-platform system and strapdown-strapdown system is described in detail. Then the velocity error equations and the frame angle error equations between the master platform system and the slave platform system are deduced, and the mathematical models of the platform-platform system transfer alignment are set up, and the angle velocity and angle acceleration of the vehicle are obtained by two lowpass filters which can restrain effectively the high-frequency noise in the angle velocity and the angle acceleration respectively. The final simulation result shows that the slave inertial system’s misalignment can reach an anticipated precision of 0.15 degree in 120 seconds. |
