分析了平台平台系统传递对准技术与捷联捷联系统传递对准技术的差异，在此基础上，推导了平台平台传递对准中主、子惯导系统速度误差方程和框架角误差方程，建立了平台平台传递对准数学模型，给出了角速度与角加速度的获取方法，设计的低通滤波能够有效抑制角速度与角加速度中的高频噪声。仿真计算表明，基于速度与框架角匹配的平台平台传递对准方法能够得到优于0．15°的对准精度。

The difference of transfer alignment between the platform-platform system and strapdown-strap-down system is described in detail.Then the velocity error equations and the frame angle error equations be-tween 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.
