摘　　要：对比了几种传递对准数学模型,比较了其精度并分析了差异的原因。对准时考虑了杆臂效应。仿真时主惯导的数据由轨迹发生器产生,与以往的仿真方法相比,这种方法接近实际情况,更能全面考察所建立的对准模型。Three transfer alignment equations are compared, their accuracies are contrasted and the cause of accuracy difference is analyzed. The considerations of lever arm effects are included in the comparison. The master INS's data is generated by a flight trajectory generator instead of the transfer alignment equations, so the simulation is more close to the reality.
