摘　　要：将导弹发射点的所有测量误差统一为标准发射坐标系与实际坐标系之间的平移和旋转，建立了这两种坐标系之间的变换关系。通过各坐标系内的制导方程，用小偏差法求出了落点偏差与发射点的坐标偏差、高程偏差、方位角偏差及垂线偏差之间的解析关系式。并按该计算模型，对典型远程导弹进行了计算，结果表明，该修正公式计算精度高，能用于导弹射前修正。All geodetic survey errors on launch point of ballistic missile are merged into rotation and translations between initial standard launch coordinate system and inertial one, a transformation relationship about these systems is established.The analytic formulas are deduced concerning the launch point error, plum deflection, altitude error, azimuth error and impact point error by use of disturbance method according to guidance equations different systems.Finally, calculation is made on typical long range ballistic missile according to the model. The results shows that the formulas can meet required precision in correction before the launch.
