| 摘 要： | 考虑了在外弹道测量中由于定位的测量误差（主要指常值误差）而带来的测速折射修正的误差。从折射修正的原理出发，推导了该项误差的表现形式。理论分析与仿真计算表明，在高准确度测量定轨中该项误差是不能忽略的。给出了扣除该误差的方法，以利于在数据处理中来消除该项误差，从而可提高定轨的准确度。

| Abstract: | Discusses the problem of residual error on range rate refraction by range error in trajectory tracking. From the principle of refraction, concludes a formula of the influence, which must be a term in the refraction residual error model. By simulation and analysis, it is shown that we can not neglect this error in high precision tracking. A method is given to correct this error to raise the accuracy of the trajectory. |
