| 摘要: |
| 为了分析航天测量船船位误差对船载外测数据的影响，从理论上推导了船位误差对
外测数据影响的数学模型，在此基础上，通过数据试算定量分析了船位误差对外测定轨结
果的影响。结果表明：船位误差对仰角的影响可以忽略，对斜距的影响范围为定位系统的精
度，对方位的影响与观测距离和观测仰角有关；对定轨结果的影响随着观测距离的增加而
减弱，在距离较近的情况下是一项不可忽略的误差源。 |

| Abstract: |
| In order to analyse the influence of ship′s position error on TT&C shi
p borne outertrajectory measurement data, a mathematic model is deduced and t
he influence is analysed quantitivelly based on the mathematic model. It is
demonstrated that the influence on elevation can be ignored, the influence on r
ange is determined by the accuracy of ship′s position, the influence on azimuth
is pertinent to both range and elevation. As the range rises, the influence of
ship′s position error on orbit determination decreases, to the lowrange targe
t, the influence of ship′s position error can not be ignored. |
