| 摘 要： | 针对新一代航天测量船基于静电陀螺监控器（electrostatic gyro monitor，ESGM）的组合导航系统，分析了测量船外测误差模型及对定轨精度的影响。根据误差传播原理对测量船外测误差进行了分析，得到了位置误差的计算公式，为外测数据的使用策略提供依据。结合实测数据对组合导航系统与惯性导航系统的定位误差进行对比分析，结果表明：组合导航系统的定位误差在大部分时间内比惯性导航系统小609／6左右，并且其定位结果更为稳定。

| Abstract: | In allusion to the latest integrated navigation system based on electrostatic gyro monitor(ESGM) on our new survey vessel,the paper analyzes the outside measurement error model and the effect on orbit determination precision.According to the error propagation theory,the author analyzes the outside measurement error,obtains the formula for the calculating of position error and summarizs the use strategy for source data.The calculation results show that the error of integrated navigation system is about 60% smaller than inertial navigation system’s and its orbit determination result is more stabile. |
