摘　　要：航天测量船在海上执行测控任务,其作业环境远比陆站复杂。安装在船上的测控设备的误差来源,也比陆站多,传播途径更为复杂,测量船姿态误差便是其中一项误差源。为了分析姿态误差对轨道的影响,进行了仿真试算,以任务中实测的姿态角作为真实值,对其添加一定的误差后进行仿真,比较分别利用实测数据和仿真数据进行处理后的定轨结果,考察姿态误差对轨道的影响。结果表明:姿态误差是测量船一项重要误差,对轨道的影响能基本在百米级,不可忽视,提高姿态测量的精度,能有效提高定轨的精度。Space-tracking ships must face various complicated job-environment when carrying out a traking task. Compared with TY＆C equipment on land, the error sources are more complex from equipments on ship, and the gesture error plays an important role in these sources. We took the gesture angel from the ac- tual measurement as a true value. After adding a fixed error to it, we carried on simulation and compared the orbit results based on the true and simulated data. We discuss how the gesture error influences the orbit results and find that gesture error is an important error. We can increase accuracy of the orbit measurement by controlling the uncertainty of gesture.
