摘　　要：根据试验任务的特定需求,部分试验需在野外开展。通过分析野外测试情况下不同目标测量模式的工作原理,建立了测量解算数理模型,并进一步推导误差传递函数,仿真计算误差曲线。仿真结果表明,单站定轨精度比交会测量高一倍。在此基础上,明确各种工作模式对仪器设备的精度要求,为制定试验方案提供参考意见,为野外试验中仪器选取、测量精度预计、误差分析等提供理论依据。According to the specific requirements of the test task,some tests need to be carried out in the field.By analyzing the working principle of different target measurement modes in field test,the mathematical model of measurement solution is established.The error transfer function is further derived,and the error curve is simulated.The simulation results show that the orbit determination accuracy of single station is twice as high as that of convergent measurement.On this basis,the accuracy requirements of various working modes for instruments and equipments are clarified,which provides reference for the formulation of test scheme,and provides theoretical basis for instrument selection,measurement accuracy prediction,error analysis,etc.in field test.
