| 航天测量船外测数据处理精度对航天测控具有着重要的意义。针对测量船测量机理复杂的难题，在分析测量船主要误差源的基础上，提出了测量船四矢量误差的概念，并分析了其对航天测量船外测精度的影响。结果表明，设备本身的测量误差是主导因素，船摇测量误差次之，变形测量和船位测量的误差处于较小量级，最后通过实际应用验证了四矢量误差分析的准确性和实用性。 |

| Abstract: |
| The precision analysis of exterior measurement data based on TT&C ship has an important significance to aerospace tracking and control. To deal with the complicated problem of the TT&C ship measurement mechanism, based on analysis of main error sources,a new Four-Vector-Error analysis method is advanced, and how it affects the exterior measurement precision is investigated. The research demonstrates that the instrumentation measurement error is the dominant factor, followed by ship rocking measurement error, and the errors of ship deformation and position are minor. The Four-Vector-Error analysis method is also applied in practice to examine its accuracy and feasibility. |
