| 摘要: |
| 在测量船某型号任务的数据处理过程中，通过比对两套外测设备的原始测量数
据，发现方位角的系统误差偏大。针对设备严重超出精度指标的问题，通过进一步的试算，
利用箭载GPS数据进行比对，仔细分析了引起方位角系统误差偏大的各种因素，逐步排查后
找出了问题原因，并由船载设备进行修正。通过排查分析，验证了船载设备零值修正
处理方法的正确性，为船载系统类似问题的解决积累了经验。 |

| Abstract: |
| In data processing of a task by space TT&C ship,it is found out that the azimuth
error is relatively large through comparing t
he data of two measurement equipment.By calculating and comparing
the data of rocket-borne GPS,possible factors causing th
e large azimuth error are analysed and the reason is found.The error is co
rrected by equipment onboard ship. The zero-value correction method proposed is
validated through investigation and analysis,which provides reference for such p
roblems. |
