| 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. |
