| Abstract: | In order to keep the precision of time synchronization between satellite and ground for the satellite navigation system,the time-delay characteristic of antenna rotatory joint is required to be well.Three types of rotatory joint including of non-osculating,osculating and cable substituted are analyzed with the representative time-delay test.The result shows that the fashion of cable substituted has better character. |
