| 摘要: |
| 设计了一种用于海上活动站通过卫星信道进行时间比对的应用系统。结合目前活动站通信现
状, 选择卫星双向时间比对作为对时手段, 综合分析了影响对时精度的主要因素，并在系统
的设计过程中加以克服, 使系统精度达到设计要求。实际卫星信道测试数据表明,卫星双向
对时应用系统对时精度达到微秒级, 满足海上活动站使用要求。 |

| Abstract: |
| A shipshore time synchronization application system through satellite channel
is designed for TT&C ship. According to actual TT&C ship shipshore comm
unication status, the Two Way Satellite Time Synchronization(TWSTS) method is ch
osen to minimize the time synchronization error. After analysis of major error a
ffects in time synchronization, a shipshore time synchronization application s
ystem is designed to minimize the time synchroniz
ation error.The test result through the actual satellite channel shows that the
system′s accuracy is up to microseconds and the demand of the shipshore commu
nication in TT&C ship is satisfied. |
