摘    要:多传感器动态测量系统中时间严格同步是实现系统实时、准确获取空间目标位置、姿态等信息的关键。围绕解决传感器间数据同步问题,提出针对两台计算机的时间同步方案,制定传感器数据采集方案,提出相应的数据内插算法。综合测试结果表明,提出的方案及算法成功地解决了多传感器动态测量系统中的时间同步问题,系统综合测试精度优于0.05mm,远远高于0.465mm的设计指标。

关 键 词:时间同步  动态测量  GPS  OEM板  激光跟踪仪  激光干涉仪

Abstract:The time synchronization is the key to achieve real-time position and attitude of space target correctly in multi-sensor kinematic measurement system.The project of time synchronization with two computers and data collection is brought forward as well as interpolation algorithm is put forward in order to solve the data synchronization among sensors.It is proved that the time synchronization is achieved successfully,the testing precision is better than 0.05mm which far higher than design value of 0.465mm.
Keywords:time synchronization  kinematic survey  GPS OEM board  laser tracker  laser interferometer
