多机组网试飞时间同步方案

时间同步是多机组网试飞的前提和基础。针对多机组网试飞中数据时间同步要求,提出了一种基于IRIG-B码的综合时间同步方案,应用双向时间同步法、单向时间同步法、时间基准法和分段时延测试法实现了多机组网试飞的时间同步,时间同步精度优于1 ms。实际飞行试验验证了该方法合理有效。

A time synchronization approach for multi-aircraft netted flight test

Time synchronization is the precondition and basis of multi-aircraft netted flight test. According to the time synchronization demand in multi-aircraft netted flight test,a time synchronization approach based on IRIG-B code is presented in which two-way time synchronization method,one-way time synchronization method,time base method and piecewise delay test method are employed.With the approach time synchronization for multi-aircraft netted flight test is realized. The time synchronization accuracy is better than 1 ms.Actual flight test demonstrates that the method is effective and also has good performance.
