摘　　要：主要讨论了采用光测设备测量模型自由飞的轨迹问题。针对模型自由飞的特点,综合利用两台小型激光电视测量系统(OKA)、GPS、全站仪(TCRA1101)等现有设备,设计了安全、可靠的模型自由飞跟踪、测量方案;利用方向余弦交会算法,对测量的模型自由飞数据进行处理,并采用两种不同的方法进行了测量精度检查,结果表明测试精度满足测试要求。The problem of track measurement of model free flight by optical instrument is studied mainly. A test scheme of trajectory measurement in security and reliably with OKA, GPS and total station positioning system （TCRA1101） etc is established. Synchronously, a method is presented on two OKA by direction cosine inter- section in the measurement, also two different methods are adopted to check up the precision and the expectant results are obtained.
