飞机着陆时的轨迹姿态参数是新机设计鉴定和定型的重要参考依据，采取合理的测量手段获取这些参数至关重要。本文根据任务需求，构建了一套实用的飞机着陆轨迹姿态测量及监控系统，采用光纤传输进行远程控制与数据交互，实现多台高速摄像机的远距离集中控制、统一授时、同步采集、测量数据快速下载处理，实现飞机着陆时轨迹、速度、飞机偏航位移、飞机姿态等参数的精确解算和实时监控。经飞行试验验证，结果表明本系统稳定可靠、处理结果精度高，满足任务要求；同时该测量方法具有较高的实际工程应用价值，不仅适用于飞行目标的轨迹姿态测量和其他类似运动物体的运动参数解算，其数学模型还具有多种型号的推广性。

The trajectory and attitude parameters are the important reference to type qualification flight test.It will make great sense to design a viable method to measure them.According to the mission requirements,A Practical Measuring and Monitoring System is proposed in this paper.Credible remote control and data transition are used to achieve centralized-control of multiple high-speed cameras, unifying time service,synchronal acquisition,test data quick downloading and analyzing.A credible mathematic model is founded to calculate the trajectory,velocity,airplane departure to the centre line of runway,aircraft attitude etc. during landing. The system is proved in flight test.The results show that it has the advantage of high stability, high accuracy. The method could satisfy mission requirements and is valuable for engineering application.It is not only applicable for high-precision attitude measurement and other similar moving subjects attitude calculations,and the mathematic model can also be extended to relative engineering fields.
