机载测姿系统的试飞测评技术综述与评价

Survey and evaluation on flight test of airborne attitude determination system

现代机载任务电子系统的发展对载机姿态的精度提出了更高的要求,试飞测评中需要进行载机任务导航系统在真实环境中的性能动态评估。为此,试飞测评必须动态提供载机姿态真值,以便进行比对。通过简要介绍现今流行的GPS干涉仪、经纬仪、最新天文导航设备和机载精密测量设备等技术,结合当前导航系统技术水平,对上述几种测姿技术从技术关键、应用要点、特征点分布、测姿水平、适用性等进行了比较,针对某导航系统测姿要求对试飞测评提出了建议。

The development of modern airborne mission electronic systems for aircraft attitude put forward higher accuracy requirements,Flight test need in a real environment to dynamic assess the performance of aircraft navigation systems , So, flight test must be dynamically provide aircraft attitude true value for compare. This article briefly describes today＇s popular GPS interferometer,theodolite,the latest celestial navigation equipment and airborne precision measuring equipment , with the current Navigation system technical level, for the several attitude determination techniques were compared from the Key technologies, Application Points, Distribution of feature points, Attitude determination capability, applicability,for the measurement requirements for test evaluate suggested.
