光电经纬仪补充条件定位方法及其应用

在固定翼飞机定点着陆飞行训练过程中,由于测试装备种类数量较少、测试手段有限或装备故障等因素,经常出现测量记录的数据不能满足飞行讲评和飞行质量评估要求的情况,从固定翼飞机定点着陆飞行训练数据分析入手,根据飞机在下滑道中的运动特点,建立了飞机定点着陆训练下滑道段补充条件定位解算的数学模型,在有效测元不足不能运用常规方法进行定位解算的情况下,提供了定位解算的方法。实测数据计算结果验证了这一方法的正确性和有效性。该方法简单实用,可有效提高光电经纬仪有效信息源的利用效率,在固定翼飞机定点着陆飞行训练中具有十分重要的工程应用价值。

Supplementary Condition Positioning Method of Photoelectric Theodolite and Its Application

In the process of fixed wing aircraft fixed-point landing flight training,due to a less number of test equipment,limited test means or equipment failure,it often occurs that the measured data can not meet the requirements of flight comment and flight quality evaluation.Starting from the analysis of fixed wing aircraft fixed-point landing flight training data,according to the movement characteristics of the aircraft in the glide path,a mathematical model is established to solve the supplementary conditions of the glide path section in the aircraft fixed-point landing training.In the case that the effective measurement elements are insufficient and the conventional methods can not be used to solve the positioning problem,a positioning solution method is provided.The correctness and effectiveness of this method are verified by the calculation results of measured data.This method is simple and practical,and can effectively improve the utilization efficiency of the effective information source of the photoelectric theodolite.It has a very important engineering application value in fixed-point landing flight training of the fixed wing aircraft.
