基于GPS定位的飞机航迹矢量算法

Aircraft Track Vector Algorithm Based on GPS Positioning

航迹矢量是描述航空器运动状态的一个重要参数,在导航计算、空中交通管理中起着非常重要的作用,基于航空器经纬度坐标推算航迹矢量是一种基本方法,MATLAB中提供的计算公式将地球视为球体导致计算精度不高。提出一种基于经纬度的航迹矢量算法,并利用塞斯纳172R机型的飞参数据机型验算。结果表明该算法精度较高、算法计算简便,可以用于航空器监视、领航作业和空中交通管理服务中。

Track vector is an important parameter to describe the motion state of aircraft,which plays a very important role in navigation calculation and air traffic management.It is a basic method to calculate the track vector based on the longitude and latitude coordinates of aircraft.The calculation formula provided by MATLAB regards the earth as a sphere,which leads to low calculation accuracy.A track vector algorithm based on latitude and longitude is proposed,and the flight parameters of the Sesner 172R aircraft are checked according to the aircraft model.The results show that the algorithm has high accuracy and simple calculation,and can be used for aircraft monitoring,navigation operations and air traffic management services.
