椭球面上精确解算航空器航偏距的算法研究
Research on the method of accurately calculating aircraft yaw distance on ellipsoidal surface
摘要
Abstract
In order to break away from the traditional calculation mode of real-time aircraft yaw distance based on two-dimensional double standard line equiangular cone projection and Gaussian projection,and to avoid errors caused by length projection deformation in yaw distance calculation,geodetic methods such as Bessel geodetic theme calculation and Klein identity equation are used to directly solve yaw distance on the ellipsoid.Multiple equidistant interpolation of geodesic lines,iterative solution,and the algorithm for searching for the landing range and landing point of the yaw angle and the yaw point was tested using two examples and C language programming.The results showed that solving the geodesic line between two points based on an ellipsoid could avoid length deformation and ensure length accuracy.The accuracy of yaw angle and yaw distance can be flexibly controlled by preset iteration termination thresholds.This method provides plan reference for real-time correction of yaw angle and yaw distance in aircraft or ocean.关键词
