【摘要】：在正交分解法的基礎上,導出了彈下點大地緯度的迭代計算公式,進而將再入點或落點大地高引入到地心距的計算中,提出了一種彈道飛行器自由段的大地高約束解析解。數(shù)值仿真分析表明,該解析方法計算效率較高,位置偏差小于50 m,滿足彈道計算、制導及軌道預測等應用需求。
[Abstract]:On the basis of orthogonal decomposition method, the iterative calculation formula of geodetic latitude at the point below the missile is derived, and then the geodetic height of the reentry point or the landing point is introduced into the calculation of the geocentric distance. An analytical solution of geodetic height constraint for free section of ballistic vehicle is presented. Numerical simulation results show that the analytical method is efficient and the position deviation is less than 50 m, which meets the requirements of trajectory calculation, guidance and orbit prediction.
