【摘要】 根据单位矢量法测轨原理，在人造卫星初轨计算的单位矢量法（ＵＶＭ１）（１）的基础上，给出了利用人造地球卫星观测资料测定有摄初轨的一种方法（ＰＵＶＭ１）。本方法既适用于测角资料，也适用于测距资料和测速资料，以及这些不同类型资料的各种组合；适用于任意偏心率、任意轨道倾角的人造地球卫星；有利于提高初轨测定精度，并改善整个计算过程的收敛性。更多还原

【Abstract】 In this paper,a method considering perturbation is presented for initial orbit determination,according to the principle of Unit Vector Method(UVM).This method is applicable to not only angle observations,but also distance and velocity observations and different combinations of various types,It’s suitable to the orbit of any eccentricity and any inclination.It is beneficial to improve accuracy of orbit determination and convergency of algorithm.The simulated and practical computational results show that this method is reliable and effective in the case of suitable arc length and sample density of observations.更多还原
