| 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. |
