Abstract: Based on the research of orbit determination by using two GPS satellites,this paper discusses the initial value problem and provides an effective method of getting initial value.Computer simulation shows this approach can give a certain and practical initial value.As a result,the amount of calculation is cut down consumedly and the convergence performance of the algorithm is improved.This technique is superior to the traditional guess method in the engineering area.
