Abstract: Based on the research of orbit determination using a single GPS satellites,two effective methods of getting initial value and comparison of their performance are discussed.Computer simulation shows the second method can give a fixed and practical initial value.As a result,the amount of calculation is cut down greatly and the converge performance of the algorithm is improved.This technique is superior to the traditional guess method in the engineering field.
