For optimal selection of spacecraft initial orbit determination,an evaluation index system derived from TOPSIS method is introduced. The weights of indices are designed on the base of the statistics analysis and ex-perts′ experience. Then the weighted averaging method is applied to solve the object orbit calculation problem. Finally,the validity and effectiveness of the model and algorithm is verified by two typical examples.
