| Abstract: | According to the characteristics of Yuanwang TT&C ship's dynamic tracking on spacecrafts,this paper analyzes all kinds of elements that may affect velocity measuring data of ship-borne exterior trajectory measurement equipment.It puts forward the idea of performing error correction of the data,presents corresponding formula and also makes some checking computations by taking realtime measuring data in certain spacecraft launching missions as examples.The result shows that using velocity measuring data after error correction in preliminary orbiting computation can effectively improve the orbit determination precision. |
