| Abstract: | The dual-frequency onboard GPS P codes of the ionosphere-free linear combination was used as the basic observations,and taken the majority voting method to detect and delete the oudiers.Then onboard GPS observations from CHAMP satellite was used to simulate and detect outliers,in order to verify the validity of the algorithm.The results indicated that the detection accuracy was relatively high,and also removed effectively the outliers of undifferenced observations.Which provided a good foundation of quality control for precise orbit determination using undifferenced onboard GPS observations. |
