Abstract:

Considering the characteristics of Spaceborne global positioning system (GPS) data, modifications are made on TurboEdit algorithm in aspects of cycle slip threshold setting and parameter setting. Then an improved robust estimation method is proposed based on the traditional robust scheme. The performance of the quality control method in this paper is evaluated by adopting the spaceborne GPS data of the GRACE satellites. The results show that the improved quality control scheme can significantly enhance the cycle slip detection performance, avoid the bad influence of the undetected cycle slip and gross error, and improve the POD results.
