摘要
In this paper, the authors developed the GPS post-processing software system for airborne gravimetry,which is called EGPS,on the basis of the concept of software architecture.The software is the integration of different functional components according to certain interactive mode.EGPS uses the method of pseudo-range difference to get the position,and employs the method of Doppler frequency shift to get the velocity of the aircraft carrier with high accuracy.The paper presents the processing results of actual airborne gravimetry GPS data using EGPS.The data support a conclusion that EGPS has basically met the requirement of airborne gravimetry for GPS post-processing.
