A VC++ Based GPS Software Receiver

The research is engaged on the development of a PC based software receiver.The receiver collects the GPS navigation signal by a self-designed signal collector and the signal data is stored in hard disk of PC.A VC++based software receiver is adopted to realize acquisition,tracking,navigation and dialog interface.The VC++based GPS software receiver is introduced.The designing methods of the signal collection system and the whole software structure are provided.The signal processing method and the positioning methods are also provided in detail.The working performance of the GPS software receiver is introduced under Spirent signal generator.The test result shows that the introduced GPS software receiver can realize all functions of the hardware receiver and possess good acquisition and tracking performance.The methods introduced are suitable to software receiver of all satellite navigation.
