Study On GPS Receiver Software Designed Technique

Global Positioning System (GPS) has made a technical revolution in wireless navigation .It has various advantages that are unexampled other kindle of navigation equipment: high precision, all-weather suitability, total global coverage. Just because of this, GPS receiver is widely used in both military and civil field. In this case, GPS receiver, as one of important part of GPS, is developing rapidly-new technology emerge and upgrade rapidly constantly. This paper describes the technique of software design and signal processing method in detail. And also describes the design method, information processing, calculation method of GPS receiver's software and the selection method of each parameter. At the same time, gives out software structure and program flow chart of general GPS receiver. The software can meet the requirement for data processing of GPS receiver. This paper can be a reference for GPS receiver's studying and producing.
