Abstract
A method for calculating current position coordinate and a method for calculating a pseudo range are applied to a global positioning system (GPS) receiver. A position coordinate of the GPS receiver at the positioning time point is calculated through an average pseudo range between the GPS receiver and each satellite at a positioning time point. With regard to calculating the average pseudo range between the GPS receiver and each satellite, for each satellite, original pseudo ranges are obtained through calculating a pseudo range between the satellite and the GPS receiver at each millisecond (ms) in a time range including the positioning time point, and then the average pseudo range between the satellite and the GPS receiver at the positioning time point is obtained through calculating an average value of the obtained original pseudo ranges between the GPS receiver and the satellite.
