Abstract
A method for calculating current position coordinate is applied to a global positioning system (GPS) receiver. When positioning at a current time point, the GPS receiver directly calculates a code delay and a carrier frequency of each satellite and position coordinate of the GPS receiver at a current positioning time point by utilizing an ephemeris data of each satellite and position coordinate of the GPS receiver at a last positioning time point, thereby greatly lowering an operation amount, so as to reduce the power consumption.
