Abstract


GPS since put into use on people's lives had a profound impact . Provides a high precision geodesy , geodynamics , geophysics, celestial mechanics , manned space science , global oceanography and global meteorology and weather measurement technology . Today , satellite navigation has become truly multi-disciplinary and cross-sectoral, wide use, highly effective comprehensive high-tech . First, the composition and characteristics of the navigation system , as well as domestic and foreign research status , complete GPS Positioning Algorithm for Modeling and Simulation using MATLAB and C on the basis of full understanding of the software receiver and GPS navigation and positioning principles . Then frame synchronization algorithm and two pair , parity , user location solver , longitude and latitude into sub-module optimization , faster processing speed . The positioning accuracy from 150 meters to 30 meters . In order to further improve the system operation speed and reduce storage overhead , and analysis of a single-precision fixed-point , double-precision fixed-point , pseudo- fixed-point , block floating-point to fixed-point and analog floating - point and five kinds positioning solver program . Simulation analysis proved , GPS positioning solution far more than the ARCA3 32-bit wide span of data format from 2 -55 th power to 32 power , but reduces the computing speed of mind and therefore not suitable for fixed-point processing method . Due to the limitations of the hardware with a simulation of ARCA3 comes floating point capabilities , but it is recommended that a full floating-point operations . Assessment applications RTL system-level simulation platform positioning and navigation algorithm to calculate the amount of each algorithm module , the number of instructions detailed statistics and computing time , detailed statistics count the running time of the trigonometric functions affect the positioning solution analysis for ARCA3 characteristics , proposed three improve the operation speed of the program : specialized processing unit for the calculation of the trigonometric functions ; optimal solution equation : Add the floating-point unit . After assessment of the improvement program , the operation speed is significantly improved.
