一个GPS课程的全部代码，含有数据！很实用(MATLAB GPS SCRIPTS-- Charles Meertens and Doug Miller, U. Utah 3Jan95 These scripts were developed for/during a class in GPS and Active Tectonics Department of Geology and Geophysics, U. Utah, Spring, 1994 EXAMPLE RINEX Files (the only ones guaranteed to work this release) CUR10911.94N CUR10911.94O PAR10910.94N PAR10910.94O Main Program scripts: gpshora.m -- function to calculate Modified Julian Day, Homework#1 HW2.m -- Homework#2 read RINEX observation file and plot C/A code vrs. time HW3_plt.m-- Homework#3 read RINEX navigation file, plot satellite positions HW3_3dplt.m-- Same as HW3_plt.m, but 3d position plots HW4.m-- Homework#4 calculate and plot station position as function of time Functions called: calc_nav.m-- calculate satellite position calc_pos1.m-- calculate station position constants.m-- GPS constants coords.m-- convert x,y,z coordinates to lat, long, height date2j.m-- calculate MDJ eccenr.m-- calculate "E" anomally read_nav.m-- Read RINEX Nav file r)
