说明：  多GPS天线姿态确定程序，包括文件读取、单点定位、双差定位、坐标转换以及姿态确定等。
(a MATLAB toolbox for determining the attitude of a rigid platform by means of multiple non-dedicated antennas using global positioning system is presented. The programs embedded in this toolbox cover the RINEX data analysis, single point positioning, differential positioning, coordinate conversion, attitude determination, and other auxiliary functions.)
