Analyzing the Accuracy of SPP

Analyzing the accuracy of single point position using Matlab.

• Read RINEX navigation file reformat into Matlab Eph matrix.
• Open a RINEX observation file (GPS-only or GPS-GLONASS mixd) analyse the header and identify observation types.
• The function fepoch0 finds epoch time and observed PRNs. Next we read the observations and use recpo_ls to get a least-squares estimate for the (stand alone) receiver position.
