Geodesy with the Global Positioning System

EESC G9945 Section 2

Spring Term 2013

Term Project Subgoal 3 Information

Due date: 29 March 2013

Background

The goal is to successfully read and parse the RINEX data file. As always please do not hesitate to e-mail me or stop by (quicker response) if you have questions or are having difficulties.

The RINEX observation file and format

The RINEX GPS data file for the class project can be obtained here. For future need, you might want to explore the UNAVCO web site. (See the link to "Data.") Data from many GPS sites can be obtained here.

What your code should do

Your code should read in and parse the necessary parts of the header, and read in, parse, and store the entire data set. Then, for each specific epoch listed below, provide: PRNs observed, and for each PRN the L1 and L2 phase, the C1 and P2 pseudorange, and the ionosphere-free pseudorange. Also, not all the data in the file will be used in the solution. For example, if one of the phase or pseudorange fields is blank, that indicates that the satellite was not being tracked on all channels. Indicate whether the data point would be used in your solution.
