GS 608: Introduction to GPS: Theory and Applications
Spring Quarter 2006

Problem Set 3
Using the enclosed handout ‘Trimble Geomatics Office Data Processing’ and
instructions given to you in class use the Trimble Geomatics Office (TGO) software to
process the GPS data collected on May 5, 2006.
1. Use the static data set collected with Topcon Javad Legacy receiver at base
station (“Base”) with RINEX files: 2629125.06O and 2629125.06N, and Trimble
5700 receiver at rover station (“Rover-1”) with RINEX files: 41151250.06O and
41151250.06N. The antenna heights are: 1.49 m to the bottom of the antenna
mount at the “Base” and 1.60 m to the bottom of the antenna mount at the
“Rover-1”. The antenna types are Topcon Geodetic 3 Rev. D for “Base” and
Zephyr Geodetic for “Rover-1”.
2. Use the differential processing mode: select the “fixed” (performing a fixed
integers solution) for your data processing; save your results. Now, select the
“code” (performing a code solution only) solution for your data processing and
save the results. Explain the differences between “fixed” and “code” modes.
After the data processing has been completed, create a full Project Report
including plots of residuals, satellite tracking summary at stations and single-
differenced summary etc.
Enclose the printout of the Report for the solution types that you performed (L1-
fixed and code). Discuss your results.
3. Perform the coordinate conversion between the SPSC 1983 (N/E/H/h), which is
your primary output reference system, with WGS 84 (lat/lon/h) solution for the
L1-fixed solution and save it in your local directory. Here are the steps:
Press Select All in Geomatics Office
Press File/Export and then choose Custom tag.
Select Name/Latitude/Longitude/Height (WGS84 decimal degrees)

Give the export file name and press save. These exported files can be
found in Export sub directory in your project directory.
Provide printouts of your results.
