7. Surf Report

8. Plans for after Graduation

9. Summer Internship Scripps Institute of Geophysics and Planetary Physics

10. Purpose

11. Provides high precision geodetic and geophysical measurements using Global Positioning System (GPS) satellites, particularly for the study of earthquake hazards, tectonic plate motion, plate boundary deformation, and meteorological purposes.

12. GPS Difference in Position Mm accuracy

13. Where I Work

14. Where I Fit In Real Time Data Processing (RTD) System Precise second by second positioning. Gamit Solutions vs. RTD Solutions. Work out any bias in solutions.

15. RTD XYZ Solutions Tropospheric Delay from atmosphere conditions Ionospheric Delay Statistical Analysis Ionospheric Delay Troposheric Delay

16. Application in the Future Commercial Use of RTD Cargo Ships Plans Cars Personal Use

17. Application for Surveyors Highway Design Geographic Information Systems (GIS) Monitoring Bridges and Structures

18. Application for Science Crustal Deformation Calculate strain build up on tectonic plates Capture seismic event

19. Success of Project Strong horizontal accuracy (1-2mm) Recognized vertical discrepancy ( 20mm)

20. Next Step Continue running a long term test Find results for months worth of data Make results conclusive
