GEOS F493 / F693 - Geodetic Methods

1. GPS

This section focuses on GPS and introduces how it works; signals transmitted; how to get positions, velocities, and time; error sources and mitigation strategies; and how to exploit potential error sources as your signal.

Reference Materials

I rely heavily on these books:

• Global Positioning System: Signals, Measurements, and Performance Revised Second Edition (2011) by Pratap Misra and Per Enge; This is definitely the main reference! The authors explain all aspects in great clarity!
• Algorithms for Global Positioning by Gilbert Strang and Kai Borre
• Global Positioning System: Theory and Practice by Bernhard Hofmann-Wellenhof, H. Lichtenegger and J. Collins, I got the 2nd edition (1993) of this book only, I guess I am old. I haven't looked at the differences to the 5th edition (2001)
