My presentation on Wednesday, October 30th is based on the article “Global Positioning System: The Mathematics of GPS Receivers” written by Richard B. Thompson found in Mathematics Magazine.

We will discuss the following three questions:

  1. How does a GPS receiver use satellite information to determine our position?
  2. Why does the determined position change with each computation, even though we may not be moving?
  3. What is done to improve the accuracy of these varying positions?

We will discuss a variable called clock error and how GPS receivers calculate our coordinates using algebra.

I have listed a video below that provides a very basic and brief introduction to the GPS coordinate system.
