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:
- How does a GPS receiver use satellite information to determine our position?
- Why does the determined position change with each computation, even though we may not be moving?
- 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.
