Abstract: This essay examines the question: How does GPS rely on geometry and trigonometry now that there are satellites? Has the function of geometry and trigonometry in triangulation and navigation changed since satellites were built?
My main resources were websites and articles that I found online. I tried to find recent sources so they would be more valid. The sources gave me equations and lots of details about how GPS works and other forms of navigation that were used before.
GPS still relies on geometry and trigonometry but not a lot. GPS is an advanced method of the LORAN method that was discovered during World War II. GPS uses advanced trigonometry and geometry in the programing to help pinpoint locations. The function of geometry and trigonometry in triangulation and navigation has completely changed since satellites were built. People no longer use calculations using geometry and trigonometry. And satellites are now mainly used in navigation of ships and aircraft. Table of Contents
