In Part 1 of this two part series, we learned how GPS works. In Part 2, we will look at various GPS applications.

In this lecture, specific uses of the system will be discussed such as GPS in agriculture, maritime port navigation and airport landing systems. Its use in cell phone navigation known as Assisted GPS will also be discussed. The lecture will end with a description of a possible Galactic Positioning System that would use a GPS-like system for navigation in interstellar space.
