Global Positioning Systems (GPS) is a satellite-based navigation system comprising around 24 satellites that identify and determine the precise location of an object on earth. Coursera's GPS catalogue teaches you about the science, technology, and applications related to GPS. You'll learn how GPS works, including the role and functionality of the satellites, receivers, and ground stations. Additionally, you'll gain knowledge on how to use GPS data for navigation, mapping, and timing, and understand the role of GPS in various fields such as transportation, aviation, marine, agriculture, and the military. Expand your knowledge on geospatial technology, cartography, and geographic information systems (GIS) through the study of GPS.
