GPS

Global Positioning System (GPS) is a way to naivated based on satelites. The U.S. Department of Defense (USDOD) orginally put up satellites in orbit for military use and then made public for normal civilian use in the 1980's. There are 24 satlieetes that work in any anywhere in the world 24/7 and has no fees or charges.

NMEA Data from GPS

National Marine Electronics Association (NMEA) is the format that defines how GPS data is transmitted between devices. Most of my research uses the GPS receiver output data in the NMEA format.
