Global Positioning System (GPS) is a
satellite-based navigation system. It is made up of more than 24 satellites. It
provides information about location and time in all weather conditions,
anywhere in the world where there is unobstructed line of sight to four or more
GPS satellites. It does not have any subscription fees or setup charges.
GPS was originally meant for military
applications but in 1980s the system was made available for civilian use.
How GPS works
GPS
satellites circle the Earth two times a day in a specific orbit. Each satellite
broadcast a unique signal and orbital parameters that grant GPS devices to
decode and figure the exact location of the satellite.
GPS
receivers use the information and trilateration to figure out user’s exact
location. GPS receiver measures the distance to each satellite by the amount of
time it takes to get a transmitted signal. Receiver then determines a user’s
position and show it electronically to measure your running route, map a golf
course, discover a way home and more.
