a satellite-based navigation system made up of 24 satellites placed into orbit by the US Department of DefenseIntroduction to GPS and UTM
Originally designed for military applications, the US government made the system available to civilians in the early 1980’s.Introduction to GPS and UTM
GPS satellites circle the earth twice a day in a particular orbit and transmit signals to GPS receivers.
Triangulation is used to calculate a user’s exact position.Introduction to GPS and UTM
Using four or more satellites, the GPS receiver can determine a user’s 3D motion such as latitude, longitude, and altitude.Introduction to GPS and UTM
UTM is a meter-based global coordinate system developed by the US in World War II.
It works like latitude and longitude system but is easier to convert.Introduction to GPS and UTM
The UTM system is always measured in meters.
There are 60 UTM Zones, each covering 6 degrees longitude from east to west.Introduction to GPS and UTM
There are 10 Zones in the Continental United States.
Maps are on a grid system and positions are defined by the UTM Zone.Introduction to GPS and UTM
The X-coordinate is called the Easting (in meters from western edge of zone)
The Y-coordinate is called the Northing (in meters from the equator)Introduction to GPS and UTM
