“The Global Positioning System/GPS is a constellation of 24 well-spaced satellites that

orbit the Earth 11,000 miles and make it possible for people with ground receivers to

pinpoint their geographic location.”

History:

Originally established by the U.S. Department of Defense ,the first GPS satellite was launched in 1978.

The first 10 satellites were called Block I. From 1989 to 1993, 23 production satellites,

called Block II were launched. The launch of the 24th satellite in 1994

completed the system.

Basic GPS system

How GPS System Works:The satellites in orbit provide the ranging signals

and data messages to the user equipment. The operational control segment (OCS)

maintains the satellites & tracks in space. The OCS monitors satellite health and signal integrity and maintains the orbital configuration of the satellites. Furthermore, the OCS updates the satellite clock corrections as well as numerous other parameters essential to determining user position, velocity, and time (PVT).

Lastly, the user receiver equipment performs the navigation, timing or other related functions (e.g. surveying).

Uses of GPS Technology

Location- determining a basic position.

Navigation - getting from one location to another.

Tracking - monitoring the movement of people and things.

Mapping- creating maps.

Timing - providing precise timing .

Conclusion: GPS is now being used across the world, the

list of uses is only set by the requirements we can think of applying GPS, as it does so, we find it being used more and more in our daily lives, so it would be hard to perform many travel and industry tasks without it.
