Global Positioning System Presentation

What is GPS? History System segments Basic structure Working Uses Applications Conclusion

“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.

GPS System Segments: The satellite constellation The operational control segment (OCS): The user receiver equipment

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 .

Application of GPS Technology: ‘Motor bikers Now Have GPS Option’

Real Time Train Predictive Arrival GPS System

GPS System to Predict Caltrain Arrivals

There are Buses that use GPS System: the GPS coordinates are beamed to the smart stop which announce when the next bus will arrive.

You can hold GPS system in form of a handheld GPS device i.e

Garmina GPS 72 Handheld System

Car GPS System Car owners can exactly position the car ,then check it with Google earth .Alarm will send SMS to car owner's mobile phone and the center if the car is shocked, or car door is opened, or engine is started, or the car's power is cut off illegally.

GPS Help Protect Your Children? GPS System to Be Available in Children's Shoes

GPS device can tag your teenager

A device the size of a large matchbox is being launched that exactly pinpoints a carrier’s location through a global positioning system accessed by computer or mobile phone.

A GPS device for your dogs & pets

The system links to a GPS-enabled collar for your dog to which help us to locate it.

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.
