What is GPS ?
GPS stands for Global Positioning System and is a satellite-based radio navigation system. While common use of the term GPS began relatively recently,
the system dates back to the 1960s when it was first developed and operated by the U.S. Department of Defense. Article Source:wiki.answers.com
The GPS system was deployed in the 1970s exclusively for military use, today GPS receivers are used by millions of people of private citizens around
the globe for business and recreation.
In today's world one of the most common commercial uses of GPS is Vehicle Location.
The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a group of 24 to 30 Satellites and their Ground stations.
Satellites: The Global Positioning System is consists of 24 to 30 specialized satellites that orbit the globe at over 10,000 miles above the Earth’s surface
continuously transmitting information towards the earth.
Therefore, this information can be "detected" by GPS receivers. A GPS receiver, combined with a small computer, can calculate it's Latitude / Longitude
( Latitude -Lines of Latitude are the horizontal lines shown running east-to-west on maps and Longitude -is the geographic coordinate most commonly
used in cartography and global navigation for east-west measurement.).
The latest GPS system is accurate to within about a meter. Which means whole world is in your hand.
Ground Stations or Control Section:
These stations monitor the GPS satellites, checking both their operational health and their exact position in space. The master ground station transmits
corrections for the satellite's ephemeris-(A table giving the coordinates of a celestial/space body at a number of specific times during a given period)
constants and clock offsets back to the satellites themselves. The satellites can then incorporate these updates in the signals they send to GPS
receivers.
There are five monitor stations: Kwajalein, Ascension Island, Colorado Springs, Hawaii and Diego Garcia.
GPS navigation: The GPS navigation system is designed to have multiple tracking satellites at any given point on Earth to give you global positioning.
GPS navigation is probably one of the most astounding inventions to help us in so many different applications. An example with the GPS You can
tracking your parcel delivery by truck, ocean liner guidance systems, planes or even on your golf cart.
The reason GPS navigation is so widely used is because of the very rapid and high degree of accuracy, which can be used in all weather conditions
and any time you need it no matter where you are on earth. With the use of transmitted radio signals from satellites your GPS receiver has the ability to
find your position within 50 feet (15 m). GPS software is used to take the information and evaluate the position of the GPS receiver.
The Road map GPS users: This type of GPS map will give you accurate information on the network of roads in a specific region. This information
doesn't have to be as accurate because the user is not concerned about how high or lows in the land.

GPS Tracking Devices:
Depending on data communication methods used by a GPS tracking unit, GPS tracking devices are mostly divided into 4 categories:
1) GSM/GPRS Tracking - uses the GSM cellular wireless network to transmit data by SMS or GPRS data format. Most of GPS trackers available on the
market belong to this category. Its trackable area is same as the coverage of the GSM cell phone network.
2) CDMA Tracking - uses the CDMA cellular wireless network to transmit data. Similar to GSM Tracker, its
trackable area is same as the CDMA cell phone network.
3) SAT Tracking - uses global satellite communication network to transmit data. This network covers worldwide anywhere on sea and land. So, it is
most suitable for tracking boats, ships or other targets on the sea where there is no coverage of cellular wireless networks.
4) RF Tracking - uses RF wireless point-to-pont modem for data communication. Its track able area is within
a limited communication distance (typically up to 20 miles). The advantage is no monthly service fee. So, it is suitable for tracking people who work
together within a limited area range.
To choose a category, you should consider your tracking area and the wireless network coverage.
GPS Coverage by Google map around: (1) North America, Europe, Australia New Zealand 90% (2) South America and Caribbean 80% (3) Asia 40%.
