Global Positioning System (GPS) is a satellite-based navigation system that sends and receives radio signals. A GPS receiver acquires these signals and provides you with information. Using GPS technology, you can determine location, velocity, and time, 24 hours a day, in any weather conditions anywhere in the world—for free.

GPS technology requires the following three segments:
  • Space segment
  • Control segment
  • User segment
Space Segment
At least 24 GPS satellites orbit the earth twice a day in a specific pattern. They travel at approximately 7,000 miles per hour about 12,000 miles above the earth’s surface. These satellites are spaced so that a GPS receiver anywhere in the world can receive signals from at least four of them.
Each GPS satellite constantly sends coded radio signals (known as pseudorandom code) to the earth.

Control Segment
The control segment is responsible for constantly monitoring satellite health, signal integrity, and orbital configuration from the ground. The control segment includes the following sections:
  • Master control station
  • Monitor stations
  • Ground antennas
User Segment
The GPS user segment consists of your GPS receiver. Your receiver collects and processes signals from the GPS satellites that are in view and then uses that information to determine and display your location, speed, time, and so forth. Your GPS receiver does not transmit any information back to the satellites.

The Global Positioning System (GPS), formally known as the NAVSTAR (Navigation Satellite Timing and Ranging), originally was made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, because of its popular navigation capabilities and because you can access GPS technology using small, inexpensive equipment, the government made the system available for civilian use.

GPS Vehicle TrackingFor example, Now there are a several of car that using GPS tracking. It have a function to monitoring of car location or car movement. Many parents was installed GPS tracking on their car or their child car. They installed it to monitor their child driving habits and know where they’ve been going. Another application of GPS tracking was used in car company who have a large number of vehicles. GPS Vehicle tracking systems prove beneficial in supplying current and historical data on routes taken by all their drivers whenever they are in motion. Company who distribute a lot of car from manufacturing plant into showroom will be install this tools to monitoring about their cars. They not want that in someday will lost their cars. This will give a greater loss than if they install this equipment in transportation unit.
