Global Positioning System (GPS) is a constellation of low-earth orbit satellites. These global positioning system or GPS satellites are in an synchronous orbit above the Earth. The system was initially developed and controlled by the U.S. Department of Defense. Today, the system is used in a number of ways by government agencies like the Department of Homeland Security, the Transportation Safety Administration, the Internal Revenue Service and the Federal Emergency Management Agency among others. A Global Positioning System also known as a GPS, has become the backbone of modern mobile technologies such as GPS enabled cell phones, laptops, lap top computers and other portable devices. These devices can be equipped with software applications that provide the user with accurate positioning data.

Global Positioning Systems are operated by ground-based receivers called the pointing, tracking and relaying equipment. These equipments are often installed on fixed points either in the sky or on the ground. There is another category of GPS which goes by different names like operational geostationary orbit, geostationary transfer orbit, satellite orbit, relay timing clocks and fixed position tracking satellites. The operational GPS was first used to track and locate troops in the battlefield. This technique has since been adapted for navigation, mapping, rescue operations and aircraft tracking.

In general, operational goes west is the global positioning system that coordinates GPS receivers located in terminals or satellites to the terminals of users in different parts of the world. It can either use the regular GPS techniques such as plotting positions using latitude and longitude or track routes using latitude and longitude plus a series of other parameters such as speed and fuel consumption. The second type of global positioning system, known as the geostationary orbit GPS, does not require users to plot positions using latitude and longitude but it uses GPS techniques to determine latitude and longitude automatically. Geostationary satellites also provide users with accurate time and location data.

Global Positioning Systems (GPS) have recently become popular among vehicle owners due to its capability to help them with navigation. However, GPS systems have had their fair share of problems in relation to accuracy and reliability of location data. A GPS system used for vehicle navigation may fail to give correct locations if the source of power is lost or goes down while drivers are on the road.

Both the GPS systems, operational goes west and geostationary satellites use the same technology. One major difference between the two lies in the fact that operational goes West cannot command a device located on the ground while geostationary satellites can do so. While operational GPS devices are more expensive than geostationary ones, they are far more reliable. GPS systems today have become a necessity for motorists, pedestrians, criers and others who need precise location information. They also help businesses by improving customer service by providing customers with accurate arrival times.

There are two main types of GPS devices used in automobiles; GPS system that is installed in cars and allows vehicle owners to control it; and GPS system that is installed on receivers which are placed in fixed positions such as tables or desks. Today, GPS manufacturers are making specialized receivers that are suitable for outdoor use such as go-r satellites. For consumers, there is a third type called go-sats which can be installed inside buildings, giving superior accuracy over longitudes. A go-sat is highly effective when fitted inside the building where a vehicle is parked, allowing the location of the vehicle to be determined accurately and quickly.
