Which GPS systems have been developed?

navigation systems, GPS technology was originally developed by the U.S. Department of Defense and is designed for military use to track enemies, and they know that their position at all times. after the Second World War, to be exact - are tracking technology is actually a bit 'of time.

GPS Navigator II design is based partly on the basis of radio navigation developed in the 1940s, that war were in the world. These systems are named and LORANDecca Navigator and had to know where was the enemy so you can concentrate attack or retreat, depending on the size of forces.

Further inspiration for the modern GPS systems and handheld GPS in 1957 when Sputnik was launched by the Soviet Union in Life A team of scientists monitored by Radio Sputnik and found that due to the Doppler frequency signal was transmitted above the satellite approached, and lowerit went away. The Doppler effect is the change in frequency and wavelength of a wave as perceived by an observer than a movement toward the source of the waves.

The team of scientists has been monitoring Sputnik's radio transmissions soon realized that because they knew their exact location on the globe, they could pin point where the satellite was in its orbit by measuring the Doppler distortion. This was innovative and very exciting for the military at the time. This technology have used both laser radar detectors.

The U.S. Navy's first satellite navigation system used, called Transit. E 'was first successfully tested in 1960 and was crazy enough to everyone that the armed forces. tested at the marine transit, they have done in the hope of some very concrete results. With a constellation of five satellites have found that the system could be an aid to navigation corrections about once every hour supply. The current GPS navigation systems like the Garmin Nuvi> Use GPS to twelve satellites positioned to block immediate corrections.

In 1967, the Navy has developed satellites Timation, which has demonstrated the ability to provide accurate space clocks. This is a technology, the GPS navigation system is based on. In 1970, the plan-Omega navigation system based on a comparison of the phase signal, the first worldwide radio-navigation system. This was the foundation block and the construction of today's GPSPortable.

In February 1978, the first experimental Block-I GPS satellite systems GPS and launched the space of modern development began. These initial satellites were originally manufactured by Rockwell International. Well, we use the GPS satellites are manufactured by Lockheed Martin.

In 1983, Soviet interceptor shot down a civilian airliner KAL flight 007 that flew into restricted Soviet airspace. This heinous act killed all 269 people on board - all of them were civilians. Shortly after President Ronald Reagan announced that GPS would be made available for civilian use when completed. Because of this terrible act, by the Soviets, developed by the GPS navigation has been improved more than ever, and experiments began in earnest.

Until 1985, ten more experimental Block-I satellite launched into space the concept of validation> GPS and 1989, the first modern Block-II satellite was launched. By December 1993 the GPS constellation to achieve initial operational capability later, and only one month, complete with 24 satellites in orbit with a full operational capability was declared by NAVSTAR in April 1995.

One year after President Bill Clinton recognized the GPS to civilian users and military users, explains the importance that he did issue a policy directiveGPS for military use a dual system for civilian purposes and. He formed a cross-departmental GPS on board which the state was responsible for managing GPS as an asset of the Kingdom. With this came the commercial brands such as Garmin GPS.

Plans began in earnest to improve the system for everyday users of the navigation system. An announcement was made that the government wanted to upgrade GPS with two new civil The signals, which would become the accuracy and reliability of users of lead, especially with regard to flight safety. Even handheld GPS would be done.

Since those early years, GPS technology has developed into something every day that public uses and uses with incredible accuracy and reliability. What a way to keep in mind our enemies will now be used to help us on the road during tours and excursions. These companies like TomTom, Magellan and Garmin Nuvi> GPS companies have done it.

In fact, the GPS system, we now have many applications, including map making, land surveying, and chambers of commerce used. Moreover, because of the way-GPS accuracy can be identified with a breathtaking view, the researchers use networks in many applications including the study of earthquakes and synchronization of telecommunications. Who knew that golf would be the situation with a GPS device with the determination of the distanceFlag.

New uses for GPS systems have been constantly discovered, and the way in which technology is evolving, we are confident that more will be new applications for GPS systems. There will probably always be conversion, because the system constantly improve. The next time your on the road, certainly the view of the car next to you and to see if it contains a Garmin Nuvi GPS can be.
