History of GPS

GPS makes our lives easier, but how much we really know about it.Let\'s take a look at its history and see how this technology has developed in this period.Global Positioning System (abbr.GPS) is a satellite.A navigation-based system developed by the US Department of Defense.
It was originally developed for military use and was provided to the public in the 1980 s.It operates with the help of 24 satellites placed in orbit that are programmed to work 24 hours a day in any weather and anywhere in the world.The 24 satellites orbit the Earth twice a day to send signal messages to the Earth.
GPS receivers located on Earth use the triangle method to determine the location to determine the exact location of the user.In this process, calculate the time required for signal transmission and the time required to receive the signal.After analyzing the time spent, the user\'s location is displayed on an electronic map by taking distance measurements from more satellites.
GPS receivers need to be locked with signals from at least 3 satellites to get a 2D position, 4 or more satellites to get a 3D position.It can also calculate speed, distance and time.The global positioning system is made in the United States.
S.
The Ministry of Defense is working with the Massachusetts Institute of Technology (MIT.In 1951, the U.S.The Air Force hopes to establish a guidance system for the proposed ICBM traveling through the railway.To meet this demand, American physicists and electrical engineersIvan has developed a 3D positioning system that can determine the location based on the time difference of arrival.
This system eventually becomes a platform for global positioning systems or GPS used in our daily lives.Decided to develop advanced satellite navigation systems based on existing US technologiesS.US Air Force and US Air ForceS.The US Navy began using GPS in 1973.It went through extensive testing over the next few years.
Although these satellites have not yet been launched, the first transmitters have been installed and successfully tested with the help of pseudo-satellites (or pseudo-satellites)Satellite) in 1977.In the end, by 1985, 11 satellites were launched into space.On 1980, the United States launched the first Block I satellite with special sensors to detect atomic bombs to monitor Soviet compliance with non-nuclear tests.
In the same year-Motherboard atomic clock, accurate to 1-One in ten million seconds is activated.These clocks measure time by changing the electronic level.GPS was originally developed for the military and was publicly used in 1983.
The tragedy of the Korean airline 007 flight, when Soviet fighter jets shot down a South Korean civilian plane lost on Soviet territory, led to the cancellation of the security rating by the United States at that time.S.So President Reagan allowed the public to use it.On 1986, the tragedy of the Challenger space shuttle further delayed the development of the global positioning system because the space shuttle carrying the second satellite was temporarily suspended.
Eventually, in 1989, 28 satellites were launched for better functionality.In 1990, due to the military\'s need for more receivers to strengthen its military use in the Gulf War, the public use facilities for GPS were temporarily suspended.It was available to the public in 1993.At the same time, it was decided to provide this facility free of charge all over the world.
By 1995, it has become a fairly advanced navigation system.It has achieved a \"full operational capability\" and an increase in the number of satellites, thus improving the availability and accuracy of the technology.In July 1997, 12 series of satellites were successfully launched in January 1997, but were not successfully launched;Most satellites have an experimental payload for rescue and search, the satellite system related to distress.
In 2005,-The M series is launched, and it carries a military signal, a more powerful civilian signal.âx80x98Follow-The IIF Block satellite series was first launched in May 2010 and its final series was launched in February 2016.With some advances in technology, the first series of the third seriesA generation of GPS satellites, launched in December 2018.
Today, this tracking range has grown to 100 m (or even a few centimeters in some cases) and previously has the ability to track objects within 1 m.Completely used by military agencies at a point in time, in real timeTime GPS tracking has become an important part of today\'s aviation, navigation, land measurement and other fields.GPS tracking devices suddenly became the most popularGadgets like GPSCar navigation systems can help drivers track routes, while phones and watches with GPS can help parents look after their children.
