GPS is a space-based satellite navigation system that provides location and time information in all weather conditions. Then whether it is situated in any place of the earth or not. This system provides significant capabilities to the military, civil and commercial users around the world.
This GPS is a satellite-based navigation system made up of a network of 24 Satellites placed in the orbit of the Earth. By Department of Defense. GPS was primarily designed to be used in military applications, but in the 1980s, the government made this system available for common people. GPS can work in any weather, in any place of the world, up to 24 hours a day. At the same time, the best thing is that you do not have to pay any kind of subscription fees or setup charges to use GPS.
Definition of GPS
The Global Positioning System (GPS) is a system that is made up of three things that are satellites, ground stations, and receivers.
In this, Satellites act like stars which are in constellations. At the same time, ground stations use radar so that it can be known to know where exactly it is located.
A receiver, which is like the receiver of your phone, is always listening to those signals which are sent by these satellites. This receiver only decides how far it is actually from each other. Once the receiver calculates his or her distance from four or more satellites, then he is able to know fully where he actually is.
Full form of GPS
GPS has a full form Global Positioning System. By using this, anyone can get information of their own position anytime and anywhere.
History of GPS
GPS was first used in the U.S. Was done by the Department of Defense. GPS often refers to the American navigation system called NAVSTAR. Do not confuse it with the term global navigation satellite system (GNSS), GLONASS, or a GPS receiver.
In 1957, Soviet Union launched Sputnik I satellite, so that better geolocation technology could be obtained with the help of its satellite. In 1960, the U.S. The Navy started the submarines with satellite navigation, which later led to the invention of the TRANSIT system.
For a very long time, GPS was only available for governmental use. At the same time, GPS was also made available to the general public.
When was GPS made public?
GPS was made public only after 1983. In the early 1990s,
GPS services were originally partitioned into the Standard Positioning Service (SPS), which was primarily designed for the public. At the same time, Precise Positioning Service (PPS) was used in military use.
