If you go to an unknown place, then you must be using GPS to track your location and reach your destination, but have you ever wondered what is there in GPS that gives your location within a few seconds? In this post I will tell you what is GPS system and how it works. What is GPS system and how is it used in Hindi.
What is GPS System
The full name of GPS is Global Positioning System. GPS is usually a Satellite Based Radio Navigation System which is used to know the location, like if you are stuck in any problem then you can take help through emergency number. which are present in all mobile phones nowadays
History of GPS
GPS was first launched by the American government as a project for military purposes in 1973. The first satellite under this project was launched in 1978. At that time GPS was used only by the American military. With its help, the American military used to accurately target and kill enemy aircraft and their military.
After this, in 1983, a flight which was going towards Russia, at that time there was no GPS system in the airplane because GPS was made only for the American military. About 269 people were going in this airplane, but this plane accidentally landed in Russia. He went to an area where he should not have gone, that is, he went to a restricted area of Russia which was destroyed by Russia. After this incident, the then US President Ronald Regan decided that now GPS should be used all over the world. Will be provided publicly in
But at that time, about 24 satellites were required for the whole world, so to make GPS available to the common people, the first satellite was launched by the American government on February 14, 1989 and the 24th satellite was launched in 1994, in 1995. For the first time, GPS was opened to the common people but at that time its accuracy and quality were not so perfect.
By 2000, the US government had made many efforts to improve GPS. As a result, today GPS has started working properly all over the world.
How GPS Works How GPS Works
Your smart fone Or any GPS unit has a GPS receiver which receives the signals sent by the satellite. You must know that the satellite rotating in the earth sends the signal after a time. In these satellites, the signal and its time are first. Atomic Clock is used for correct calculation of time in these satellites. This is such a clock which can tell the correct time for millions of years.
The chances of these clocks getting damaged are very less. When the signals of these satellites come in contact with a GPS receiver, then the receiver reads those signals, in this the receiver also finds out which satellite the signals have been sent from. At what distance is it located? If your device is successful in receiving signals from four or more satellites, then you get to know your current location.
A normal GPS device which has not been used for a long time also takes 15 to 20 minutes to show its location but if you use GPS in your smartphone then you will know your location in a few seconds. This happens because A-GPS or Assistant GPS is used in mobile phones. This is also a form of GPS but it detects the location quickly by using the internet.
GPS situation in India GPS location in India
In today’s time, apart from GPS, Glonass is the only navigation system which provides its services worldwide. Now India has also made its own navigation system. Currently, this system is available in India only and it has coverage up to 1500 km area from the border area. In the coming times, India is also working on many projects to strengthen its navigation.
