What is GPS? How does GPS work? What are the benefits of using GPS?

 hi All visitors how are you all hope you are well I am also good Alhamdulillah.

So today talk about Gps. So let's get started


In the past, it used to be a hassle to determine the location, but measuring with a map compass or scale and finding out the exact location was almost impossible, but now we can do it easily with the smartphone in our hands. And that is why the technology used is called GPS or Global Positioning System. It is found in Bengali. It is a universal positioning system. We may not have thought about how much GPS the modern world depends on

GPS technology was invented by the US military to use GPS only on the battlefield, but it has since benefited the general public the most. This system basically monitors the whole world with the help of satellites or artificial satellites and tells its location at the convenience of the customer. Simply put, suppose you are lost somewhere while traveling. Now you are told that you are 320 kilometers away from Dhaka but 320 km from DhakaIt is not known whether you are 150 km away from Chittagong then it is not easy to understand your location but if you are told that you are 115 km away from Cox's Bazar then a conclusion can be reached because these three The distance of the place intersects at that pointIf you must be there then you are in Bandarban at the mentioned distance from Dhaka Chittagong and Cox's Bazar. The exact location of a place can be determined by knowing the three factors of latitude, longitude and altitude using satellite. The combined point of three positions is called coordinate netpoint. The names of two places on earth may be the same but their coordinate points can never be the same. That is why it is possible to determine the exact position with the help of satellite.

Thirty satellites are deployed around the world to cover the GPS system, but twenty-four satellites are needed to ensure this service. The remaining six satellites have been kept as backups so that the GPS system is not disrupted in the event of a sudden breakdown. GPS satellites are arranged in such a way that there will always be four satellites to locate any part of the earth at any given moment, which means you are within the reach of at least four satellites right now. These satellites revolve at an altitude of about 20,000 kilometers above the earth's surface, with each GPS satellite taking 12 hours to orbit the earth once, meaning they orbit the earth twice a day. GPS satellites always send a kind of radio signal or signal, receiving the GPS signal from the earth to tell their position. These GPS chips are attached to all the smartphones of today and even the use of GPS chips in various types of devices including smart watch key ring shoes can be noticed nowadays. The satellite sends the signal and the GPS chips receive the signal. Now the question is how to determine the position? To understand the subject, you need to know the process of signal exchange. The two times when the satellite sends the signal and the receiver receives the signal are recorded, the distance between the signal transmitted and the signal received is measured by this time. These radio signals travel a distance of three kilometers in a fraction of a millionth of a second. This means that it takes less than a second for the signal to reach your smartphone from the satellite. This tiny time interval is determined by the atomic clock or the microscope, the atomic clock is the most accurate instrument used to determine time. These clocks can detect billions of times a second. Receivers usually do not have an atomic clock. They are only connected to a satellite. Only when the distance of a receiver from the four satellites is known is it possible to determine the exact location through GPS. The location of the GPS satellite and the receiver is not easily understood by us ordinary people, because GPS only identifies coordinate points. And software like Google Maps simply presents that point to us with different place names. The US Department of Defense invented GPS technology in the 1960s, naming the satellite system Napster GPS 96, the first Napster satellite to be launched into space. Since 1979, 24 satellites have been used to implement GPS system. There are a total of 30 control rooms in the world to monitor the entire GPS system.The main goal of the project was to use military technology, including the ability to locate lost soldiers on the battlefield or to accurately launch missile attacks from a distanceNot the system.Since the technology is owned by the United States government, their arch-rival Russia has developed its own system called the GLONASS or Global Navigation Satellite System. Also the EU gnss do almost the same thing in Beidu of China and Naveed of India. However, due to the presence of American GPS chips in most of the devices in the world, it can be said that there is no rival yet. We are using GPS for many urgent tasks like ordering food sitting at home or making transactions through mobile banking app. But beyond that, many of us may not know how important the use of GPS is. The modern world of communication without GPS is unimaginable. From military aircraft to ordinary passenger aircraft and ocean-going ships use GPS to navigate the skies or the ocean. Since the advent of this modern GPS system, there have been no reports of any aircraft or ships being lost except in accidents. Even with this system you can't get lost even if you want to. GPS has been used in motor vehicles since 996. As a result, road transport companies are able to monitor where their goods are at the moment, and the use of GPS has prevented significant car thefts worldwide.

We hope you understand and learn a lot from today's post. Stay tuned for more fun things like this.
