GPS, How to use GPS? & How does GPS work?
What is GPS?
GPS means Global Positioning System which is a network of satellites that send details of their position from space to earth. GPS work. The signals are leaded by GPS receivers such as navigation devices.
They are actually used to measure the exact position, speed and time at all. It is an part and parcel technology in the modern world. GPS is well-known for its military uses. It was first developed by the US to help in its global intelligence efforts at the height of the Cold War. At first GPS system was developed in the 1960s to allow ships in the US Navy to navigate the oceans more accurately.
How to use GPS?
There are many Uses of GPS. Different kind of people uses it in a different way. GPS is used in Android devices which have same global positioning technology as Google Maps and most third-party GPS tools do. The Global Positioning System has a worldwide navigation system of about 24 satellites and their ground stations that originally developed for military use. It helps you to determine the distance and direction from your location to another specified point. You can Mark where you park your car, so you always know which way to get back with the help of GPS. You can also establish your altitude, and track everything which was lost.
How does GPS work?
GPS works with electronic way. There are three parts of a GPS system. A constellation of between 24 and 32 solar-powered satellites usually orbiting the earth in orbits at an altitude of approximately 20000 kilometres. It is a master control station and four control and monitoring stations. Each of the satellites is in an orbit which allows a receiver to scan at least 4 of the operational satellites. The satellites always send microwave signals to a receiver where the built-in computer uses these signals to work out precise distance from each of the four satellites.
