Write the uses and working of GPS. How can the techniques of satellite

1.	Write the uses and working of GPS. How can the techniques of satellite remote sensing and geographic information system be made use of in the following areas?
Answer» Uses : Helps in sensing latitudinal and longitudinal location, elevation of objects on earth’s surface along with corresponding time. Working : GPS has a group of 24 satellites that orbit around the earth in 6 different orbits between the altitudes 20000 and 20200 km above the earth’s surface to locate objects. We can locate the places with the help of signals received from the satellite in our handheld device. A GPS should receive signals from at least 4 satellites to display the information like latitude, longitude, elevation and time of a place.
