What is GPS?

Global Positioning System (GPS) is a network of 30 satellites orbiting the earth to measure the exact location of an object on earth. The satellite sends data through signals and the information is received by a GPS receiver.  The GPS tracker then uses the sent data to find the exact location of the people that matter to you.

Evolution of GPS

GPS was developed by the US government for military navigation. In early 90s, many consumer devices started using this technology and it became useful for common man. Today, GPS technology is incorporated in numerous internet-based utilities, products, and services. The development of this ultra-modern technology is still on-going and engineers from all across globe are working to improvise its accuracy.

How GPS works?

As GPS is a satellite-based navigation system so each GPS satellite encircles the earth in a precise orbit twice a day. Each of the satellite transfers a distinct signal and orbital parameters  let GPS devices to decode and calculate the exact location of the satellite. GPS receivers then use this information and trilateration to calculate the exact location of the user.

After determining the position of your device technology can calculate details such as

·         Track

·         Speed

·         Trip distance

·         Sunset & sunrise time

·         Bearing

·         Speed
