A Satellite Navigation System is a system that uses satellites to find the geospatial position of an object. In our satellite system, the satellites are placed in certain specific orbits around the globe to determine precisely where the receiver is located. To get directions to a new place, we often use the Google Maps app on our phone and follow it with complete confidence as it guides us to our desired location. However, have you ever wondered how exactly this feature works to provide those directions to our destination? The answer to this question has to do a lot with the concept of satellite navigation. Satellite Navigation is a system that uses artificial satellites to determine the geospatial position, i.e., the geographical position of any object. This system is based on information being transferred in an encoded form that we refer to as ‘navigation message’, i.e., the message sent by the satellite (space segment) to the user device (user segment) after obtaining navigation data from the ground stations (control segment).
