Difference between GPS and Satellite Navigation System

Global Positioning System (GPS):
Global Positioning System provides time and location-based information to a GPS receiver, located anywhere on or near the earth surface. GPS works in all weather conditions, provided there is an unobstructed line of sight communication with 4 or more GPS satellites. GPS is managed by the US Air Force.

    Component of GPS system:

  • Space Segment
  • Control segment
  • User segments

Satellite Navigation System (SNS):
A satellite navigation system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location to high precision. It is based on a wide network of artificial satellites that transmit radio signals in medium earth orbit.



GNSS consist of three main satellite technologies:

  • GPS
  • Glonass
  • Galileo

Let’s see the difference between GPS and Satellite Navigation System:

S.NO. GPS Satellite Navigation System
1 GPS is a fully-functional satellite-based navigation system. Satellite navigation is a system based on a wide network of artificial satellites.
2 GPS satellites transmit continuous microwave radio signals composed of two carriers, two codes and a navigation message. It describes constellation of satellites that provide navigation, positioning and timing services globally.
3 GPS is maintained by the U.S. Department of Defense. It provide autonomous geospatial positioning
4 GPS satellites broadcast timely signals via radio to the GPS receivers. Satellite navigation systems help us to drive across unknown roads, whether by land, sea or air, etc.
5 GPS is a joint name for group of satellites that are orbiting around the earth. Satellite Navigation is a special software that makes use of GPS signals
6 It processes the signal using its built-in software. The position, velocity and time estimates obtained from the satellite navigation system.
