A Comparative Study of Position Uncertainty in NavIC and GPS

Global Navigation Satellite System (GNSS) is system which uses satellites which allows users to determine their location and time up to a very high precision. Most common GNSS is Global Positioning System (GPS) developed by USA. India has recently developed its own GNSS called Indian Regional Navigational Satellite System (IRNSS). This paper analyses the uncertainty in position provided by IRNSS and GPS.
