Testing the conformity of GPS and IRNSS in terms of ionospheric delay and position errors

Abstract

With the establishment of Indian Regional Navigation Satellite System (IRNSS), India envisages to have an independent navigation system apart from GNSS. This system also brings great opportunity to the space science community to compare and study its performance with existing satellite-based navigation systems. The present study is focused on the variations of the IRNSS signals at different frequencies as well as with GPS, based on the parameters of ionospheric delay and receiver position.
