Abstract

This paper describes a comparative study of ionospheric observation over central part of India at Indore-Simrol using Indian Regional Navigation Satellite System (IRNSS) and Global Navigation Satellite System (GNSS) . The IRNSS with an operational name of Navigation with Indian Constellation or NavIC,is an autonomous regional satellite navigation system. It covers India and a region extending upto 1,500 km and the system at present consists of a constellation of seven satellites. On the other hand, GNSS which comprises of GPS,GALILEO,GLONASS,etc is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. © 2019 URSI.
