Abstract: Soon Indian’s mobile phones and cars are to be installed with new and indigenous satellite technology, i.e. Navigation with Indian Constellation (NavIC) developed by ISRO. After successful completion of NavIC, India has become fifth nation in the sequence of countries with independent navigation technology/system. The NavIC technology will be used mainly for terrestrial, aerial and marine navigation along with tracking and disaster management. Here we are proposing the application of NavIC signals for measuring and montoring ionosphere layer behaviour leading accuracy degradation of satellite based navigation and communication systems. This paper presents the computation of ionosphere parameters such as TEC, ROTI and scintillation index (S4 ) using pseudo range and Carrier to Noise density ratio (C/No ) measurements of NavIC L5 and S-band signals. ROTI and S4 results revealed that the impact of ionosphere irregularity is more on L5 than that of S-band signals.
Keywords: NavIC, ROT, ROTI, S4 .
