Case study: NavIC Performance Observation on Low Latitude Region

The navigation and positioning system is vital in both civil and military applications. It has become an integral part of our day-to-day life. Navigation with Indian Constellation (NavIC) is the latest addition in the area of satellite-based navigation systems. To achieve the required positioning accuracy of any satellite-based navigation system, the performance accuracy of an individual satellite is more important. The effect of artificial or natural error sources on satellite signals depends on their location, traveling path. In this paper, the NavlC L5-band and S-band signals are considered. The digital IF data is used, which is logged from NavIC receiver, and the performance analysis of NavlC signals has been evaluated in terms of Power Spectral Density, acquisition and post-processing parameters like C / No, elevation angle, pseudoranges, ionospheric delay and troposphere delay concerning the location of NavIC receiver at low latitude SVNIT, Surat Station (21 °9'50.04” N, 72° 47’1.26” E). This kind of analysis can be useful for future applications of the NavlC.
