The Indian Regional Navigational Satellite System (IRNSS) renamed as NavIC is used in both the military and civilian communities for navigation, surveying, remote sensing, asset management and precise timing. A number of environmental factors are known to affect the performance of NavIC including electromagnetic interference, multipath, foliage attenuation, atmospheric delays and ionospheric effects. In this paper, the effects of the ionosphere on NavIC will be examined. Ionospheric effects are the most significant disturbance that can affect NavIC users during high sunspot activity. In the presence of glittering, ionospheric modeling can be rendered impractical and receiver performance can be severely degraded. The influence of the ionosphere and a strategy to isolate its effect are a major concern for NavIC positioning and navigation applications. It is also stronger from local sunset until just after midnight, and during periods of high solar activity. If sufficiently intense, these fluctuations can dramatically impact the performance of space-based communication and navigation systems. Therefore, it is desirable to obtain further understanding of ionosphere and its effects on NavIC.

Abstract


The Indian Regional Navigational Satellite System (IRNSS) renamed as NavIC is used in both the military and civilian communities for navigation, surveying, remote sensing, asset management and precise timing. A number of environmental factors are known to affect the performance of NavIC including electromagnetic interference, multipath, foliage attenuation, atmospheric delays and ionospheric effects. In this paper, the effects of the ionosphere on NavIC will be examined. Ionospheric effects are the most significant disturbance that can affect NavIC users during high sunspot activity. In the presence of glittering, ionospheric modeling can be rendered impractical and receiver performance can be severely degraded. The influence of the ionosphere and a strategy to isolate its effect are a major concern for NavIC positioning and navigation applications. It is also stronger from local sunset until just after midnight, and during periods of high solar activity. If sufficiently intense, these fluctuations can dramatically impact the performance of space-based communication and navigation systems. Therefore, it is desirable to obtain further understanding of ionosphere and its effects on NavIC.
