Analysis of IRNSS Over Indian Subcontinent

V.G. Rao, G. Lachapelle, S.B. VijayKumar

Abstract:	India is planning to deploy an autonomous regional satellite based navigation system to cover its territorial footprint and surrounding areas. The purpose of this system as any other existing GNSS is to cater to the needs of both specific users (Precision Service (PS)) and civilian users (Standard Positioning Service (SPS)) (Kibe & Gowrishankar 2008). The overall constellation consists of seven satellites, of which three will be in GEO stationary and four in GEO synchronous orbits. This system will be used for surveying, telecommunication, transport, identifying disaster locations and public safety, along with host of other applications. In this research work a deeper understanding on parameters specifically of interest to the receiver community such as availability, accuracy and reliability from IRNSS are explored. The impact of augmenting IRNSS with other GNSS such as GPS and GLONASS is also investigated. Finally, a discussion on how the proposed system lends itself to carrier phase positioning applications is detailed.
