Abstract: IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between primary service area and area by the rectangle from Latitude 30 degree south to 50 degree north, Longitude 30 degree east to 130 degree east. This paper is focused primarily on developing a software based receiver for the signals transmitted from IRNSS satellites. Tracking and positioning of IRNSS device is primarily preceded by acquisition stage which involves serial search and autocorrelation methods.
