Improving the Position Accuracy of Rover Receiver using Differential Positioning in Indian Regional Navigation Satellite System

Navigation with Indian Constellation (NavIC) is the Regional Satellite System (IRNSS) developed by Space Research Organization (ISRO) to provide position and navigation services for region. NavIC or IRNSS individual satellite constellation which has seven satellites covering subcontinent. Accuracy of standalone insufficient in certain applications such as civil aviation. To improve accuracy performance system, differential positioning technique utilized. In this paper, carried out, considering two IGS (IRNSS-GPS-SBAS) receivers (one reference station other rover), are capable receiving signals from 7 satellites, GPS 12 SBAS 2 satellites. Here, alone considered analysis. The out using pseudorange measurements on L5 (1176.45 MHz), S1 (2492.028 MHz) dual (L5 both) accuracies compared terms statistical parameters Circular Error Probability (CEP), Distance Root Mean Square (DRMS), 2DRMS (twice DRMS). improvement horizontal (2DRMS) rover observed be 78.81%, it 69.14 % frequency 80.73% when standalone.
