dc.description.abstract Indian Regional Navigation Satellite System (IRNSS) is designed to provide Position, Velocity, and Timing (PVT) services, by taking the requirements of clients in India, as well as users/clients in region 1500km from the Indian boundary. Real Time Kinematic (RTK)-IRNSS is a standout amongst the most exact positioning innovation, with these users can acquire progressively cm-level accuracy. It forms the phase tracking estimations of IRNSS signals. In order to get the precise positioning information ambiguity resolution would be of interest; therefore the carrier ambiguity should be resolved ahead any position is computed. In precise positioning applications ambiguity resolution is still an exacting problem. The carrier phase (CP) measurement is limited by estimating an integer parameter, popularly termed as integer ambiguity estimation. On the brilliant side of this paper, the ambiguities are resolved using the antenna swapping strategy. When these ambiguities are effectively settled the high accuracy and precise user position can be evaluated. This paper first thinks CP estimation and their differencing systems to figure exact position of user. The RTK-IRNSS system provides continuous services, and drill meter level standard positioning down to cm-level positioning. The single difference (SD) and double difference (DD) CP measurements are determined and afterward the baseline solution is watched. In this paper, firstly dispense with the noise parameters and making the spotless conditions of carrier phase (CP) measurements. Therefore, related these CP measurements (spot less) to a vector of unknown 3D position, and also computed the baseline solution between reference receiver and user receiver. The user positional error has computed and determines the 3D Root Mean Square Error (RMSE) in both the differencing techniques. The obtained RMSE is 2.6483 meters in single-difference whereas in double-difference is 2.3391 meters. en_US
