ABSTRACT
Indian Regional Navigation Satellite System (IRNSS) is an indigenous system established, run and fully controlled by ISRO. Till now the constellation of the IRNSS is design for seven satellite and can be increased further, the series named to this satellites are 1A, 1B, 1C, 1D, 1E, 1F and 1G out of which five satellite are present in the space and two of them are planned to deployed by the end of year 2016 so full system will be in operation by the end of this year. This paper present the signal generated in MATLAB using simulink model and modulation of the same signal for IRNSS system. The C/A code of L5 signal of IRNSS is generated and used for modulation. This can be further carried for determination of the signal delay due to ionosphere effect. Also this signal can further carried for acquisition and tracking purpose. This paper includes five section Introduction, signal specification, C/A code simulink, modulation model and conclusion.
