Indian Regional Navigation Satellite System (IRNSS) is fully established and operational, independent and indigenous satellite based navigation system to provide the services in and around India. The real time analysis of the system in field of ionospheric is carried in which the effect of the ionospheric is shown. This ionospheric effects are most varied at the equatorial region of the earth due to its magnetic field, as India is situated in equatorial region its effect are to be considered for position measurement. The method used for measuring the iono delay and calculating the total electron content (TEC) is the method that used for GPS. There’s no particular method or model used for measuring the ionospheric delay for Indian region navigation satellite, here we use Klobuchar model for measuring the TEC and ionospheric delay. Also the grid based model can be used for measuring the iono delay. The effect of iono delay on the position is observed, this give inaccurate location with ionospheric error in measuring the position. The ionospheric is layer build with ions and which is highly influenced by the solar activity. The comparison of IRNSS with GPS satellites is observed, which are tracked at a moment by IRNSS receiver shows the interoperability.
