Route with Indian Constellation (NaVIC) is the operational name given for Indian Regional Navigation Satellite System (IRNSS) created by Indian Space Research Organization (ISRO) for precise situating applications. In no distant future, the airplanes that are operable in the Indian area will be hand-held with IRNSS L5 and S-band recurrence estimations. The fleeting inclinations comprehend the sign conduct that helps for the security of airplane applications. We proposed a Recursive Least Squares (RLS) method to display the ionospheric range blunder as needs be with latitudinal and longitudinal angle data. The calculation turned out for double recurrence L5 and S-band signs and GPS L1 estimations acquired from IRNSS beneficiaries situated at a low-scope point (16.23oN, 80.44o E). To notice occasional slope varieties, the proposed model run for three long periods of September equinox, December solstice, and geomagnetic-upset action information. The separate all out electron content (TEC) with mean and greatest angles for multi-recurrence signals are talked about. There will be ionospheric gradients which will hugely impact on geomagnetic distributed ionospheric conditions and these decrease the accuracy of the NaVIC satellite system to avoid this we came with the idea of ionospheric gradient analysis using weighted least square algorithm for NaVIC L5 signals.
