Impact Study of Terrestrial Jamming on GNSS Receiver On-Board Launch Vehicles and Mitigation Technique Using RF Switch

<div class="section abstract"><div class="htmlview paragraph">Global Navigation Satellite System (GNSS) receivers are widely being used in aerospace as well as automotive applications primarily for navigation applications. ISRO uses indigenously developed GNSS receivers in its Launch vehicles (LV) mainly for POD (Preliminary Orbit Determination) and for INS aiding in long duration missions. Advanced GNSS receivers are being developed and used in ISRO’s new generation launch vehicles
