Positioning, Navigation, and Timing 

GNSS LAB

The GNSS Technology Development Cell at IIT Tirupati Navavishkar I-Hub Foundation (IITTNiF) is a dedicated centre for advancing satellite navigation – positioning and precision technologies, with a special focus on India’s indigenous NavIC system. Our state-of-the-art infrastructure includes advanced RF test equipment, GNSS signal simulators, multi-constellation reference receivers, antenna measurement systems, and industry-grade design tools—enabling complete development from concept to prototype.

 We undertake cutting-edge research and product development in GNSS/NavIC antennas, RF front-ends, receivers, ionospheric studies, and integrated systems, with application focus areas including space systems, defence navigation, autonomous vehicles, and collaborative projects with line ministries and strategic sectors.

 In parallel, the Cell conducts training, skilling, and capacity-building programs for students, researchers, industry professionals, and startups, fostering hands-on expertise in GNSS design, testing, and deployment. Through close partnerships with academia, industry, and government agencies, and by offering “Lab as a Service”, we aim to accelerate indigenous technology development, strengthen India’s self-reliance in satellite navigation, and build a vibrant PNT innovation ecosystem.

 Our mission is firmly aligned with the vision of Viksit Bharat 2047 and Atmanirbhar Bharat, driving India towards technological sovereignty and global leadership in Positioning and Precision Technologies.

ABOUT GNSS 

GNSS provides autonomous, worldwide positioning and navigation, determining a user's precise location, velocity, and time, making it fundamental to modern transport and mapping. It is an umbrella term covering major constellations like US GPS, Russian GLONASS, Europe's Galileo, and China's BeiDou (BDS), with modern receivers using multiple systems to boost reliability. The applications are vast, impacting transportation, surveying (GIS), and timing/synchronisation for utilities and are vital for precision agriculture and emergency services. Its function is based on trilateration: receivers calculate position by measuring signal travel time from satellites. The system requires at least four satellites to solve for a precise 3D location and correct for the receiver's clock error.
