In-House Translational R & D

1. Conformal Antennas for GNSS/NavIC

Development of compact, low-profile antennas that conform to the surface of a platform (such as aircraft, UAVs, vehicles, or satellites) without   compromising signal reception. These antennas are optimized for GNSS and NavIC signals, enabling integration in applications where aerodynamics, stealth, and aesthetics are critical.

2. Ionospheric TEC Studies at IIT Tirupati Station

Continuous monitoring and analysis of Total Electron Content (TEC) in the ionosphere using GNSS data collected at the IIT Tirupati station. These studies improve understanding of ionospheric variations and their impact on GNSS signal accuracy, supporting better modeling, forecasting, and correction algorithms. 

3. RF Sub-Component Designs for L1, L5, and S-Band

Design and development of high-performance RF front-end sub-components—including filters, low-noise amplifiers (LNAs), and mixers—tailored for the L1, L5, and S-band frequencies. These components ensure minimal signal loss, reduced noise, and enhanced sensitivity for GNSS and NavIC receivers. 

4. Non-Uniform Array Antennas for GNSS

Engineering of non-uniform array configurations to achieve superior beamforming, reduced sidelobes, and improved multipath rejection. These designs enhance positioning accuracy and robustness, especially in challenging environments like urban canyons or under foliage. 

5. 5G/6G + GNSS Integration for Precise Positioning

Research and development on integrating next-generation 5G/6G networks with GNSS technology to achieve centimeter-level positioning accuracy. This hybrid approach leverages the high data rates, low latency, and dense cell infrastructure of 5G/6G with the global coverage of GNSS for applications in autonomous systems, smart cities, and IoT.
