GNSS Remote Sensing

The research focus is on developing new techniques for remote sensing of atmospheric constituents using Global Navigation Satellite Systems (GNSS). The Indian Regional Navigation Satellite System, NavIC is the latest satellite constellation and our group working on to utilize the S-band signal for developing the early warning system of thunderstorm.

Ø  Climate and Space Weather:

The research focus of this group is to understand climate and space weather events using ground-based and space -based sensors. Machine learning and data science techniques are deployed to investigate and model different physical phenomena.
