Earth Observation Division

In this research division, research will be done in Gravity, Global Navigation Satellite System (GNSS), Optical, hyper-spectral and Radar Remote Sensing to investigate earth’s system integral components like geosphere, atmosphere, hydrosphere and biosphere.

Geodetic Research Group

The research areas of this group focus on physical and geometric geodesy to study the Earth's shape, size and dynamicity. Research in physical geodesy studies the physics of earth's gravitational field to determine geoid and theory of geopotential height systems,temporal gravity field variations and its applications to global mass distribution and transport, oceanography and geodynamics.

Geometric geodesy aims to use Global Navigation Satellite Systems (GNSS) to define,maintain and provide a highly accurate, consistent and stable geodetic reference frames that can be potentially used for surveying, positioning and navigation. The research in GNSS geodesy extends to studying the time and space variations of position coordinates of Continuously Operating GNSS Reference Stations to identify subtle deformation of the solid earth.

Our geodetic group's future priority areas is to expand research in other space geodetic techniques including Interferometric Synthetic Aperture Radar (InSAR), Altimetry and Satellite Laser Ranging for better understanding of the Earth system.

Remote Sensing Research Group

The research activities of the remote sensing research group is to integrate geospatial,GPS, optical, and radar earth observing remote sensing satellites datasets to study the most pressing environmental and atmospheric issues including forestry and ecosystem,agriculture, climate change and adaptation, geology, hydrology, geo-hazard, land use/land cover, urban planning and development, cloud and fog cover, oceanography and Planetary and cosmology applications. The future research priorities of remote sensing research group are to establish ground satellite data receiving station, receive and archive remotely sensed data for early-warning and real-time planetary system components monitoring,assessment and forecasting system.
