Profile

About

Himanshu Save is a Senior Research Scientist at the Center for Space Research (CSR), The University of Texas at Austin. His research focuses on satellite gravimetry, space geodesy, and the development of advanced gravity-field and mascon products from the GRACE and GRACE Follow-On missions.

He serves as Science Operations Manager for the GRACE Follow-On and upcoming GRACE-Continuity (GRACE-C) missions and leads the development of Science Data System capabilities for the GRACE-Continuity mission at CSR. His work spans operational gravity-field processing, mission operations, systems engineering, mission design, precise orbit determination, and collaboration with scientists studying terrestrial water storage, groundwater, drought, floods, ice-sheet mass change, ocean mass, sea-level change, and solid-Earth processes.

Areas of focus

Research Areas

Satellite Gravimetry

Development and analysis of gravity-field and mascon products from the GRACE and GRACE Follow-On missions to investigate the dynamics of the Earth system from satellite gravity measurements. Research includes global mass flux estimation, validation and interpretation, operational monthly and high-temporal-resolution gravity solutions, near real-time applications, and the development and analysis of gravity information for diverse Earth science applications.

Space Geodesy

Gravity-field estimation, precise orbit determination, satellite-to-satellite ranging, geodetic reference systems, and analysis of spaceborne geodetic measurements.

Science Data Systems

Development of operational processing systems, software, high-performance computing infrastructure, satellite systems, telemetry science monitoring, data quality control, calibration and validation, and science product generation for the GRACE, GRACE Follow-On, and GRACE-Continuity missions.

Earth System Science

Applications of satellite gravity observations to terrestrial water storage, groundwater, floods and droughts, ice sheets, ocean mass, sea level, and solid-Earth processes.

Future Missions and Systems Engineering

Science, systems engineering, mission architecture, simulation, and data-system development supporting GRACE-Continuity and future satellite gravimetry missions.
