High-Fidelity Earth Gravity Field Mapping from VLEO Constellations (C06)

• Subject Area: Geodesy, Photogrammetry, Remote Sensing, Geoinformatics, Cartography
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 516238647

Based on developments in inertial sensor and ranging technologies, this project aims to systematically investigate all factors relevant to the design of a future multi-satellite mission to measure the gravitational field with a VLEO constellation. Such a mission must, for example, meet requirements from hydrology and atmospheric research in terms of accuracy, spatial resolution and lifetime. Research questions include the sampling properties of constellations, the use of formations and the development of multi-scale spatio-temporal processing strategies.
