Simulation and evaluation of the orbital parameters and novel inertial sensors of the MAGIC-like gravity mission

Kurzfassung

Satellite gravimetry missions have significantly contributed to the analysis of Earth’s gravity field. Past and ongoing satellite missions have delivered insights into dynamic mass redistribution of the Earth. However, in current satellite gravimetry missions there are certain limitations in terms of spatial and temporal resolution. One of the reasons behind this being use of single satellite pair configurations. Advancements to mitigate limitations in current satellite missions need to be explored. The thesis focuses on optimization of different design aspects for recovering gravity field accurately. Simulation were carried out for based on orbital parameters and sensor configurations of future missions, for example, using the Bender constellation. Analysis of inter-satellite drift and global coverage for near polar and inclined satellite pairs was done. The results emphasize all advantages of double satellite pair orbits and advanced sensor technologies like standalone CAI accelerometers in terms of better recoverable gravity field accuracy. These results bridge some important knowledge gaps for future satellite gravimetry missions, reinforcing how recent sensor advances can complement novel orbital design approaches.
