Abstract
The currently on-going NGGM preparatory activities encompass two parallel Phase A system studies, which are complemented by a science support study with the goal to identify of optimum set-up for a MAGIC constellation regarding science return, technical feasibility, and costs. As an extension of the Phase A science study and preparation for the upcoming Phase B, several aspects are treated in detail, such as to advance processing methods and algorithms towards an integrated L0-L3 processing, to demonstrate the scientific readiness of end-to-end simulations, to quantify the relative contributions of the two involved pairs to the total mission performance, to analyze specific aspects such the optimum set-up regarding short-term products for operational service applications, and to demonstrate the science impact of MAGIC in numerous application fields. Additionally, the study involves technical aspects such as the refinement of L0-L1b inter-satellite distance algorithm, or the in-flight calibration of the accelerometers. In this contribution will we will summarize the main finding of the first phase of the project and report on recent results of the extension phase. The underlying numerical E2E simulations are performed based on realistic error assumptions for the instruments and the involved background models. The simulation results are evaluated against the science requirements defined in the MRD and MRTD, with special focus on new application fields and short-term service applications.
