Dynamic and adaptive algorithms of COSMO-SkyMed seconda generazione planner

COSMO-SkyMed di Seconda Generazione (COSMO-SkyMed Second Generation, CSG) is an “end-to-end” and “dual use” (Civilian and Defence) Italian Earth Observation Space System conceived at the twofold objective of ensuring operational continuity to the current constellation (COSMO-SkyMed - CSK), while improving functionality and performances. CSG primary mission objective is to promptly and effectively satisfy the heterogeneous user needs (institutional, scientific and commercial purposes) producing a mission plan that satisfies the higher priority requests and optimizes the overall plan with the remaining lower priority requests according to the users programming rights consumption, while fully employing the system resources and taking into account both technical and managerial constraints. Indeed the CSG Mission Planning and Scheduling tool implements innovative adaptive planning algorithms based on both priority criteria and saturation of system resources that envisage two scheduling strategies, the rank-based and the optimization-based respectively. The CSG algorithms are implemented in an iterative dynamic process of finding optimal solutions able to better answer the demanding requirements coming from the heterogeneous users.
