    Title

    Large Constellations & Fleet Operations

    type

    oral

    Description

    Access to space has been simplified and opened the door to a wider range of applications. Organisations are opting for distributed architectures of satellite constellations instead of single-satellite missions. The complexity of the overall system has shifted and necessitated a focus on efficient management and operation of a multitude of heterogeneous smaller elements. This session addresses the operations of large constellations, covering all related elements and phases; the operations concepts and solutions, the required ground segment architecture, the scale-up, deployment, and exploitation, the space traffic management approaches, end-of-life management, as well as the advantages, challenges, the outlook and foreseen developments.
