Abstract:

CNES is conducting R&D activities, funded within the EU SST consortium, in order to develop new sensor technologies or extend the domain of use of current technologies, with the global objective to increase EU SST autonomy and the performance of its operational services. The study concerning the use of telescope networks and lasers has been granted to ArianeGroup following an call for tender.
Within this study, CNES & Arianegroup have designed and developed new optical surveillance strategies in order to catalog space objects in LEO, MEO and HEO in coordinated or uncoordinated ways.
The first part of these activities was to analyse the state of art within the open literature, and build our own solution from elements found on those papers.
Then surveillance strategies were developed for each orbital region with a focus on LEO and MEO zones.
Both LEO and MEO surveillance strategies have coordination mode : its means the strategies optimize the sky zone to survey taking into account the station location and the sky zone that each station could survey.
Several surveillance modes have been developed for each orbital regime and will be described in the paper.
The performances of those strategies have been evaluated through simulations and an experimentation involving NFOV, WFOV, laser and daylight systems has been performed during a two weeks campaign in order to challenge and evaluate the performances of those strategies.
