Precise Emulation of Command end Effects for ESA Interplanetary Missions
Abstract
This paper describes the architecture and the main features of the command emulators developed to support the Mars Express (MEX), Smart-1 and Rosetta missions within the Flight Dynamics (FD) Division at the European Space Operations Centre (ESOC). FD emulators are used to precisely model the spacecraft (S/C) dynamics and the behaviour of the Attitude and Orbit Control and Measurement System (AOCMS) of the S/C in order to: • Validate operational telecommands sent to the S/C • Generate high precision telemetry test data for FD internal system tests • Troubleshoot AOCMS anomalies and perform AOCMS analyses and studies The architecture and wide functionality of the FD emulators are detailed, describing how the actual software (s/w) is able to meet the needs. Commonalities and differences between different mission specific implementations are enlightened. The different fields of application of emulators within FD are illustrated. Finally, as an example of application, emulation results are shown, corresponding to the Rosetta asteroid fly-by mode (AFBM) test that will take place around the first Earth swing-by. Keywords: emulation, S/C dynamics, interplanetary missions, telecommands generation, end-to-end consistency check, telemetry generation, asteroid fly-by
