ESA/IPC(2010)81beyond the current European state-of-the-art in Navigation, Guidance and Control technologies. The characteristics, inparticular the GNC performance and autonomy requirements, of a NEO sample return mission require an increase inmaturity of the GNC technologies. The TRL objective, 5-6 by 2011, can only be achieved with a close synergy with theAurora technology programme in particular for the key descent and landing phases.In this respect, several past and on-going GNC activities which are directly relevant to the present proposal are listedbelow. Past technology activities were conducted in preparation of the ROSETTA mission, such as the -Autonomous andAdvanced Navigation Techniques- (AANT) study which investigated and evaluated autonomous GNC/FDIR strategiesand concepts applicable to a wide range of interplanetary missions, while the most recent ones are part of the AURORAprogramme. These technology activities deal in particular with the development of an Engineering Model of a multimission(landing, rendezvous, cruise, mobility) optical camera suitable for NEO missions (TRL: 5-6 by 2011) and theassociated Image Processing (IP) algorithms and optical stimulator for the verification and validation of vision basednavigation systems (ViSOS), and the development of hazard mapping and re-targeting functions (TRL: 4-5 by 2009).Also, in support of several vision-based navigation system activities, the Agency has funded the development of a terrainsimulation tool, namely PANGU for Planet and Asteroid Scene Generation Utility, which is capable of synthesizing theterrain of planets and asteroids realistically. In addition, the tool has been extended to provide radar signal return from asmall body. This asset is fundamental to the validation of the objectives of the proposed activity.References- ESA Contract No. 14320 (CCN2), -Tool for Terminal GNC Design for NEO Impactor Impactor Missions (CLEON)-focusing on the development of a software tool for GNC performance assessment in the terminal phase of a NEOImpactor mission- ESA Contract No. 1946 (CCN1), -Autonomous GNC Design for NEO Rendezvous (CLEON+)- focusing on thedevelopment of a software tool for GNC performance assessment in the terminal phase of an autonomous NEOrendezvous mission- ESA Contract No.17338 (CCN3), -Asteroid and Whole Planet Simulation with PANGU- dealing with asteroid craterand irregular lighting conditions modelling- ESA Contract No. 9558, -Autonomous and Advanced Navigation Techniques (AANT)- focusing on autonomousGNC/FDIR strategies and concepts applicable to a wide range of interplanetary missions- ESA Contract No. 15292, -Autonomous Navigation for Interplanetary Missions (AutoNav)-, focusing on theinterplanetary phases- ESA Contract No. 20528, -Optical Flow Navigation system for Landing-, focusing on the final powered descent phaseand involving 3D landmarks matching- ESA Contract No. 156188, -Navigation for Planetary Approach and Landing (NPAL)-, focusing on the development ofa vision based camera breadboard with features extraction capability- ESA Contract No. 18038 (CCN3), -Hazard Avoidance Consolidation Activities-, focusing on the development of hazardmapping and re-targeting functions- ESA contract No 20848 -Multi-purpose Vision-based navigation sensor architecture definition (VisNaV)- dealing withthe detailed design of a multi-mission optical navigation camera suitable for landing, rendezvous, cruise/fly-by andmobilityDeliverablesSW (prototype)HW EM (synergy with Aurora programme)ApplicationCurrent TRL: 2-4 Target TRL: 5-6TRL 5 by Q4 2011Need/Date:ApplicationMission:S/W Clause:GenericOperational SWConsistency with Harmonisation Roadmap and conclusion:N/AContractDuration:Reference toESTER18T8071Page 60 of 60
