Telling stories
Natal Workshop October 30th , 20043
The Story
The Inheritance Stellar seismology is recognized as a priority : Scientific Prospective
Workshop (Deauville, 1985) Study of the Sun
Ground observation IPHIR (Phobos mission) GOLF (Soho mission) EVRIS (Mars-96)
The Birth Scientific Prospective Workshop (Saint-Malo, 1993) The Search for extra-solar planets did join the program
The Maturation 1993-1999 Phases 0, A & B
The difficult starting 1999-2003 COROT in the frame of the « Faster & Cheaper » scientific missions based
on the PROTEUS bus (Jason-1, Calipso, Corot, Smos, Jason-2)

A long story
Natal Workshop October 30th , 20045
The PROTEUS Bus
PROTEUS is a multi-mission platform European standard
Qualified for all LEO missions
500-600 kg satellite class, 1m3 volume (bus)
Typical payload envelope: 300kg, 300W
PROTEUS flight domain
Any orbit in the 700-1500 km range
Precise 3-axis attitude control
Compatible with available small-medium launchers
And an associated generic Ground Segment
PROTEUS stands for : «Plateforme Réutilisable pour
l’Observation, les Télécommunications Et Utilisations Scientifiques»

Cooperation
Cooperation is the main feature of the COROT organization
Cooperation makes the management more difficult, the relationship being based on « the best effort » of each party
Cooperation makes more technical interfaces to handle at system level
So, why looking for cooperation ?
Cooperation has been mandatory to re-start the program in 2000/2001
Cooperation increases the ressources (more funds, more manpower)
Probably the most important, Cooperation makes the project stronger from the human being prospecpective
By very fruitful exchanges of engineering practices, ways of work and simply cultures
By giving to this mission an international dimension

The Present
The project is a hive of activity ~15 (successful) reviews within the last 10 months
The System and all components are under development The System: The System Interfaces Review is coming The Ground Segment : Mission Centre Design & Customization of
the Proteus standard Control Centre The Satellite : The Flight Model of the Proteus Bus is under
integration The Instrument : the Flight Model is under integration (EMI/EMC
tests are starting) The Launcher is ordered (Soyuz from Baïkonour)
Everything is on-time for a Launch at Baïkonour (Kazakhstan) planned during the Summertime of 2006 (June is targeting)
The funding is nominal

The 2005 Milestones
Next Wintertime Start of the final integration of the instrument in Toulouse System Interfaces Review
Springtime Satellite CDR Preliminary Launcher Mission Analysis Review
Summertime Acceptance tests of the Instrument Earth Terminal (TTCET) delivery in Natal Ground segment Integration Start of System Compatibility tests
In the Fall Delivery of the Instrument for Flight Satellite Integration System Validation
Natal Workshop October 30th , 200414
Status in short
A strong acceleration of the project
The flight hardware is under manufacturing, integration & test
The System activities are on time
The Ground Segment and the preparation of the Operations are on time
The launcher is ordered
The COROT mission is in a good shape
Natal Workshop October 30th , 200415
The Short in short
The working days are very long and by the same time very short
The COROT mission is still leading the race
The COROT project is vey happy to work with BRASIL
The life is beautiful (particularly in NATAL)
