About me[edit]

I worked 36 years as a mathematician in European Space Operations Center developing concepts, mathematical algorithms and software for the orbit design and control of low Earth (ERS-1,ERS-2, Envisat), Geostationary (Meteosat, ECS), and Interplanetary spacecraft (Giotto and Ulysses). And for space telescopes in highly eccentric orbits (XMM-Newton, INTEGRAL)

COSE is in fact ESOC backwards!
