His research has been on astrometry, i.e. the measurement of positions, motions and distances of stars., and since 1960 he has developed photoelectric astrometry.
He designed the ESA satellite Hipparcos in 1975, and proposed in 1981 a new experiment on Hipparcos resulting in the Tycho-2 Catalogue of the 2.5 million brightest stars.
In 1992 he proposed a new satellite Roemer, where the use of CCDs meant 100,000 times higher efficiency than with Hipparcos. This resulted in the adoption of a new ESA satellite, Gaia, to be launched in 2012.
