The Carlsberg astrometric telescope has been operating since 1984 at
the international observatory of the Roque de los Muchachos on the
island of La Palma in the Canaries. It is at 28.7 deg N and at an
altitude of 2400m, and is operated jointly by Copenhagen University
Observatory, the Royal Greenwich Observatory and the Real Instituto y
Observatorio de la Armada en San Fernando.

Absolute astrometry is carried out nightly on objects in the outer
Solar System. In the period 1984-94 about 20 000 observations has been
made. These include observations of about 60 minor planets.

The absolute positions of the major planets are compared with recent
integrations of the JPL series DE-, and plots of the residuals and a
discussion of the observational errors are presented.

Future developement of the Carlsberg astrometric telescope and its
programme of Solar System observations are reviewed.
