Patent ID: 6965471

Claim:
An astrometry system comprising an astrometry first telescope having first and second sightlines respectively corresponding to first and second fields of view, a first star detector system in a first focal plane, first optical means adapted to combine first and second light beams from stars in said first and second fields of view and substantially parallel to said first and second sightlines and deliver them to said first star detector system, a second telescope having a third sightline substantially parallel to one of said first and second sightlines, a second star detector in at least one second focal plane, second optical means adapted to collect a third light beam from said stars substantially parallel to said third sightline and deliver it to said second star detector, and processor means adapted to determine the source field of view of each star detected as a function of whether it is detected either by only said first detector or conjointly by said first and second detectors.
