EOS is an established supplier of telescopes and observatory systems to the world market. EOS designs and manufactures state of the art alt-az telescopes of the highest quality and technical performance as imagers, beam directors and trackers– they are smooth at high speeds, highly accurate, reliable, robust and low maintenance. The design offers seamless integration of the telescope, telescope enclosure, instruments and software programs which are fitted with remote diagnostic support, automated operation and are easily upgraded.

Telescope Applications:

  • Astronomy and Optical Interferometry
  • Satellite Laser Ranging
  • Optical Communications
  • Space Object Classification
  • Space Debris Mapping
  • Laser Beam Directors

EOS telescope gimbals are manufactured in either modular (standard) or custom designs:


  • 1 metre: can be used for apertures up to 1.4m
  • 2 metre: can be used for apertures from 1.8m to 2.4m


  • Custom telescopes can accommodate apertures of up to 6.5m.

As laser tracking grade instruments, sky accuracy of less than 2.5 arc sec rms is standard in useful sky zones, and tracking smoothness of 0.1 arc sec rms is achievable. Our solutions can include mobile systems for laser ranging with integral solar power and satellite communications for remote operation.
