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 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 & 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.



  • 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.

Optional Instruments:

  • Lasers for Satellite Laser Ranging
  • Event timing systems (to picoseconds)
  • Imagers: Electron Multiplied Charge-Coupled Device (EMCCD) and back illuminated Charge-Coupled Device
  • Spectrometers
  • Wide field imagers optimised for sensitive space observation low earth orbit (LEO) to high earth orbit (HEO)
  • Wide field correctors
  • Integrated to control system

Optional Accessories:

  • Instrument rotators
  • Instrument cubes
  • Hexapod
  • Fast Tip / Tilt secondary mirrors
  • Filters
  • Auto-guiders
  • Mirror temperature conditioning
  • Cable Handling

Telescope construction is between 12 and 24 months depending on the size of the aperture and the installation location.

Examples of our work:

  • SALRO mobile telescope deployed in Riyadh, Saudi Arabia. (1995)
  • University of Tokyo 2m telescope and enclosure, also known as the MAGNUM telescope (Multi-colour Active Galactic Nuclei Monitoring) installed at Mt Halakea, Hawaii. (1998)
  • 2m telescope and enclosure installed in the Himalayas for the Indian Institute of Astrophysics. (1999)
  • Four 1.8m Interferometric Telescopes for the California Astronomical Research Association (also known as the Keck Outrigger design). (2000)
  • Advanced Planet Finder (APF) 2.4m telescope and enclosure for University of California (also known as the Lick Observatory). (2006)
  • Panstarrs 1.8m telescope and enclosure for the University of Hawaii. This telescope drew upon the strengths of the 1.8m Keck Outrigger and the 2.4m APF Lick telescopes. (2006)
