KOMPSAT-3 – OGSE

KOMPSAT-3 – Optical Ground Support Equipment

kompsat_ogrse_thales00Designed and manufactured to test the optical telescope also manufacture by TSESO in ambient and vacuum conditions. A 9 meter support bench with a 1 meter diameter collimator and a 1 meter diameter mototrized mirror for autocollimation are the main pieces.

A complex multidisciplinary project

Here is a list of the main systems to be provided:
- A 9 meter optical bench
- A large Cassegrain Collimator for optical testing purpose
- A 1 meter diameter and motorized autocollimator
- Motorized payload support system
- Focal plane instruments (motorized stages, integrating sphere, filters, monochromator)
- Air cushioned conveyor
- Optical windows for vacuum chamber
- Vibration free system to protect the optical system
- Temperature monitoring system
- Command/control software for the positioning of the components

Thales SESO Efficiency

It only took 2 years to design, manufacture, test and deliver all the components of this massive project. It was delivered in September 2008

Wolrd class performances

2 Large mirrors of 1m (flat and concave) made in Zerodur™ for virtually no thermal expension.
Extremely low wavefront error (26nm RMS for the collimator and 9nm RMS for the autocollimator)
Minimal weight: lightened mirrors up to 80% its original weight

Results in the most modern optical laboratory in Asia
