KOMPSAT-3 – Optical Ground Support Equipment
Designed 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
