OGS Installing Graz
ASA OGS in ÖAW Graz
The ASA OGS has landed in Graz (Austria) on the ÖAW building. After 80 min the AZ800 f6 RC and dome have been ready to work.
ASA OGS in ÖAW Graz
This OGS was the result of an design process
between the customer (IQOQI) and ASA.
The requirements include a mobile usage and a transportation with an helicopter. The result was the ASA OGS 800. It fits into a 20ft (6m) container. The realizations of this project we uas a baseline for the ASAEYE.

- Special optic design AZ800 f6, main mirror f2
- Mobile solution for QKD terminal with adaptive optics(AO)
- Test station for Satellite laser ranging SLR (ÖAW-IWF Graz)
