[COMET SCA] Webinar on Star Trackers

About this event

Robustness tests on star trackers require a closed-loop system allowing to stimulate the device with a false sky and play different scenarios including various perturbations. These on-ground tests enable to gain confidence in what the datasheets exhibit and often lead to better robustness from what is given by the manufacturer. This robustness makes it possible to consider star trackers use in survival modes, thus offering a simpler ACOS architecture. However, for missions with much higher accuracy needs, it is needed to have high accuracy star trackers.

Agenda :

  • 9h-9h45 : Robustness and closed-loop tests presentation on various star trackers by ADS
  • Use of STR in survival mode
  • 9h45 – 10h15 : On-going ESA/ADS study presented by ADS

// BREAK 15 minutes //

  • 10h30 – 11h : SHM on Spacebus NEO presented by TAS
  • 11h – 12 h : ASTRO XP high accuracy star tracker presented by Jena Optronik

The Communities of Experts federate the different spheres of expertise used in the space field through networks. Created by CNES in 1998, there are currently 20 communities bringing together more than 3,000 experts from the academic, industrial and institutional fields.
