First micro satellite designed and built in Turkey: RASAT
RASAT is the second remote-sensing satellite after the launch of Turkey’s first remote
sensing satellite BiLSAT of TÜBİTAK UZAY. RASAT, having a high-resolution optical
imaging system and new modules developed by Turkish engineers, will be the first
Earth-observation satellite to be designed and manufactured in Turkey.
First micro satellite designed and built in Turkey: RASAT
RASAT has been operational since the day of launch -17th of August,2012.

RASAT is the second remote-sensing satellite after the launch of Turkey’s first remote
sensing satellite BiLSAT of TÜBİTAK UZAY. RASAT, having a high-resolution optical
imaging system and new modules developed by Turkish engineers, will be the first
Earth-observation satellite to be designed and manufactured in Turkey.

MISSION:
  • To improve know-how from design phase to in-orbit commissioning phase of a satellite project gained from BiLSAT Project,
  • To develop space qualified systems using currenttechnologies and gaining flight heritage bysucceeding in operating these systems in space,
  • To meet the requirements of Turkey in the sense of remote sensing as much as possible,
  • To investigate the current capabilities of Turkey for space technologies and to use as much as possible,
  • To increase number of qualified man power in the field of satellite technologies,
  • To meet the requirements of Turkish space industry through development of critical modules,
  • To prove the space-based capabilities of TÜBİTAK UZAY to Turkey and the World.
