SOCRATES or Space Optical Communications Research Advanced Technology Satellite is a Japanese micro-satellite launched in 2014. The satellite is purely a technology demonstrator intended to help AES company to gain experience in basic mission control, attitude control and spacecraft communications. Its main experiment is SOTA (Small Optical TrAnsponder), an optical small satellite communications demonstrator.[1] All subsystems of spacecraft are powered by solar cells mounted on spacecraft body and stub wings, with estimated electrical power of 120W BOL degrading to 100W EOL.[1][2][3]
Launch
SOCRATES was launched from Tanegashima, Japan, on 24 May 2014 at 03:05:00 UTC by an H-IIA 202.[4]
