OCSD-1 was launched on October 8, 2015. OCSD-1 was the first of three planned satellites, carrying a 6W fiber laser with a 0.7° divergence half angle designed to downlink with a 30 cm ground telescope. This was later enlarged to 80 cm. [https://directory.eoportal.org/web/eoportal/satellite-missions/a/aerocube-ocsd] Projected data rates from OCSD-1 range from 5 to 100 Mbits/s. On October 30, 2015, NASA acknowledged that the Attitude Determination and Control System ([https://en.wikipedia.org/wiki/Attitude_control ADCS]) onboard the satellite is not functioning properly, preventing a test of the satellite's optical communications systems.[http://www.nasa.gov/feature/ocsd] OCSD-1 does not contain any fine beam steering systems, relying wholly on the ADCS for optical alignment. The stated minimum ADCS precision for basic link function is 0.15°; NASA and The Aerospace Corporation has claimed the optical link could achieve data rates above 1 Gbit/s with an higher precision ADCS.
