, 03:06, 3 May 2016→OCSD-2 (A/B): Removed reference to sat to sat communications
What follows is a high level overview of notable milestones in the development of space-based optical communications.

After lock on had become routine, LADEE was loaded with predefined instructions to turn on the LLST system. Then when LADEE next came into view, without any RF communication, the LLST system was activated and locked on to the ground.The entire windows was then operated entirely upon optical commands, and RF was never used.

OCSD-2 is scheduled for launch during 2016 aboard a currently unidentified Falcon 9 launch from Vandenberg AFB. The first such launch is currently scheduled for July. OCSD-2 contains the remaining two of the three planned satellites, which will launch as a single 3U unit and separate into 2 independent satellites. The OCSD-2 A and B payloads will attempt satellite-earth and satellite-satellite communications at speeds in excess of 500 Mbit/s, with the primary purpose of demonstrating technologies for satellites operating in proximity to each other. It is unclear what systems will differ between the OCSD-1 and OCSD-2 payloads.
