Abstract
The paper describes the operations of ESA’s Optical Ground Station (OGS) during the Lunar Laser Communications Demonstration (LLCD) experiment, performed in October and November 2013 with NASA’s Lunar Atmospheric and Dust Environmental Explorer (LADEE) spacecraft. First the transmitter and receiver designs at the OGS telescope are described, which are geometrically separated to prevent cross-talk. Problems encountered and the lesson learned will be explained. As it turned the chosen arrangement was not sufficiently stable in terms of alignment and the paper will describe the solution found. A new industrial contract has been placed for improvement of the design of two solutions will be presented, which will both be tested in a follow-up laser communication campaign, scheduled for end March 2014.
