The paper describes the operations of ESA's Optical Ground Station during the Lunar Laser Communications Demonstration experiment with NASA's LADEE spacecraft in October and November 2013. The study aims to present two improved OGS designs under a new industrial contract and test them in a follow‑up laser communication campaign scheduled for March 2014. The OGS telescope’s transmitter and receiver are geometrically separated to avoid cross‑talk, and the study details the development of the two new designs that will be evaluated in the upcoming campaign. The paper reports that the initial arrangement was unstable in alignment, outlines the problems encountered, and describes the solution that was implemented.
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.
