22 February 2012Overview and status of the Lunar Laser Communications Demonstration
The Lunar Laser Communications Demonstration (LLCD), a project being undertaken by
MIT Lincoln Laboratory, NASA's Goddard Space Flight Center, and the Jet Propulsion
Laboratory, will be NASA's first attempt to demonstrate optical communications between a
lunar orbiting spacecraft and Earth-based ground receivers. The LLCD space terminal will
be flown on the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft,
presently scheduled to launch in 2013. LLCD will demonstrate downlink optical
communications at rates up to 620 Mbps, uplink optical communications at rates up to 20
Mbps, and two-way time-of-flight measurements with the potential to perform ranging with
sub-centimeter accuracy.
