NASA is presently overseeing a project tocreate the world’s first free-space lasercommunications system that can be operated overa range ten times larger than the near-earth rangesthat have been demonstrated to date. To be flownon the Lunar Atmosphere and Dust EnvironmentExplorer (LADEE), which is planned for launch byNASA in 2012, it will(More)
The Lunar Laser Communications Demonstration represents NASA's first attempt to demonstrate optical communications from a lunar orbiting spacecraft to an Earth-based ground receiver. A low size, weight and power optical terminal will be integrated onto the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft, presently scheduled to launch in(More)
The Lunar Laser Communications Demonstration (LLCD) is an ongoing project to demonstrate a high-rate, bidirectional optical communications link between a lunar satellite and an Earth-based ground terminal. The optical downlink operates at data rates up to 622 Mbps and employs photon counting array receiver technology. While the use of a 16-PPM modulation(More)
