We review the current applications base for the use of free-space optical communications technology. We then describe the NASA programs in the optical communications area addressing those applications areas. In particular, we describe the Laser Communications Demonstration System, an industry-driven program for the space-demonstration of this technology at data rates of at least 750 Mbps. We then describe NASA technology development and study activities in support of these applications. Activities described include the Optical Communications Demonstrator, a study of an air-to-ground system demonstration, a mission application study for the TOPSAT radar mapping mission, and a program to acquire detailed statistics on atmospheric transmission for space-to-ground links. |
