    TMO Progress Report 42-138 August 15, 1999Progress in Design and Construction of theOptical Communications Laser LaboratoryK. E. Wilson, 1 M. Britcliffe, 1 and N. Golshan 1The deployment of advanced hyperspectral imaging and other Earth sensinginstruments onboard Earth observing satellites is driving the demand for high-data-rate communications. Optical communications meet the required data rates withsmall, low-mass, and low-power communications packages. JPL, as NASA’s leadcenter in optical communications, plans to construct a 1-m Optical CommunicationsTelescope Laboratory (OCTL) at its Table Mountain Facility (TMF) located in theSan Gabriel Mountains of Southern California at an altitude of 2.29 km. Thedesign of the building has been completed, and the construction contractor hasbeen selected. Groundbreaking is expected to start at the beginning of the 1999TMF construction season. A request for proposal (RFP) has been issued for theprocurement of the telescope system. Prior to releasing the RFP, we conducteda request for information with industry for the telescope system. Several vendorsresponded favorably and provided information on key elements of the proposeddesign. These inputs were considered in developing the final requirements in theRFP.I. IntroductionThe successful bidirectional space-to-ground optical communications demonstrations conducted withthe Japanese Engineering Test Satellite (ETS-VI) [1,2] will be followed by a series of turn-of-the-centuryspace-to-space and space-to ground demonstrations at data rates ranging from 2 Mb/s to 2.5 Gb/s[3–6]. To support its future optical communications demonstrations, NASA is building a 1-m OpticalCommunications Telescope Laboratory (OCTL) transceiver station at its Table Mountain Facility inthe San Gabriel Mountains of Southern California [7]. TMF is at a 2.29-km elevation and has typicalatmospheric seeing of 1.5 to 2.0 arcsec. The telescope is designed as a multipurpose telescope; however,the OCTL’s principal function is to support NASA’s optical communications technology developmentand demonstrations. Consequently, the key requirements of the station are to(1) Conduct communication experiments and demonstrations with laser-bearing spacecraft fromlow Earth orbit (LEO) to deep space, with an emphasis on deep-space telemetry.(2) Develop optical spacecraft communications technologies, with an emphasis on deep-spaceapplications, by conducting ground-to-ground, ground-to-LEO, and ground-to-deep-space ex-periments.1 Communications Systems and Research Section.1
