The research described in this paper was performed primarily at the
California Institute of
Technology
and at the Center for Space
Microelectronics Technology at the Jet Propulsion
Laboratory
. It has been sponsored by the
National Aeronautics and Space
Administration
, Office of Advanced Concepts and
Technology, under grant BK-509-20-42-00-00. The
W. M. Keck
Observatory
is operated as a
scientific partnership between the California Institute of Technology
and the University of California. It was made possible by the
generous gift of the W. M. Keck Foundation, and the support of its
late president, Howard Keck. We also wish to thank Jimi Patel and
Carl McFadden, our ground station operators at JPL and
Tripler Army Medical
Center
, respectively, and Jon Chock,
the Keck Observatory Systems Administrator, for their crucial
assistance for the entire duration of this project. The scheduling
and operations staff for ACTS have been extremely accommodating as
well.
