Ka-band mobile and personal systems development at JPL

Abstract

Expanding the commercial applications of space is one of the primary goals of NASA. Throughout the eighties NASA has pursued this objective by sponsoring and undertaking the development of system concepts, enabling high risk technologies, and actual proof of concept demonstration hardware. In the mobile and personal arena, or the so-called low data rate applications area, JPL is NASA's lead center. JPL's focus of activities has been the Mobile Satellite-Experiment (MSAT-X) project, which developed mobile communication technologies at L-band, and its present successors, which aim to expand the mobile arena by exploiting Ka-band.
