Abstract

This talk will present the architecture, operations philosophy, and plans for the array-based DSN.


For the last 45 years, JPL has provided excellent support for the space missions of NASA and its international partners, through the Deep Space Network (DSN). The DSN is structured around three Deep Space Communications Complexes (DSCCs) with large monolithic antennas in Australia, Spain, and the Western USA that provide 24x7 support to the missions in the S- and X-bands. There is also an emerging downlink capability at Ka-band. With the increasing need for higher data rates and the emphasis on cost-containment, JPL and NASA are exploring an architectural and implementation plan to increase the data rates by factors of 1000 or more in a cost-effective manner. As part of this strategy, the array-based DSN will:


  • Be cost-effective to build and deploy.
  • Have a G/T that is x10 that of the G/T of the 70-m antenna subnet at X-band.
  • Be fully Ka-band capable (another x4 factor in data rate), including weather immunity.
  • Have an O&M cost that is less than half of today's O&M cost.

The Speaker

Joe Statman joined JPL in 1980 upon receiving his M.Sc. from UCLA and completing undergraduate studies in Israel. Since then, he has served in a variety of technical and management roles in the telecommunications and navigation areas. Before his present role, his most recent assignments were leading the team that developed the ground system to support the Galileo S-band mission, managing the Communications Ground Systems Section, and managing the DSMS Engineering Program Office.
