Are the Deep Space Network improvements being made for Galileo usable by other projects?
Not all, but several are. Mars Pathfinder, Mars Global Surveyor, and Pluto Express have all expressed interest in the telemetry subsystem being developed for Galileo. The ultracone is usable by any spacecraft which transmits in S- band. It is also fair to say that Galileo’s emphasis on data compression and encoding has spurred new research and development which is leading to the incorporation of sophisticated data compression schemes on projects under development.
