I'm not suggesting that "IP spacecraft" should be an actual
engineering term. I used the phrase as shorthand for "a
spacecraft using IP protocols over their communications
links." The project is currently not planning to use IP
protocols in anyway over the RF links. I don't know if they have
any IP over the spacecraft bus itself.<br><br>
I think the information I forwarded from GPM is useful to the group,
since it shows how one LEO Earth Science flight project thought they
could use IP protocols for all of their communications needs. It
may provide a good starting point for discussions.<br><br>

Dave: do you have a clear, crisp engineering definition of the
characteristics of "an IP spacecraft"?<br><br>
