yes, similar idea, but I'm pretty sure DSAC uses a cloud of ions, not a 
single one.

if you google for "Ely" and "Atomic Clock" you'll turn up a bunch of 
papers with Todd Ely in them - he's the PI for DSAC and sort of the 
"spacecraft clock" guy, particularly with respect to navigation and 
radiometrics (as opposed to radio science) - those papers will talk 
about how one might use a better clock in space.

Bob Tjoelker and John Prestage are the "ion clock" guys - if you want to 
know how the clock works.
