They don't "do" anything but draw circles on the map.  The feature was primarily
put in place for use in search and rescue, where the circles are meant to 
denote regions of probability.  It's a common tool used to limit the search
area to those distances within which subjects of the type being looked for 
are usually found.  Such distances are tabulated for different types of 
subjects.

The objects created like this would show up on all the Xastir instances in 
use on the search, getting important mission information to everyone involved.
And obviously, to those who are not.
