I'm peeking in MegaT, and a Grav Parachute runs 2500cr and is TL10 To me, a cubesat with an unfolding solar panel and a cheap grav module along the lines of the above makes sense for comm relays. The whole thing would pack down to about 15 liters if you figure the solar panel is the size of a parachute, so you'd be packing quite a few of them in one kiloliter of a Type-S's equipment bay, and it sounds like just the tool for the job. It's only got to stay in orbit a week or so for the survey anyway. Or, you could go the other way. Check out: https://en.wikipedia.org/wiki/KickSat I can picture the IISS having a "Spreader-sat" the size of a 2 liter coke bottle that is in a fairly fast ball of twine orbit, and has oodles of chipsats in launchers all over the outside of it. Drop one in orbit, and it uses the launchers to pop one off every few minutes to cover the planet. The chipsats would use mesh radio to relay from one to another until the message got to the ship. I can see the desire to add a player complication, or 'realism', but after 3000 years of space operations, I'd think that what Early 21st Century Terra calls "realism" and what 1100's Sylea calls "realism" are two very different things.
