Has anybody tried tiny commercial space stations as sensor pickets?
Thinking about the problem of how to provide long-term sensor presence with low ongoing costs. Obviously these stations would have very limited capabilities since they are limited to commercial sensors, but they also should be very cheap and small, and you could probably carry them in a hangar to drop at points of interest.
Unless you're going for deep space locations DST installations are probably the regular way of handling this problem. However, a tiny picket station could be easier to transport.
