It's possible that this just improves the baseline. Some sensors will
still be better than others, and unless sensor tech improves to the
point where perfect coverage is possible with very cheap sensor
drones (i.e., stealth techniques don't improve at the same rate - which
isn't entirely improbable) some directions will be less well scanned
than others, especially where a small colony world is concerned which
isn't expecting trouble.

How about sticking them in the same orbit as the main world, at
the 3 Lagrange points (L3, L4, L5)? That would give similar coverage
I would have thought.

Be seeing you,
