they would have to stay in very precise distances from each other over time Is this necessary, or do they simply need to precisely distinguish their relative position? My understanding of the JWT's not-perfectly-smooth lens is that the ability to measure (and correct for) its distortions vastly simplified the construction, and I naively think the same principle could be used in a swarm of satellites.
