> B. You could have multiple panels operate as a swarm.

Is that level of precision even remotely achievable with today's technology?

My understanding is that orbital insertion accuracy is in the ±10-50 meters range, with the most advanced formation flying satellite swarms hitting 10 cm to 1 m precision between satellites with the help of optical navigation.

But the precision between the panels on a telescope like JWST is in the sub-mm range, no?

Also, I'd assume stuff like orbital decay, atmospheric drag, gravitational perturbations, and solar radiation pressure would make it difficult to maintain precision over time.

I'm sure/hopeful there's some people here at HN working on stuff like this, please fill in and correct me!
