The instruments are what LeoLabs operates - curtain phased-array radars in various places, which detect and measure objects in orbit as they pass through the curtain’s field - see https://leolabs.space/radars/<https://urldefense.com/v3/__https://leolabs.space/radars/__;!!P7nkOOY!q8Arz3UDWiNlKOeNBmYNjSeER74Lye313jqr09DqZhKtMQsgspbU3q6isYZCywvVLpEh6xheI5cDl8v5n_nNa700Fw$>

They then offer conjuction analysis and warnings to satellite operators under contract, based on their catalog of objects and debris.

Best,

Mike

Great visualization. Dumb question but I can’t figure it out. What are the orange planes labeled “instruments”? They are obviously related o the beams below them but I’m not sure what they are either.



Thank you

Profession Hugh Lewis follows Starlink’s conjuction reports closely, and writes very detailed threads whenever a report comes up:

If you want an idea of -what- they are avoiding, LeoLabs operates a set of radars which track anything larger than 10cm in cross-section, and provides an awesome visualization here:

(make sure to enable the “debris” checkbox too)



Best,

I think the main point of the article is that the amount of maneuvers
needed is currently increasing exponentially:

Indeed, I read that. But the article does not explain why they think
this trend will continue exponentially.

Obviously it can't continue exponentially forever, because eventually
all satellites are on the move evading one another 100% of the time. :-)
