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=E2=80=99s field - see&=23160;https= ://leolabs.space/radars/&=23160;

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

Profession Hugh Lewis follows Starlink=E2=80=99= 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 o= f radars which track anything larger than 10cm in cross-section, and prov= ides an awesome visualization here:

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. :-)<= br />
