I can say that they have multiple station keeping and orientation methods. The ion thrusters are public info!

There's been some interesting work on rigid body attitude control with sliding weights of late (as an alternative to gyros) - all fun stuff.

My main hope for internet satellites and other massive constellations is they all shutdown over radio quiet zones and ideally do something about being so shiny in the sun .. I'm a fan of radio astronomy and the night sky.

Fingers crossed. :-)

Can’t say more :)
