According to a Spaceflight101 article on the ABS-3A communications satellite, attitude control is via reaction wheel: The 702SP satellite platform uses a pure electrical propulsion system that performs the insertion of the satellite from its transfer orbit into Geostationary Orbit, stationkeeping in the GEO slot and desaturations of the reaction wheels at ...

Reaction Control System Thrusters typically have a thrust on the order of Newtons to tens of Newtons – hundreds of Newtons for atmospheric control (e.g. the RCS thrusters on Falcon 9 have about 400 N). Ion Thrusters in current use have a thrust on the order tens to hundreds of Millinewtons. There are experimental thrusters that have achieved 5 N in lab ...

Fine metallic dust could not be stored and injected into the thruster within zero gravity. To inject a gas into an ion thruster is easy, just open a small valve only a little. If you try to blow the dust by a gas into the thruster, the dust particles will agglomerate at the valve and finally block it. Of course there are other reasons not to use dust for ion ...

There are some papers about the interaction of ion thrusters with the ionosphere, see: https://www.particleincell.com/2020/vleo-satellite-aerodynamics/ Simulations were done between 160 and 250 km. But the region 450 km and above was not studied. This image from the first paper shows a wake front shielding the ion thruster from the molecules of the ...
