I believe the later PS3 motion controllers removed the magnetometers because they were causing more problems than they solved.

I must have steel beams in my floor or something, because while positional tracking was great with 4 cameras, rotation would either slowly drift, or just be a jerky mess and flip randomly depending on my position in the room.

PSMoveService has a bunch of different modes that behave differently, but I could never get a setup that was really usable.
