It's not a gimbal, it's a set of stepper motors and gears. It's not designed for constant movement or tracking. The current starlink terminal is a dual beamforming phased array that will align itself to have its flat face oriented towards the area above you that has the highest simultaneous density of satellites at any given point in time. Beta terminals in north WA state, for example, are angled about 10 degrees off flat, looking slightly north.

In fact a current starlink terminal (which has a 6-axis sensor and GPS receiver built into it) will turn itself off if it detects movement. The terminals for things like yachts are not available to the public yet, though I have no doubt they're in the works.
