Automatic Tracking Satellite Dishes are satellite dishes used while a vehicle, boat or ship is in motion. Automatic tracking satellite dishes utilize gyroscopes, GPS position sensors, and uses unique satellite identification data and an integrated DVB decoder to aid in identification of the satellite that it is pointing at.
The dishes consist usually of stepper motors to drive and aim the dish, gyroscopes to detect changes in position while the vehicle is in motion, a parabolic reflector, low-noise block converter, and control unit.
They can use also shifted Phased arrays. (example: Starlink Dish).
