US Patent 11981450 Torque control for balloon coupling

Aspects of the disclosure provide for controlling orientation of a payload of a balloon through a despin mechanism. In one instance, a system may include a flexible coupling configured to reduce effects of a balloon envelope tilting on a payload, a sensor configured to measure rotational displacement of the flexible coupling, a despin mechanism including a motor configured to rotate the payload, and a controller. The controller may be configured to use receive the measured rotational displacement and to use the despin mechanism to rotate the payload towards a preferred orientation based on the measured rotational displacement.
