dual spin




A spacecraft design in which the main body of the satellite is spun to provide altitude stabilization, and the antenna assembly is "de-spun" – in other words, rotated at the same speed but in the opposite direction – by means of a motor and bearing system in order to continually point the antenna earthward.
