The invention discloses a telescopic mechanism for three-dimensional attitude pointing of a Wiener satellite. The invention relates to a telescopic mechanism, and aims to solve the problems that in the prior art, micro-nano satellite attitude control is high in cost and large in power consumption, and the increasing requirements of on-orbit load multi-task, low power consumption, low cost, light weight and capability of ensuring system safety and reliability by utilizing minimum resource configuration cannot be met. The device comprises a gravity gradient telescopic rod, a telescopic rod driving mechanism, a transmission mechanism, a driving motor assembly and a shell, one end of the gravity gradient telescopic rod is installed on the Wiener satellite through the shell, the telescopic rod driving mechanism is installed in the gravity gradient telescopic rod, the other end of the gravity gradient telescopic rod is fixedly connected with the eddy current damping ball, the transmission mechanism is installed on the gravity gradient telescopic rod, and the driving motor assembly is connected with the transmission mechanism and drives the transmission mechanism to rotate. The method is applied to the field of spacecraft control.
