A base station includes a base station body and a base station addressing device. The base station addressing device includes: an acquisition module configured to acquire satellite observation data at a current observation point; a calculation module configured to evaluate the observation quality at the observation point according to the satellite observation data; and an output module configured to output a first prompt according to the observation quality, where the first prompt indicates the suitability of the observation point for mounting the base station. The base station addressing device is detachably connected to the base station body so that the base station addressing device is capable of being detached from the base station body to perform an addressing task.
