Abstract: This application provides a method for measuring an azimuth of a base station antenna. The method includes: obtaining angular velocity data measured by an angular motion detection apparatus that is stationary relative to a base station antenna, and obtaining a position relationship between a direction of a sensitive axis of the angular motion detection apparatus and a direction of a main lobe of the base station antenna; determining, based on the angular velocity data, a first position relationship between the direction of the sensitive axis of the angular motion detection apparatus and a true north direction; and determining an azimuth of the base station antenna based on the first position relationship and a second position relationship between the direction of the sensitive axis of the angular motion detection apparatus and the direction of the main lobe of the base station antenna.

Abstract: This application provides an antenna gearbox transmission mechanism and an antenna. The antenna gearbox transmission mechanism includes a drive shaft, a first transmission structure, and a second transmission structure. The first transmission structure includes a first driving gear and a first driven gear set, the first driven gear set includes at least one first driven gear, the second transmission structure includes a second driving gear and a second driven gear, and both are in a transmission connection to the drive shaft. The first driven gear set is in a transmission connection to a first antenna array phase shifter, and the second driven gear is in a transmission connection to a second antenna array phase shifter. The first driving gear meshes with the first driven gear set, and when the second driving gear moves, the second driving gear meshes with or separates from the second driven gear.
