The present invention relates to an angle zero position memory method based on laser distance measurement. A laser distance measurement method is employed to synchronously collect a distance measurement value and an antenna angle, a laser emitter is fixed in a housing, unoccupied portions in the housing are filled with foam filling agent to ensure damping and fixing effects, and a reflector fixedon a rotary table is rotated to ensure that the laser of the laser emitter can radiate to the right place. In a condition that the laser emitter is electrified, the antenna is rotated, distance measurement data of a data processing unit is observed, when big change of data occurs at the first time, the rotation speed of the antenna is reduced, and when big change of data occurs at the second time,a current angle is recorded, namely an angle zero position; a mode of real-time and later data comparison is employed, the same interruption and the same B code are used to ensure the time consistence, and a corresponding angle is antenna zero position at the moment when the big change of the data occurs at the second time. The angle zero position memory method based on the laser distance measurement is convenient to implement, has an angle zero position memory function and has a very high application value.
