The invention relates to a method for correcting zero drift of an MEMS (Micro Electro Mechanical Systems) gyroscope, which comprises the following steps: projecting azimuth angles and pitching angles in a frame coordinate system at a moment t and at a moment t+delta t into an inertial coordinate system by space coordinate transformation; then calculating to obtain a drift angular velocity at an interval of time delta t; and summing the drift angular velocity and an angular velocity of a frame in the inertial coordinate system, which is measured by the gyroscope, so as to obtain the corrected angular velocity of the frame. The method has the benefits that a stable and high-accuracy sensor in a system is utilized to correct zero drift of the MEMS gyroscope; and the correcting effect is obvious. The method is mainly applied to the field of moving carriers and the like. The method is completed mainly by software and is low in hardware cost.
