The invention discloses an auxiliary positioning method in an unbelief channel environment, a sound source module installed in intelligent equipment sends out a first sound wave positioning signal, and when a sound source detection module installed on target equipment does not receive the first sound wave positioning signal, the intelligent equipment sends out a second sound wave positioning signal; after the auxiliary equipment receives the direct second sound wave positioning signal, a third sound wave positioning signal is emitted through an installed emitter, a sound source detection module of the target equipment receives the direct third sound wave positioning signal, and relative coordinates (x, y, z) of the target equipment with the intelligent equipment as a reference object are obtained; by judging the channel state, activating the auxiliary equipment when the channel is in the non-confidence state, and secondarily positioning the target equipment by using the auxiliary equipment as a relay port, th
