The invention relates to a forwarding type GNSS dynamic measurement accuracy testing and evaluating method, which comprises the steps of selecting a real motion carrier of a GNSS measurement system to be tested to act as a motion testing platform, building a satellite navigation signal forwarding environment on the motion carrier by using a satellite navigation signal repeater, and enabling real-time position information acquired by a mobile station of the GNSS measurement system to be tested and a comparative measurement receiver to be equivalent to a mounting part of a forwarding antenna; then designing a carrier motion environment, laying a reference station network, and enabling the comparative measurement receiver to be closer to a reference station so as to ensure acquisition of a position reference value with higher accuracy; acquiring a real-time position reference value of the mobile station of the GNSS measurement system to be tested under a time alignment condition by using test data interpolation
