The determination of satellite clock offset is limited by the shot noise limit of classical measurement, and the accuracy of clock offset measurement is only on the order of ns. Based on the urgent demand for high-precision time reference in the military and civilian fields, a satellite clock offset measurement scheme based on dual-channel six-delay conveyor belt quantum entangled light is proposed, and the proposed scheme is based on the conveyor belt protocol. First, the frequency entangled optical signal is prepared by spontaneous parameter down-conversion. Then, the second-order correlation detection solution of the frequency entangled optical signal is carried out by using the HOM (Hong-Ou-Mandel) interferometer to obtain the clock offset information. Finally, the influence of related parameters on the clock offset measurement is simulated and analyzed. The proposed scheme does not need to measure the arrival time, is not affected by the dispersion effect and the distance between the satellite and the ground , and can theoretically realize satellite offset error measurement of the order of ps.
