Abstract：The inter-satellite laser interferometers have a longer interference arm (106km) than the ground interferometer and can detect gravitational waves in lower frequency bands 0.1mHz～1Hz. The inter-satellite laser interferometer has a typical structure of a transponder-type heterodyne interferometer, and its essence is an optical phase-locked loop. The simulated inter-satellite laser interferometer is built on the ground, and the frequency of the slave laser is successfully locked to the frequency of the stabilized master laser. The results show that the locking time is more than 2×104s, which meets the detection requirement of low-frequency signals. The interferometer has no coarse errors under different conditions of shorter and longer displacements. The noise caused by environmental disturbances such as temperature and air pressure is the key factor that restricts the accuracy of the interferometer.
