Based on the test data, this paper analyzes the random vibration characteristics of small satellites, focusing on the relationship between the random vibration response and the equipment mass, and proposes an empirical formula for the random vibration response and the panel area density. From the measured vibration data for a satellite during its launch, the ascend-phase vibration characteristics of the satellite is analyzed, and comparisons with the ground test are made. Finally, some suggestions on the ground tests are made.
