The invention discloses a satellite shell for protecting spacecraft time reference equipment and a protection assembly, which belong to the field of universe navigation equipment. The device comprisesa satellite shell plate body, a mounting outer box,and a connecting assembly, wherein the mounting outer box is fixedly arranged on the satellite shell plate body; a cavity is formed in the mountingouter box; a vibration reduction platform is arranged in the inner cavity; the vibration reduction platform is used for mounting a crystal oscillator; the connecting assembly is used for connecting the satellite shell plate bodies which are adjacently arranged. The satellite shell plate body is used for protecting a component provided with the crystal oscillator; the influence of external impact on the crystal oscillator is effectively avoided, and stable execution of the performance of the spacecraft is ensured; and a double-layer protection structure is designed, the supporting strength of key parts is guaranteed, low-frequency vibration reduction and impact resistance can be achieved, the advantages of being light in weight and high in rigidity are achieved, power consumption is reducedand the short-term frequency stability index of a product is improved on the basis that the performance index of the protected product is not affected, and high practical value is achieved.
