Vcdu data recovery system of a satellite

PURPOSE: A VCDU(Virtual Channel Data Unit) data restoration system in a satellite is provided to restore VCDU data by recovering the VCDU data through a network connected to the other base station. CONSTITUTION: A reception unit(310) receives a VCDU data from a base station by connecting to the base station. A synchronization format generation unit(320) generates a synchronization format of the VCDU data. A first transmission and reception unit(330) transmits and receives data by connecting to a data recovery control server(400). When the VCDU data includes faults, a data restoring unit(340) restores the VCDU data by receiving normal VCDU data from the server via the first transmission and reception unit.
