This paper proposes a new approach to provide RF communication channel and electric power transmission to overcome the weakness of conventional tests, which may cause several problems. When an RF communication device is used to communicate between launch vehicle and launch complex in stead of using harness umbilical, it may draw the simplicity of ground test equipments, cost-saving, and the reduction of test time. In addition, if an RF power transmission device is adopted to supply on-board power of launch vehicle, it can replace expensive on-board batteries, which may be degraded easily by the repeated charging and discharging processes.
