PURPOSE:To enable accurate calibration of a time signal in an extremely remote equipment such as satellite by executing time signal calibration command at an assigned time of the earth. CONSTITUTION:Equipment to be calibrated arranged at a remote point has a time signal generator section 2 containing a time signal presetting shift register 21 and a command decoder section 1 for providing a specified time signal preset command at an assigned time connected thereto 21 It also has a telemetry means 3 for informing a sender of the time signal calibration command. The calibration commands for time signals are executed only when coincidence with time signals attached as apart of the commands is detected. This enables the sending of time commands as desired thereby assuring accurate calibration of time signals in remote equipment to be calibrated. |
