PURPOSE:To simplify the interface between the rocket and the ground by providing a timer loading the rocket controlled from the ground while providing a command receiver operated by instructions from a ground station. CONSTITUTION:A rocket is provided with a timer 6 controlled from the ground and the command receiver 12. A safety switch 2 and a motor switch 3 are turned ON by an operation power supply 12, the power supply is applied to an ignition system 5 by signals from the timer 6, and a first stage of the rocket is ignited. When the safety switch 2, the motor switch 3 and the timer device 6 cannot be stopped for some reason, a drive circuit 13 is actuated through instructions to the command receiver 12 by radio by a command transmitter 14, and each switch 2, 3 and the timer 6 can be stopped. Accordingly, the interface between the rocket and the ground can be simplified, and safety can also be ensured sufficiently. |
