ABSTRACT:
A guidance system for of vehicle, such as a model airplane which has directional control devices. A device is mounted on the vehicle or at some remote station to generate a command attitude signal. At least two sensors are mounted on the body of the vehicle and face in opposite directions away from the body of the vehicle. These sensors are connected together in such a way that radiation falling on the sensors causes the sensors to produce a signal such that the signal at the junction between the sensor is functionally related to the orientation of the vehicle. A servo mechanism is mounted on the body of the vehicle and is connected to the directional control devices of the vehicle. An electric circuit is connected between the signal from the sensors and the device that generates a command attitude signal and the servo mechanism. In this way if the vehicle changes its attitude, the sensors send a signal to the electric circuit which causes the servo mechanism to correct the attitude of the vehicle, so that the vehicle is maintained at the command attitude.
