摘要
A method and apparatus for defining an equipotential plane in the static electric field existing in the earth's atmosphere, the invention utilizes the static electric field as a reference for generating an information-bearing electrical signal. Electrostatic sensing probes placed on a blade or rod member rotating in a plane either effectively parallel to or perpendicular to a given axis of an airborne vehicle allows detection of the attitude of said axis relative to an equipotential plane existing in the atmosphere, which equipotential plane may be typically used as a reference to stabilize the airborne vehicle relative to the earth's surface. The plane in which the sensing probes rotate is referenced to the horizontal equipotential planes existing in a gradient fashion in the atmosphere, rotation of the probes in a plane parallel to the earth's surface (thus usually parallel to the aforesaid equipotential planes) producing a zero output from a differential voltmeter or ammeter connected to the probes. If the plane in which the probes are rotating pitches downwardly, upwardly, or banks, a signal is produced having an amplitude proportional to the angular attitude of the said plane relative to a reference plane, e.g., an equipotential plane in the atmosphere, and a phase related to the azimuthal direction of maximum tilt thereof. The signal thus generated can be used to alter the orientation of the plane in which the probes are rotating to produce a desired stabilization of an airborne vehicle.
