摘要: Sun sensors or position sensors may be used to determine the angular location of the sun or other object with respect to the sensor. The sun sensor provides high resolution over a wide field of regard. A position or sun sensor comprises a sensor housing, a plurality of pinholes formed In the sensor housing, a detector mounted within the housing and a method of processing the information detected. The detector is mounted in the sensor housing. Each pinhole has a field of view and the detector receives the images from each field of view. Each field of view is defined by the position of the pinhole relative to the detector. The images are received in an overlay relationship thereby providing a field of regard. The processing method determines the presence and location of an object In a field of regard.

摘要: The present invention provides a method and materials for reducing or limiting charge accumulation and the resulting arc discharges in components used in space vehicles such as satellites prone to charge buildup due to exposure to a charge flux. The material is found in the poly(metallocene) family. In each member of this family, a metal atom is an integral part of the polymer chain, the whole structure being held together (and the interactions provided) by chemical bonds rather than by the proximity of the components in a heterogeneous mechanical mixture. In a homogeneous dielectric, the needed conductivity may be radiation-induced or it may be achieved as the result of doping. The components may be coated with, or alternatively fabricated from, a material including the poly(metallocene) as a constituent.
