Aerospace Instrument-Making Annotation << Back A way to sun sensors development O.I. Ermakov A new approach to the Sun Sensors development is offered. The approach is concerned with the circular multielement photosensor. As the circular photosensor is applied so an opportunity is appeared to increase accuracy, reliability, survivability, substantially reduce mass and overall dimensions, enlarge field of view. Key words: sun sensor, spacecraft, circular photosensor, resolution, absolute encoder. E-mail: oleg.ermakov@mks.ru. Pp. 3-11.
