This paper analyzes existing ultrawide-angle objectives (angular field about 180°) for static devices for the orientation of spacecraft toward the sun and with respect to the earth and formulates the requirements on the objectives for such high-accuracy devices. The design features of these objectives are considered. Layouts for four-lens objectives that have been developed are presented and analyzed. © 2010 Optical Society of America. Source

This paper discusses the optical layouts of superwide-angle three-lens IR objectives for static devices for orienting spacecraft with respect to Earth. The optical layouts of wide-angle three-lens IR objectives for a compact thermal viewer are presented and analyzed. © 2013 Optical Society of America. Source

This paper analyzes how the position of the pupils affects the operation of nonmisadjustable optical goniometers equipped with a geometrical-reference channel. These devices are widely used as the sensors of spacecraft-orientation systems. Based on the indicated analysis, the most rational solution is exhibited for preventing noncoincidence of the pupils of the channels from affecting the operation of high-accuracy goniometers with a geometrical- reference channel. © 2012 Optical Society of America.
