Abstract: A device for controlling the attitude of a satellite exploiting solar pressure, includes at least two solar generators destined to be arranged on either side of a central body of the satellite and each having one face to be exposed to the Sun, referred to as “front face”, the device also including at least three surfaces whose optical properties can be commanded. The surfaces whose optical properties can be commanded are arranged on flaps connected to solar generators, each flap being fixed with respect to the solar generator to which it is connected, and such that, in the operating position, at least two of the surfaces are not parallel when the front faces of the solar generators are optimally oriented with respect to the Sun. The device further includes a module for commanding the optical properties of each surface whose optical properties can be commanded.

Abstract: An optical fiber ribbon cable in which the edge fibers are protected from experience excessive stress from impact of the like during manufacturing, installation and use. The cable includes an optical fiber ribbon having a plurality of optical fibers arranged in parallel including edge fibers respectively located on opposite edges of the ribbon and interior fibers located between the edge fibers; and an optical fiber jacket surrounding the ribbon and defining a first space between said jacket and each of the edge fibers and a second space, contiguous with said first space, between said jacket and the interior fibers. The width of said first space adjacent the edge fibers is greater than a width of said second space adjacent the interior fibers.
