Abstract: A device for deploying and pointing an equipment item is disclosed including a mobile platform for receiving the equipment item, a carrier integrally secured to a wall of a spacecraft, and three identical linear actuators which connect the carrier to the mobile platform and are suitable for moving the platform in translation along one axis and for orienting the platform in rotation about two axes. Each linear actuator including a first portion connected to the platform by a universal joint, a second portion connected to the carrier by a pivot connection, a motor, and a screw/nut joint interconnecting the two portions, each universal joint being suitable for preventing the screw/nut joint from rotating about the axis, such that driving the motor causes a translational movement between the first and the second portion.

Abstract: A radiator for a geostationary satellite is disclosed having a radiative panel perpendicular to a radiation axis, and pivoting relative to the radiation axis, a mounting foot for the panel, a motor which rotates the mounting foot about a rotation axis, the radiation axis and the rotation axis being tilted relative to each other by an angle corresponding to the angle of the satellite's orbital plane relative to the ecliptic plane of the planet, and a guidance system for the panel, limiting rotation of the panel about the rotation axis, including a connecting arm pivoting relative to the satellite about a first axis and relative to the panel about a second axis concurrent with the first axis at a point of intersection of all the axes.

Abstract: A telescopic mast is disclosed including coaxial segments that can be controlled from a stowed position to a deployed position, a set of guide systems disposed between the adjacent segments, a set of systems for synchronising the segments during deployment and a system for driving the segments from the stowed position to the deployed position. Each segment includes the same determined number of angle sections secured together and extending over the entire length of the segment, the number of angle sections being at least three, each segment having a cross-section forming a polygon whose angle sections occupy the vertices of the polygon, each angle having a flat central portion bordered by two side wings, the angle sections of two adjacent segments facing one another. Each guide system is disposed between two adjacent segments being fastened on one of the angle sections of one of the two adjacent segments.
