Abstract: A device for orienting a load about a main axis X and a secondary axis Y is disclosed having a first shaft, called transmission shaft, intended to support the load and configured to be rotated about the main axis and the secondary axis, a second shaft configured to be rotated about the main axis X, a third shaft configured to be rotated about a third axis of rotation, in the same direction as the main axis, a first connection component between the transmission shaft and the second shaft, configured to prevent relative movements between the transmission shaft and the second shaft in, on the one hand, a degree of rotational freedom about the main axis X and, on the other hand, three degrees of translational freedom.

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, 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 and comprising rollers rolling on the central portion of the opposite angle section belonging to the other one amongst said two adjacent segments.
