A stacking device for a space vehicle comprises a plurality of hold down and release mechanisms and is configured to hold, temporarily, n space appendages, n being an integer strictly greater than 2, on one and the same support of a space vehicle using hold down and release mechanisms. The stacking device is arranged such that several space appendages are held by one and the same hold down and release mechanism. An associated space vehicle comprising at least one such stacking device is also provided.

A control device for a linear actuator comprises a motor coupled to a device for converting a rotational movement into a translational movement configured to move a translationally mobile part. The actuator comprises at least one mechanical stop placed on a fixed part of the actuator, the group of at least one mechanical stop being configured to act as an obstacle to the relative helicoidal movement of a stud of the translationally mobile part when the stud reaches at least one predetermined position, contact of the stud with a stop generating a torque. The control device comprises a control module connected to at least one strain gauge configured to generate a signal indicative of the detected torque, the control module being configured to compare the amplitude of the signal generated by the group of at least one strain gauge against at least one predetermined value.

An active tie rod for retaining and releasing appendages without shock is provided. The device comprises: a fixed base, a tie rod extending along an axis between two ends, a mechanism fastened to the base and temporarily retaining a first end of the tie rod, operating the mechanism to release the tie rod from the base, an end piece fastened to a second end of the tie rod, at least one appendage temporarily retained between the base and the end piece, a component disposed between the mechanism and the end piece, and an actuator of the component to modify a characteristic dimension of the component along the axis between two values, the component producing a tension in the tie rod for the first of the two values and the tension in the tie rod being reduced for a second of the two values.
