Satellite release

If satellites are put into the Earth’s orbit, it is necessary to separate the cone of the rocket from the satellites of the rocket itself. After unlatching the retainer for the nosecones, spring assemblies provide the necessary thrust to put the satellite carriers at the necessary distance. As this movement must be completely linear, the separation manoeuvre is monitored by draw-wire sensors from Micro-Epsilon. Several sensors are attached to the rocket. The tip of the wire is connected to the cone of the rocket. A predetermined breaking point in the wire separates both flying objects from each other when the measuring range has been exhausted. The remaining wire is retracted by the spring effect of the winch drum so that it cannot get entangled anywhere. The sensors based on the WDS-500-MP were specially modified for this application. A spectacular use of Micro-Epsilon sensors in space.
