A spacecraft with a chemical and/or electric propulsion system, but without a propellant tank. A more compact design, a reduced mass and easier to demise at the end of life. That is the vision of the team working on the Multifunctional Structure Elements project.
The objective of this project is to develop and manufacture a new generation of miniaturised cameras (M-CAM) based on previous concepts. The "MCAMv3" shall be based as much as possible on “plug and play” features, in order to obtain the smallest generic and qualified space camera owning standard interfaces.
Composite overwrapped pressure vessels used for propellant tanks tend to survive a typical atmospheric re-entry scenario from low earth orbit, thus posing a considerable ground impact risk. Switching to aluminum liners alone is not sufficient since the endlessly wound carbon fibers retain their full strength to above 2000°C and tend to form a perfect insulation layer after pyrolysis of the matrix system.
Digital IF provides analogue to digital conversion (downlink) and digital to analogue Conversion (uplink) of the IF signals in satellite ground stations. This allows signal transport over the standard GbE network and therefore the physical decoupling of the antenna sites from data processing sites.

It aims to solve the problem of key exchange by the use of physics and thus offers the potential of ensuring “unconditional secure” key exchange. Every attempt to eavesdrop on the key-exchange causes errors in the QKD protocol alerting the communicating parties of the attack.
