The 3D thermal IF is a 3D heat pipe using ALM techniques, hydraulically connected to a standard AGHP132, in order to significantly reduce thermal gradients from the equipment unit to the radiator panel. It is characterized as in “3D” since it is interfacing equipment’s face, and not its baseplate.This entails the need to operate in gravity conditions.

Over the past two decades, Airbus Defence and Space Netherlands (Airbus DS NL) has developed, and continuously updated, a non-explosive low shock hold down and release system for its Advanced Rigid Array and Flatpack solar array families. Many hundreds of these systems have released in orbit - with 100 percent success rate - on a variety of solar arrays and other deployable systems.

The objective of the NELS program is to qualify the successor of the existing hold down and release system, which is more robust and has an extended preload capacity.

In this ARTES C&G phase, Airbus DS NL has qualified the NELS design. At the end of the qualification test campaign the NELS product is considered flight qualified and ready for first application programme implementation.

Traditional TT&C links still utilize frequency division as access method together with bandwidth inefficient modulations. The use of direct sequence spread spectrum (DSSS) modulation opens possibilities for more secure links with improved interference immunity. For
satellites utilizing electric orbit raising, the use of DSSS is particularly useful since it eliminates the need for detailed frequency scheduling when passing below the GEO belt over a prolonged time frame.

To address the challenges with thermal control in space, Airbus Defence and Space Netherlands (Airbus DS NL) has developed the HiPeR product range:
     - HiPeR Flexlinks: these are thermal straps with unprecedented capability to conduct heat on-board spacecraft. Highly flexible and with a conductance-to-mass ratio (W/K per kg) three to five times higher than traditional solutions, the thermal straps offer a versatile solution for thermal control requirements, while being mechanically decoupled (visit our webpage here).  
     - HiPeR Radiators: provide high design flexibility through their low mass and low stiffness performance. They can be used to complement or replace traditional radiators.  In doing so, they enable optimized designs along mechanical and thermal properties without infringing one or the other.

5G-GOA develops and implements the necessary modifications in the 5G New Radio standard to enable the direct radio access of terrestrial communication networks via satellite, a 5G RAN via satellite closely following the 3GPP Work Item on Non-Terrestrial-Networks. The hardware and software development relies on and uses existing technologies, hardware and software components already available from the open source project OpenAirInterface™ for the prototyping of 5G terrestrial systems. Our solution is directly based on 3GPP discussions and results and covers physical layer techniques (e.g. synchronisation) up to specific protocols and upper layer implementations (e.g. timers and random access procedure) of the radio access network, as needed. 5G-GOA focuses on geostationary satellite systems.

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.
