This is an enabling technology for the use of small UAV in areas with little connectivity.
High-altitude pseudo-satellites (HAPS) are aircrafts (airplanes, airships or balloons) positioned above 20 Km altitude, ideally designed to fly for a long time in the stratosphere, providing services conventionally served by artificial satellites orbiting the Earth. This activity has to be understood in the context of a renewed interest in HAPS as assets for providing different services, especially telecommunications and remote sensing for civilian or military applications.
Satellite communications industry has been growing rapidly over recent years. There has never been more satellite launches than we have had in the last two years with all the LEO launches. Diversity of satellites, new transmission modes and optimization techniques combined with proprietary standards is all adding complexity to an already challenging environment. As the number of satellites increases, it is expected that the number of interference cases increases as well. This leads to a significant higher amount of effort for satellite operators to identify interference cases.
AI has the potential to be a game changer in the satellite industry, where it could be used to improve processes and increase efficiency. AI could establish a digital assistant, capable of processing information about everyday satellite procedures, resolving and predicting issues before they become errors.

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.
