High Altitude Pseudo Satellites (HAPS) are stratospheric platforms that stay over a fixed point on Earth from weeks to months. Capitalising on these developments, the European Space Agency is reaching out to the Telecommunication, Earth...

This is a unique opportunity to gain an overview of all the recently completed activities and to discuss them with colleagues from both ESA and industry across the satellite telecommunications sector.
In Electric Propulsion systems often cross-switching of high voltage lines is required.
Nowadays this kind of switching is usually done with high voltage relays. Benefits are expected by replacing the relays with semiconductors.
The challenge will be the use of advanced semiconductors capable to deal with high voltages, related to Hall Effect Thruster and Ion Engines.
Satellite services in the High North are utilised extensively for both communication purposes and for earth and climate observations. The project results are based on up to three year measurements at 20 GHz with co-sited meteorological data. They suggest that services can be provided with 99 % availability for systems with elevation angles as low as 3.2.
