The provision of a ground station and associated satellite capacity will enable the German Federal Agency for Technical Relief (Technisches Hilfswerk – THW) to connect their mobile command post in Heiligendamm to their headquarters in Bonn.
Telephone and data connectivity will be provided by a mobile satellite communications system whose core elements have been developed under an ESA ARTES 3 (Advanced Research in Telecommunications Systems – Multimedia Programme) project by ND SatCom GmbH and which is built upon their SkyWAN product. SkyWAN is a satellite terminal system using small antennas, which can establish a wide-area network infrastructure for mobile or transportable applications.
The innovative concept from ND SatCom which is demonstrated with this project enables agencies like first responders, fire fighters, or crisis managers to immediately use the services of a shared ‘always-on’ satellite network whenever they require, thus optimising satellite capacity expenditures and service availability.
Shared crisis and contribution network
With support from ESA, ND SatCom – a supplier of satellite-based telecommunication solutions located in Friedrichshafen (Germany) – has designed a shared satellite system capable of immediate broadband communication in case of emergencies and otherwise able to be used for information gathering.
For the THW command post at Heiligendamm, connectivity is being provided via the HellasSat2 satellite, which has been chosen as it is part of ESA Telecom's technical assets.
The system deployed for the G8 summit has been tailored to the needs of THW and is using about 3 MHz of bandwidth on the satellite. The bandwidth is shared between two communication channels with information rates of about 2 Mbps and 0.8 Mbps.
As part of the project, ND SatCom has also implemented a lightweight, car-top transportable antenna and associated control and pointing software, called SkyRAY light.
For major events such as the G8 summit, where additional and reliable telecommunication facilities are required, it is no longer necessary to set up complex and expensive conventional infrastructure for one-time utilisation. The use of a satellite-based network does away with the need to connect to traditional terrestrial telecommunications infrastructure or radio link systems.
Command centres and mobile units are equipped with compact mobile and fixed satellite terminals which support telephony and data exchange independent of other networks.
This first application of ND SatCom’s network at the G8 Summit is based on a co-operative undertaking by ESA, ND SatCom, THW, the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt – DLR), and the supplier of fire-fighting and rescue technologies GIMAEX-Schmitz.

Researchers create new technique for manipulating polarization of terahertz radiation
20.07.2017 | Brown University
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
