Satellites aiding disaster relief
Recent demonstrations have shown how making use of digital processing technology on board satellites can help emergency services share information more effectively during natural disasters.
SkyPlexNet is a project funded by ESA Telecom. The technology that has been developed makes it possible to access satellite resources directly and manage the distribution of the multimedia contents to the remote users independently. It is relatively simple, low-cost and avoids the need to centralise data management at one location.
A demonstration took place in early June 2004. Using a satellite communications network running SkyPlexNet, the Italian Civil Protection Authorities in Piedmont Italy were able to receive and send information via satellite. They were also able to coordinate operations between a central authority and emergency units based all over the country.
They now have connections between 119 regional offices of the Fire Brigade and the headquarters of the Ministry of the Interior (Viminale). It is the first such system in the world which uses On Board Processing. The network also makes use of a new generation of Set-Top boxes wholly developed and produced in Europe.
The operational system is currently located on off-road vehicles. These vehicles act as production and transmission centres. They are equipped with satellite terminals designed to transmit and receive live images to the Fire Brigade Offices and can also provide broadband communications within the areas of operations.
In times of emergency, the vehicles can provide video, data and voice communication, making it possible to video conference with a central authority. The system can also interoperate with the existing terrestrial broadband networks.
According to Alenia Spazio, the Italian company behind the project, "The satellite network for the Italian Fire Brigade opens a new era in emergency and disaster relief in Italy."
Another development includes the Civil Protection Authority in Piedmont which has signed a Cooperation Agreement with the Ministry of Interior to integrate their satellite project Emercom.sat into the SkyPlexNet network. The plan is for the Emercom.sat to become compatible and inter-operable with the Fire Brigade network.
Franceso Rispoli of Alenia Spazio said, "SkyPlexNet allows coverage of the whole of Europe and the Mediterranean basin. It is the first satellite network for emergency applications on a global basis. The next step is to extend this experience to European institutions."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...
Layered 2D material improves efficiency for solar cells and LEDs
In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are creating...
Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
