Successful completion of AmerHis, the first switchboard in space

23.11.2006
On 22 November 2006 in Madrid, the European Space Agency, the Spanish Centre for Industrial Technology Development (Centro para el Desarrollo Tecnológico Industrial – CDTI) and Hispasat, a Spanish telecommunications satellite operator, signed an agreement marking the successful completion of the AmerHis system implementation.

The document was signed by Giuseppe Viriglio, ESA’s Director of Telecommunications and Navigation Programmes, Maurici Lucena, Director General of CDTI, and Petra Mateos, President of Hispasat.

AmerHis is an advanced communications system which works as if it was a switchboard in space: it is based around an on-board processor carried by Hispasat’s Amazonas satellite. This processor has the capacity to decode incoming signals from the satellite’s four transponders, switch data streams between transponders, and encode them for retransmission. Each transponder covers one of the four geographical regions served by the satellite, namely: Europe, Brazil, and North and South America.

Thanks to AmerHis, Hispasat is able to offer broadband interconnectivity to users anywhere within the four geographical areas covered by Amazonas, with highly efficient usage of the communications capacity. It also allows Hispasat to differentiate its portfolio of services from those of its competitors and to position itself as one of the most advanced satellite operators on either side of the Atlantic.

Under the terms of an agreement made between ESA, CDTI and Hispasat S.A., ESA funded and managed a contract for the implementation of the on-board processor and its complementary terrestrial infrastructure and terminals – collectively known as the ‘AmerHis System’. The main funding for AmerHis was provided from the Spanish contribution to ESA’s ARTES Programme, with additional support from France, Norway and Canada.

CDTI has implemented activities in support of AmerHis in the context of the Spanish National Space Programme. They will continue to support evolutions of and improvements to the system during its operational life.

The industrial consortium was led by Alcatel Espacio (Spain), who were also responsible for development of the on-board processor. The Amazonas satellite was launched on 5 August 2004 and the payload has been successfully subjected to extensive in-orbit testing.

The AmerHis ground segment, comprising the Network Control Centre (NCC), the satellite gateways and the user terminals, has been operational since April 2005. Final acceptance of the ground segment took place on 14 July 2006 and it has been operated by Hispasat since that date. A new era is starting for AmerHis – its commercial life with the first Spanish operator.

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
