SSTL welcomes a fresh start for Galileo

The agreement calls for more competition to be introduced so that the system can be procured quickly for rapid deployment of Galileo by 2012. This means that more innovative and efficient approaches can be adopted and that a wider range of European small and medium sized companies can contribute to the success of Galileo. This will also bring tangible benefits to the governments and the tax-payers investing in the Galileo system, and ultimately to the end user.

The agreement also calls for the procurement strategy to 'reflect progress made so far'. Under a €28M contract signed in the second half of 2003, SSTL has already supplied the European Space Agency (ESA) with the very first Galileo satellite, GIOVE-A. GIOVE-A's primary mission was to broadcast Galileo signals from space so that Europe could claim the frequencies filed for Galileo with the International Telecommunications Union (ITU). Under the rapidly-paced ESA contract, the satellite was designed, built, tested and launched before the end of 2005 – on-time and on-budget.

Following the signing of the resolution, Group Executive Chairman of SSTL, Sir Martin Sweeting, said: "Through the GIOVE-A projects SSTL has already shown how small and medium sized companies can play a very significant role in Galileo. Over the coming weeks SSTL will be exploring ways of bringing a much-needed fresh approach to the implementation of Galileo".

In January 2006, the first Galileo signals were transmitted from the satellite and in March 2006 ESA was able to confirm that it had brought the Galileo-related frequency filings into use, three months ahead of the official deadline. In 2007 GIOVE-A started to broadcast real navigation messages, containing the information needed by user receivers to calculate their position allowing research centres and receiver manufacturers to extend testing of their Galileo receiving equipment.

A recent announcement by ESA stated that "in the near future GIOVE-A will begin to continuously broadcast the navigation message, with the message content being updated whenever the satellite is visible from the Guildford uplink station. The message content will also be extended to include the time offset between GPS and the experimental Galileo system. Knowing this offset will allow the user to build a position fix using GPS satellites and GIOVE-A." This will also help the research centres and equipment manufacturers to work towards their ultimate goal of user equipment able to work simultaneously with both GPS and Galileo.

Following on from the success of GIOVE-A, in March 2007 ESA placed a contract with SSTL for a second satellite named GIOVE-A2. This additional satellite will help maintain the critical ITU frequency filing secured by its predecessor for a further 27 months, will facilitate further development of ground equipment and may demonstrate additional features of the Galileo System.

Galileo is a joint initiative between ESA and the European Commission. When fully deployed in the early years of the next decade, it will be the first non-military positioning system to offer global coverage.

SSTL develops innovative technologies to change the economics of space, delivering cost effective satellite missions within rapid timescales. The Company is a world leader in the design, manufacture and operation of high performance small satellites with experience gained over more than 25 years and 27 missions launched.

SSTL employs 250 staff working on LEO, GEO and interplanetary missions, turnkey satellite platforms and space-proven satellite subsystems and optical systems. The Company also provides know-how transfer and training programmes and consultancy services, and performs studies for ESA, NASA and commercial customers related to platform design, mission analysis and planning.

Based in Guildford, UK, SSTL is owned by the University of Surrey (85%), SSTL staff (5%), and SpaceX of the USA (10%).

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
