IFEN to upgrade Galileo open air test bed signals
The German Aerospace Center has contracted with IFEN GmbH for the signal upgrade of the Galileo Test and Development Environment (GATE), per the latest versions of the European Space Agency’s Galileo Signal-in-Space Interface Control Document (ICD) and the GNSS Supervisory Authority Public Galileo Open Service ICD. After completion of the signal upgrade at the end of 2009, the GATE test infrastructure will be capable of transmitting the new CBOC signal structure on the Galileo E1 frequency band and a broader bandwidth of 92.07 MHz on the E5 frequency band, according to IFEN. www.ifen.com |

LMU Computer Scientists involved in Galileo research: Project launched for indoor navigation
The Federal Ministry of Education and Research recently approved the two-year project “Indoor”, which will run until the end of 2010. In this project, Ludwig- Maximilians-Universität (LMU), Munich computer scientists shall be developing positioning and navigation technologies to be used in the field of traffi c logistics and for emergency services. What they are focusing on in particular is indoor positioning and navigation. The aim of the “Indoor” project is to improve certain algorithms that will increase the energy and cost efficiency of locationbased service applications. www.en.unimuenchen. de/about_lmu/index.html

Positive signals for Galileo
The in-orbit validation programme for Galileo, Europe’s global satellite navigation system, is celebrating three years since the fi rst signal was broadcast by the GIOVEA satellite. The programme has been gathering momentum since the launch of the GIOVE-A satellite and its success in securing the critical Galileo frequency filing with the International Telecommunications Union (ITU) before the filing expired in June 2006.Originally designed for a 27 month mission, the satellite has already been operating for more than 3 years.
The launch of the SSTL-built GIOVE-A satellite on 28th December 2005, gave a real boost to the Galileo programme. Just two weeks after launch on 12th January 2006, the satellite transmitted Galileo signals from space for the fi rst time and over the subsequent three months secured the required ITU frequency fi ling. GIOVE-A has enabled Europe to acquire and maintain the Galileo frequency fi ling. Over the last two years GIOVE-A has achieved greater than 99.8% availability and in April 2008 ESA declared GIOVE-A “a full mission success”. In 2008 GIOVE-A was joined by the EADS Astrium-built GIOVE-B satellite – the fi rst to carry an onboard passive hydrogen maser clock, which promises to be the most stable and accurate clock ever fl own in space. SSTL staff assisted ESA with the in-orbit testing of GIOVE-B using the same test facilities as had been developed for GIOVE-A. Recently, a team led by Bremen based OHB-System AG, which includes SSTL as a core team member, has been shortlisted as a possible supplier for the provision of fully operational Galileo satellites to be launched before 2013. www.giove.esa.int |
