GNSS (Global Navigation Satellite Systems) is a common acronym encompassing all existing and planned satellite-based navigation systems. So far, the US-built GPS dominates the scene completely, but the Russian GLONASS is approaching around-the-clock global operational status, and other systems are being developed (the European Galileo, the Chinese Compass/Beidou and the Indian IRNSS). There are also augmentation…
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
