Galileo support is required to implement the European Commission’s recently mandated eCall emergency response system for light vehicles, which will automatically send emergency notification messages from these vehicles when involved in an accident. The European Commission’s objective is to have a fully functioning eCall service safeguarding the European Union by late 2015, and CSR’s SiRFstarV is one of the few GNSS receivers that can support the eCall Galileo requirement.
A minimum of four satellites is required to make a position fix in three dimensions – longitude, latitude and altitude. The Galileo constellation’s four satellites are currently visible from Earth at the same time for only two to three hours each day, so currently a position fix can only be obtained during this period. The frequency of position fix availability, however, will increase as the European Space Agency deploys more satellites and as additional ground stations become operational. The full range of Galileo positioning, navigation and timing services is expected to be available in 2018, so automotive suppliers are starting to design in Galileo-compliant solutions like SiRFstarV to support this timeframe.
“This is a major milestone for CSR and the SiRFstarV architecture, validating its capability to support all major satellite constellations including GPS, Glonass, BDS/Compass and Galileo,” says Anthony Murray, Senior Vice President, Business Group at CSR. “We anticipated deployment of the Galileo satellite navigation system and developed the SiRFstarV with this in mind. Our advanced GNSS architecture delivers a feature-rich core platform that not only meets the eCall mandate, but also provides software upgradeability to make full use of the Galileo system as it is deployed over the coming years.”
The SiRFstarV architecture provides real-time positioning based on GPS, Galileo, Glonass and BDS/Compass satellites. For automotive applications, CSR offers SiRFDRive® technology which fuses MEMS and vehicle sensor information along with GNSS measurements to enable continuous and accurate positioning in all environments, including deep urban canyons, tunnels, and parking garages.
