VxWorks keeps gps up and running
According to Wind River, VxWorks has been chosen to run Logica's Integrity Processing Facility (IPF) check set for the European Geostationary Navigation Overlay Service (EGNOS).
The IPF validates information broadcast by the satellites to safety critical users, such as aircraft in flight or ships navigating through narrow channels.
Consisting of three geostationary satellites and a network of ground stations, EGNOS augments the US GPS and the Russian Glonass systems, making them more suitable for safety critical applications. It allows users to determine their position within 2m, compared with about 20m for GPS and Glonass.
EGNOS IPF has completed safety certification to EUROCAE ED-12B Level B (directly equivalent to RTCA DO-178B Level B) running on Intel architecture, which was an important milestone in enabling EGNOS to be used for safety critical applications.
