Satellite ground stations combine the requirements of 7/7 uninterrupted operation, many years of field service and the implementation of computers in some odd places on the globe. Kontron VME Integrated Platforms have been selected to be the heart of the future European GPS system ground stations. The eleven 6U VME x86 board Platform processes the ultra precise clock signals which give this positioning system its outstanding precision. Turn-key computers have been delivered to multiple partners of the program. They operate under Linux or a certifiable version of a Real-Time O.S.
