Answering the Call for a GNSS Back-up

A government report commissioned by Innovate UK, along with the UK Space Agency and the Royal Institute of Navigation, entitled “Economic impact to the UK of a disruption to GNSS”, comes in the wake of troubling incidents for GNSS operators, both the United States and Europe.

Last year a problem with the GPS satellite timing signal triggered alarms and caused an unknown number of outages, and in Europe earlier this year the fledgling Galileo signal crashed due to unspecified ground facility issues.

Questions in Wake of New Galileo Delay

Some of the specific technical issues behind the latest delay for Galileo’s first full operational capability (FOC) satellites have already been reported. The story, as it is told, generally starts with a late navigation payload delivery by British firm Surrey Satellite Technology to the German prime contractor, OHB. Next, OHB ran into issues with the payload and the platform, further stretching out the timeline.
