As satellite-based navigation plays an ever greater role in US NextGen and its European Single European Sky equivalent to modernise the way in which air traffic is managed, the need to monitor and predict space weather will only increase.

A significant space weather storm occurred when a Wide Area Augmentation System (WAAS) system in the US exceeded its vertical protection limit and was deemed unusable for 15 and 11 hours on two days in October 2003.

Another impact of solar activity occurred in December 2006 when a solar radio burst in a solar flare was so strong that it overwhelmed the GPS signal at L-band, causing a several-minute-long interruption to geodetic-grade GPS receivers operating on the dayside of Earth.

“En route, any decrease in the accuracy the global navigation satellite signal is not such an important issue, say, if you are 10 metres out but it starts to get tricky if you are using it for precision approaches,” says the UK CAA’s Wells.
