Sat-nav devices face big errors as solar activity rises

The BBC has an interesting post on the potential disruption to satallite navigation due to increases in solar activity (sun flares). Now that we live in a global infrastructure that is vulnerable to communication 'impacts', such issues are worth considering:

The Sun's irregular activity can wreak havoc with the weak sat-nav signals we use.
The last time the Sun reached a peak in activity, satellite navigation was barely a consumer product. But the Sun is on its way to another solar maximum, which could generate large and unpredictable sat-nav errors.It is not just car sat-nav devices that make use of the satellite signals; accurate and dependable sat-nav signals have, since the last solar maximum, quietly become a necessity for modern infrastructure...

...So as the Sun builds up to its peak in a few years' time, be aware that your sat-nav may for a time give some strange results - or for a short while none at all.
