Sat-Nav Devices Face Big Errors as Solar Activity Rises
By
Old Mr. Sun is getting cranky and churning up its activity which means potential problems for GPS users as they rely on satellite data. Solar flares and radiation may black out the signal and/or give false readings for a period of time.
Researchers say the Sun is awakening after a period of low activity, which does not bode well for a world ever more dependent on satellite navigation.
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.
