In a sense, this is not really a new discovery. We’ve been told to switch off our notebooks, mobile phones, and in some cases even mobile music players in airplanes because its frequencies can mess with the plane’s navigation system.
However, Tech.co.uk have mentioned in this post that the Swedish Defence Research Agency found that Intel processors seem to have a higher tendency to mess with GPS frequencies. Of course, other processors might not get off scott free either. From the article:
Using a computer in a car, plane, boat, or anywhere a GPS system is used, can mean that the sat-nav device starts working incorrectly. Many modern processors with high clock frequencies – such as those from Intel with frequencies of 1.7GHz, 2.992GHz and 3.2GHz – have been highlighted as possible sources of interference.
“But these are only examples of processors we have chosen to study. I don’t think there would be any difference if we were to pick other types [or processors] since it is the clock frequency of the processor that decides on what frequency the interference occurs,” said Peter Stenumgaard at the Swedish Defence Research Agency.
