How was such a clash missed? Because GPS receivers only became common

the peak of their cycle and receivers will likely fail.

The sun is on an 11-year cycle. If 2011 is the date of the max (and we are
apparently in the minimum now), the LAST max was about 2000. Unless the author
believes that GPS receivers only became common after 2000, the user community
has already been through one solar max period.
