DID THE SOLAR STORM CONFUSE THIS LAWN MOWER?
In May 2024, many farmers were dumbfounded when their GPS-guided tractors suddenly went off course. "Our tractors acted like they were demon possessed," reported one observer. The problem was caused by a severe geomagnetic storm.
It might have just happened again--to a lawn mower:
"I have a Lymow One Robotic Lawn Mower," says Carl LeFebvre of Dunedin, Florida. "It uses GPS/RTK to stay on track and is usually accurate down to a centimeter or two. On Nov. 11th, the mower kept wandering off into the garden beds and chewing on flowers instead of its normal diet of turf grass. It didn’t occur to me that it might have been related to the solar storms, until I read the article on Spaceweather.com."
Solar activity poses a growing problem for GPS-guided machines. During big solar storms, the ionosphere fills with bubbles, waves, and turbulence, which distort radio signals from GPS satellites. Severely garbled signals can stop harvestors in their tracks or send lawn mowers into the flower bed.
Readers, if your GPS-guided equipment went off course on Nov. 11-12, let us know.
