Scoop: Solar storm is causing farmers' tractor GPS systems to go haywire. Many have shut down planting altogether during a critical period. A Deere dealer said accuracy is "extremely compromised"

Solar Storm Knocks Out Farmers' Tractor GPS Systems During Peak Planting Season

The accuracy of some critical GPS navigation systems used in modern farming have been "extremely compromised," a John Deere dealership told customers Saturday.

This is a reminder of how much modern tractors rely on satellite and internet connections. Many farmers can't or won't plant right now bc tractors have been highly automated to increase yield. Rows are planted so tightly together that humans can't navigate them w/o killing crops

One farmer called it a "shitshow." Another: "All the tractors are sitting at the ends of the field right now shut down because of the solar storm." Another said their systems that are normally centimeter-accurate were off by 3-6 feet and tractor kept "wandering off" and had to be constantly corrected.

This, from a John Deere dealer, is wild. They warn that affected tractors operated during this time will likely have made maps that are wrong, which will be wrong throughout the growing system, and which are wrong in an inconsistent way

@jasonkoebler Interesting to figure out who or what fucked up here. SBAS/WAAS provider? DGPS makers messing up ionospheric correction? Space weather parameters out of spec for the software running on the RTKs? All of the above?

nb: As much as I dislike Deere, this should be handled completely blameless, the way the FAA handles an investigation. So many lessons to learn here.

@thetaphi @jasonkoebler kinda hard to run accurate GPS in the middle of a G5 class geomagnetic event tbf.

@gsuberland @thetaphi @jasonkoebler Indeed, which also suggests that the over reliance on GPS for centimeter accuracy in crop planting is a nasty failure mode that should be avoided.

The solar storm is just a dress rehearsal 🎭 for nation state actors knocking out GPS and causing food shortages.

@matthewskelton @gsuberland @thetaphi @jasonkoebler do you think that's the most important thing for farmers to prepare for?
