Tanner Borsa was working his farm close to Yellow Creek, Sask., final weekend when the Global Positioning System in his tractors stopped working.
Like many farmers, Borsa pays for a premium GPS satellite tv for pc sign to make sure accuracy and effectivity when he is planting seeds and spraying pesticide and fertilizer. When that sign went out on Friday night time, he known as his supplier.
“They basically told me that it’s a solar flare [and] there’s nothing they can do about it,” Borsa mentioned. “They didn’t really have an estimate on how severe or how long lasting the impact would be.”
For Borsa, the issues continued off and on all weekend, in tandem with the highly effective solar storms that introduced dramatic views of the northern lights to a lot of Canada and the U.S.
He’s not alone. Farmers throughout Canada and in some elements of the U.S. skilled comparable GPS blackouts and malfunctions on their equipment through the weekend.
With extra solar storms on the horizon and an growing reliance on GPS throughout totally different industries, consultants say the issue is not going away any time quickly.
Why and how farmers use GPS
GPS, or satellite-based navigation, has turn into normal within the agricultural sector.
Jordan Wallace, a farmer who runs the GPS retailer and distributor GPS Ontario out of North Gower, Ont., says he was fielding dozens of calls all final weekend from farmers from B.C. to P.E.I., in addition to prospects in Texas and Georgia.
“In agriculture right now, we’re at the height of the planting season,” he mentioned. “And accuracy of signal is of extreme importance.”
Farmers use GPS on their tractors, sprayers and harvesters to make sure they evenly distribute seeds, pesticides and fertilizer with out overlap. Some automobiles even drive themselves, following the traces the GPS mapped out.
“Your seed, your fertilizer, your pesticides, they cost quite a bit of money,” Borsa advised CBC from his self-driving tractor. “And over-applying them or overlapping as you work your field is basically wasting money.”
Luke McCreary, a farmer close to Bladworth, Sask., says his GPS equipment was off by practically two metres throughout Friday night time’s solar storms, forcing him to manually compensate.
“Anywhere that I’m driving manually instead of using the GPS, we’re missing out on the optimization … that we hope to get when we have systems like this installed on the tractor,” he mentioned.

Craig Frenzen, a farmer in Fullerton, Neb., says rainfall in his area had already saved farmers from seeding throughout their already slim planting window. When the solar storm knocked out the GPS on one in every of his tractors, it put him even additional behind.
“When we do get the right conditions to plant, we have to go, and GPS helps us do that,” Frenzen advised As It Happens host Nil Kölsal.
“When that is not available, and we don’t have the mechanical markers on our planters anymore, you’re done, you’re stopped, you’re dead in the water.”
Why does this happen?
The solar goes via an 11-year cycle of depth, and is at the moment in a interval of peak depth referred to as “solar maximum” — a phenomenon that is anticipated to proceed via the top of 2025.
During that interval, entangled magnetic subject traces referred to as sunspots can launch sudden explosions of vitality known as solar flares, which are sometimes adopted by large bursts of charged particles.
“It’s essentially when the sun flings some of [its] material towards Earth,” mentioned Nikhil Arora, an astrophysicist and postdoctoral researcher at Queen’s University in Kingston, Ont.
“Think of, like, protons or electrons that are coming towards us. Now, these protons and electrons also carry a magnetic field. Like, they’re essentially just very tiny magnets.”
Ian Cohen, an area physicist and deputy chief scientist of the house exploration sector on the Johns Hopkins University Applied Physics Laboratory, walked CBC’s Ben Shingler via what’s been occurring on the floor of the solar and how it could have an effect on our night time sky.
And when magnets meet electronics — just like the satellites in house that GPS depends on — that tends to create “cascading calculation errors,” Arora mentioned.
Most GPS know-how, Arora says, has a failsafe inbuilt known as knowledge redundancy. That means it’s consistently storing copies of its measurements, and within the case of a glitch, makes use of that saved reminiscence to regulate accordingly.
That could clarify why most individuals did not discover any impacts on their telephones, vehicles or different GPS-enabled units over the weekend.
Or, Arora says, it may have been the luck of the draw.
“Not all satellites at every time will see the solar flare or the sun storm. It might just be these particular satellites that were in the path of the solar storm,” he mentioned.
What can we do about it?
Afshin Rezaei-Zare, an affiliate professor {of electrical} engineering and pc science at Toronto’s York University, research how geomagnetic disturbances influence know-how. He says GPS is “highly vulnerable” — particularly in Canada, as a consequence of our excessive latitude.
“We are relying more and more on advanced technologies, which are highly vulnerable to solar storms, and so we’ll have these effects more and more in the near future,” Rezaei-Zare mentioned.
“And currently, there is no clear solution for that.”
He’s at the moment working on altering that.
Thanks to a $1.65-million federal grant from the Natural Sciences and Engineering Research Council of Canada, Rezaei-Zare is about to go up what he believes is a first-of-its-kind program at York University.
It will deliver collectively consultants from a variety of fields, from pc science to astrophysics, with the specific aim of constructing know-how and infrastructure that’s resilient towards solar storms and different geomagnetic disturbances.
It’s lengthy overdue, he mentioned.
“This is [an] urgent need for all of us to … develop something to protect us,” he mentioned.
CBC has reached out to Canada’s Infrastructure Ministry for remark.
What concerning the subsequent time?
Farmers in North America have two choices for tapping into GPS alerts, says Wallace. They can use the free sign, known as Wide Area Augmentation System (WAAS), which depends on cell towers and typically has an accuracy of inside a couple of inches. Or they will shell out $100,000 to $200,000 yearly to entry premium alerts that faucet instantly into satellites, and is normally correct inside a pair centimetres.
Over the weekend, he says he was switching prospects to these premium alerts, which he says are typically extra steady.
Trimble, a GPS supplier that Wallace’s firm sells, is urging its prospects to improve alerts and GPS receivers to be higher ready for the following solar storm.
But even then, nothing is assured. Borsa says his premium sign via Trimble crashed on Friday night, and he ended up utilizing WAAS, then manually adjusting to compensate for its inaccuracy.
If it occurs again, he’ll do the identical.
“It’s definitely a concern, but I don’t really know if anything can be done about it. You just kind of got to make do with the hand you’re dealt,” he mentioned.
