The solar storm knocked out GPS equipment on farms — and it could happen again | 24CA News
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 stated. “They didn’t really have an estimate on how severe or how long lasting the impact would be.”
For Borsa, the issues continued on and off all weekend, in tandem with the highly effective photo voltaic 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 related GPS blackouts and malfunctions on their tools in the course of the weekend.
With extra photo voltaic storms on the horizon and an rising reliance on GPS throughout totally different industries, specialists say the issue is not going away any time quickly.
Why and the way farmers use GPS
GPS, or satellite-based navigation, has change 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 stated. “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 autos even drive themselves, following the traces the GPS mapped out.
“Your seed, your fertilizer, your pesticides, they cost quite a bit of money,” Borsa instructed 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 tools was off by practically two metres throughout Friday night time’s photo voltaic 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 stated.

Craig Frenzen, a farmer in Fullerton, Neb., says rainfall in his area had already stored farmers from seeding throughout their already slim planting window. When the photo voltaic storm knocked out the GPS on one among 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 instructed 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 occur?
The solar goes by means of an 11-year cycle of depth, and is presently in a interval of peak depth often known as “solar maximum” — a phenomenon that is anticipated to proceed by means of the tip of 2025.
During that interval, entangled magnetic discipline traces often known as sunspots can launch sudden explosions of vitality known as photo voltaic flares, which are sometimes adopted by large bursts of charged particles.
“It’s essentially when the sun flings some of [its] material towards Earth,” stated 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 area exploration sector on the Johns Hopkins University Applied Physics Laboratory, walked CBC’s Ben Shingler by means of what’s been occurring on the floor of the solar and the way it might have an effect on our night time sky.
And when magnets meet electronics — just like the satellites in area that GPS depends on — that tends to create “cascading calculation errors,” Arora stated.
Most GPS know-how, Arora says, has a failsafe inbuilt known as knowledge redundancy. That means it is 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 gadgets over the weekend.
Or, Arora says, it might simply 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 stated.
What can we do about it?
Afshin Rezaei-Zare, an affiliate professor {of electrical} engineering and laptop science at Toronto’s York University, research how geomagnetic disturbances impression 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 stated.
“And currently, there is no clear solution for that.”
He’s presently engaged 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 move up what he believes is a first-of-its-kind program at York University.
It will deliver collectively specialists from a variety of fields, from laptop science to astrophysics, with the specific purpose of constructing know-how and infrastructure that’s resilient towards photo voltaic storms and different geomagnetic disturbances.
It’s lengthy overdue, he stated.
“This is [an] urgent need for all of us to … develop something to protect us,” he stated.
CBC has reached out to Canada’s Infrastructure Ministry for remark.
What in regards to 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 customarily has an accuracy of inside a couple of inches. Or they’ll 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 subsequent photo voltaic storm.
But even then, nothing is assured. Borsa says his premium sign by means of Trimble crashed on Friday night, and he ended up utilizing WAAS, then manually adjusting to compensate for its inaccuracy.
If it occurs once more, 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 stated.
