This is exactly the sort of thing that leads to people getting reincarcerated after their electronic monitoring devices mistakenly report them leaving their homes.

Some reporting I did on the topic a few years back: https://chicagoreader.com/news/many-on-house-arrest-in-cook-...

TFA article claims: "Indeed, the solar storm of May 2024 is estimated to have cost the US agricultural industry $500 million due to disruptions in precision navigation."

This seems hard to believe. The link provided hand waves through how it maybe could happen, and ends with an Economist just SWAGing that it could have been maybe a dollar an acre or so.

"He estimates that affected farms lost about $1 per acre. Nationally, this equates to an estimated half-billion dollars in lost earning potential, Griffin says."

So yeah, hard to believe was the right call. Very few farms were affected, but if we assume half of the total 900 million acres of farm land were, add 10% to get a round number, and guess it at a dollar per acre, we get the quoted big number.

It seems worth mentioning that the last time GPS had issues like this afaik, it was due to the US utilizing 'selective availability' due to national security issues. We used it somewhat famously during the 9/11 attacks.

Also the page 404's via archive.org, but information formerly from gps.gov can still be found here: https://archive.ph/trwOo

Edit: The selective availability page moved to https://www.gps.gov/selective-availability

An interesting warning as Austin is blanketed by Cybercabs. I think a town full of golden driverless cars 33 feet from where they think they should be is terrifying.

Wouldn't RTK help mitigate this, as the base stations would also be affected by the atmospheric disturbance?

Somehow, Selective Availability returned.

The gps on my phone drifts by a few city blocks all the time...

were other satellite positioning systems affected as well? was it checked that it wasn't just a misconfig on US command side?

TL;DR:

1. Not today. November 2025. They don't make it clear.

1.1. One would expect that to be put in the title, when the article is written almost a year after that.

1.2. No, the article doesn't state that in the first paragraph. Posting in it full seem to be the only way to fend off lazy comments:

  In November 2025, Earth was buffeted by several massive eruptions of solar material that slammed into the magnetosphere.
That's it - the whole paragraph. Several paragraphs later - GPS first mentioned. No clear links between dates stated.

2. It is unclear what is the source of the claim.

UPD: Commenter below found the source, but TFA doesn't make a good job of presenting that as a source of the 33 feet glitch claim, but rather posts another citation from it.

They should've just quote this and be done with it:

  During the storm main phase, an east–west elongated band of intense auroral brightness expanded equatorward, producing a horizontally extended strip of strong density gradients that favored the development of small-scale irregularities. These small-scale irregularities triggered pronounced amplitude scintillations (S4 > 0.5) and caused significant positioning errors exceeding 10 m—large enough to disrupt GNSS-dependent applications across CONUS for hours, particularly precision agriculture and autonomous transportation industries. [1]
3. Navigation issues happened before, they state it right there. They were more disruptive as well.

4. The author has articles all over the topics. Everything is sensationalized.

5. Every presented link seem to have this awful Cloudflare js challenge.

Bad article overall.

P.S. Response to the false claim below - no, there's nothing about GPS in "the first 3 words of the article".

not just space weather, I am pretty sure the atmosphere is being disturbed by toxic human activity both by accident and on purpose

I've run outside every morning for decades and used Garmin with GPS since 2015, I've never had so much trouble

Garmins finally supports dual-band (L1+L5) and BeiDou on newest models but it's still not enough to compensate, I have to use a Stryd footpod to guarantee accurate distances/speed

btw BeiDou GPS blows away US GPS for number of sats and precision but despite Russia's GPS being legal in US, technically BeiDou is not
