Interesting paper from 2018 quantifying the impact of on systems.

The 🇨🇳 BeiDou system was outperforming 🇪🇺 Galileo and 🇺🇸GPS during solar flare conditions due to more frequently updated broadcast ionospheric models.

I know Galileo/EGNOS did a recent system upgrade to provide increased resilience against solar peak activity, anticipating Solar Cycle 25, but not sure what those consisted of. Maybe @bert_hubert would know?

"the solar storm ruined the accuracy of RTK systems for many farmers using John Deere tractors”

"Tom Schwarz, who owns an organic farm in Nebraska, told me he had to stop planting on Friday and Saturday because of the issue, and said that the outage, combined with a bad weather forecast in the next few days, is threatening the small time window that he has to plant corn.”

According to the Deere website, their Radio RTK does only use GPS and GLONASS.
