Ignore it - it's not going to effect GPS.
Other satellites — like GPS satellites, which use a medium Earth orbit (an altitude of about 20,000 kilometres) and don't orbit the equator, are also at risk of interference from the sun, because all satellites pass between the Sun and the Earth at some point.
But it won't necessarily be around the equinox.
Because of the different planes of orbit they inhabit, they won't be disrupted at the same time as geostationary satellites.
And because their orbit is faster, any outage is briefer.
Dr Aboutanios said non-geostationary satellites also typically have stronger signals, making them more resilient against the Sun's interference.
And next time you see a story about high K-index possibly causing trouble, ignore that too
These sky-is-falling stories come out all the time but there's never been any noticeable impact on drone flying.
At worst it may make your GPS position data a metre or two off.
But since GPS already has a 1-2 metre inaccuracy you wouldn't notice it if it did.
