Too high frequency. GPS relies on direct line of sight, and not bouncing signals off the magnetosphere. (This is generally true of all satellite communications)

- mlyle 4y agoThe ionosphere does weird things to GPS signals as it gets charged up. Delays change based on angle of incidence. A key part of receiver accuracy is the ionosphere model. If you ignore ionospheric effects your position is likely to only be accurate within about a kilometer.
- Rebelgecko 4y agoIIRC these types of solar events can cause some turmoil and even change the size/shape of the atmosphere. That can change how long it takes the GPS signals to get to your phone, which can add noise to the trilateration calculations. Fancier receivers have some clever ways to mitigate that, but your average cell phone GPS chip may lose some accuracy.
