There is zero evidence of elevated cosmic ray- induced cosmogenesis observed for 'ANY' magnetic excursion, or reversal over the past 150-million years.
Lack of increased cosmogenesis indicates no loss or decrease of the magnetic field flux.

Observation is complete opposite of what you assume.
As the poles have moved over the last 160 years it's gotten weaker, its moved more in the last 20 years than the previous 120 years and also weakened more in the last 20 years than the past 120.
So what makes you think as the poles move the magnetic field won't lose strength?
The gps satellites are up about 12,000 miles, they could quite easily be outside of the earth's protective field while the atmosphere is still quite well protected.
Can you assume that things 12,000 miles up will be protected?
