Limited impact
Hi am working in the GPS devices industry.
The "problem" has been known for decades since the first GPS rollover in 1999.
There are surely going to be issues but it will be mostly for very old legacy equipment.
Also, some devices I work with will be affected, but in 2021. While there is no direct event in 2021, some GPS devices have an internal reference date that they use to know where we are in time. This date is more important than the GPS week rollover date itself, and it shows that problems can happen at any time depending on when the firmware of the GPS device has been designed or built.
In addition, the newer signals broadcasted by the newer GPS satellites have a much longer rollover period, so newer devices will no longer have this problem.
As an engineer and software developped, I am much more worried about 2038. Search for Year_2038_problem on Wikipedia.
I wouldn't want to be in an airplane, elevator, or close to a major industrial plant a few days after and before that time.
Biting the hand that feeds IT
