Has anyone already discussed the problem with the GPS System date rollover that will occur Saturday April 6, 2019?
The problem arises because when GPS was invented in 1980, the date and time was represented by a counter that could only count forward a maximum of 1024 weeks, or about 19.7 years.
After 1024 weeks, this counter ‘rolls over’ to zero and this can potentially cause a satnav or other system to shut down.
The first rollover occurred in August 1999 - when comparatively few GPS devices were in operation.
But the second rollover will occur at 1am GMT on April 6, 2019.
