The Global Positioning System time epoch is ending and another one is beginning, an event that could affect your devices or any equipment or legacy system that relies on GPS for time and location.
The bug, which some has described as the Y2K of GPS, will cause problems in some GPS receivers such as resetting the time and corrupting location data. The GPS WN rollover event may hurt the reliability of the reported UTC, according to U.S. Department of Homeland Security. HDS said an GPS device that conforms to the latest IS-GPS-200 and provides UTC should not be adversely affected. The agency also provided a word of caution:
“However, tests of some GPS devices revealed that not all manufacturer implementations correctly handle the April 6, 2019 WN rollover. Additionally, some manufacturer implementations interpret the WN parameter relative to a date other than January 5, 1980. These devices should not be affected by the WN rollover on April 6, 2019 but may experience a similar rollover event at a future date”
