GPS week number rollover

The Global Positioning System (GPS) broadcasts a date, including a week number counter that is stored in only ten binary digits, whose range is therefore 0–1,023.

Software that is not coded to anticipate the rollover to zero may stop working or could be moved back in time by a multiple of approximately 20 years.

[2] The United States Department of Homeland Security, the International Civil Aviation Organization, and others issued a warning about this event.

[5] Other products that were affected by the rollover include cellphones that were sold in 2013 or earlier,[6] certain types of older Vaisala radiosonde groundstations, suspending launches at some stations for up to two weeks,[7] NOAA's weather buoys,[8] many scientific instruments,[9] and consumer GPS navigation devices.

[12] Honda and Acura cars manufactured between 2004 and 2012 containing GPS navigation systems incorrectly displayed the year 2022 as 2002, with a time offset by several minutes.
