WebAt midnight April 6, the GPS WN is scheduled to reset, which could be problematic for legacy systems and impact time and the time tags in location data. Utilities and cellular networks also use GPs receivers for timing and controlling certain functions. For instance, the U.S. power grid uses timestamps embedded in GPS. WebThe next WN rollover will occur April 6, 2024. The IS-GPS-200H interface specification identifies both the ten bit WN parameter and the WN rollover events. A GPS device that conforms to the latest IS-GPS-200 and provides UTC should not be adversely affected. However, tests of some GPS devices revealed that not all manufacturer implementations

WebMar 27, 2024 · The legacy GPS navigation message has a ten (10) bit parameter that represents WN. Thus, the WN parameter in the GPS navigation message “rolls over” to zero every 1024 weeks starting from 0000Z January 6, 1980. The next WN rollover will occur April 6, 2024. The IS-GPS-200H interface specification identifies both the ten bit WN … The GPS week number rollover is a phenomenon that happens every 1,024 weeks, which is about 19.6 years. 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. After 1,023, an integer overflow causes the … See more The first rollover took place midnight (UTC) August 21 to 22, 1999.
