It's important that GPS users check their systems as soon as possible to ensure that they won't be affected by the impending rollover.' If your GPS falls into either of those categories you need to check with the manufacturer before April 6, otherwise time and position data used for navigation could become inaccurate. Luke Hallett Radio Spectrum Policy Co-ordinator for the Maritime & Coastguard Agency said: 'If your GPS is more than 10 years old or it's had no firmware updates then you're definitely at higher risk of you GPS not working from 6 April. However, if onboard equipment has been installed after August 1999, or has regular firmware updates from the manufacturer, there should be minimal risk of an error occurring. This could cause stand-alone GPS receivers and systems using GPS chips, to produce data that is 19.7 years either in the past or future, therefore generating errors in both the GPS position and time. On April 6 navigation data from some older GPS systems might become inaccurate due to the 'week number' rollover event. Please feel feel free to contact us on should you require any additional information or clarification.The Maritime & Coastguard Agency (MCA) has issued a special safety bulletin to all mariners that use GPS to prepare for a rollover event that will occur on 6 April 2019.

JRC announces measures for GPS week number rollover for equipment that is to occur on some of the GPS' on 4th August 2019. Due to this inaccurate date, the positioning operation may temporarily become unstable or be interrupted.All dated data output by equipment date back to 19.6 years ago.Date displayed dates back to 19.6 years ago (19 December 1999).When GPS week number rollover occurs, our GPS navigator and or sensor may show the following erroneous phenomena: Therefore, when 19.6 years have passed from the reference date in the systems, the clock time incorporated in GPS sensors and navigators will be reset, causing as a result errors in display or output of date or unstable occurrence in positioning operation. The GPS week number rollover occurs every 1,024 weeks which means about once every 19.6 years. This is called “GPS week number rollover”. After week 1,023, the week number count is reset to zero. The GPS system calculates time by counting the number of weeks up to a maximum of 1,023 weeks.
