The Global Positioning System (GPS) week number will reset to zero on Saturday 6th April 2019.  Many GPS receivers across the world may be affected by this rollover.  Whilst we expect there to be minimal disruption as result of the reset, we are taking steps to ensure our Product Link devices continue to function normally.  We will be updating as many customers as possible by an over the air update.  Where this isn’t possible, we will arrange for an engineer to visit you and make the changes.

The GPS week number rollover occurs every 1,024 weeks and relates to the 10-bit field in a GPS time message.  Due to the counter reset, software in Product Link devices may be affected.

Our teams are on hand to support you during this time and will be contacting any customers who require a site visit. If you have any questions or concerns, please email us at or call 0800 169 2186.
