Notice on GPS Week Number Rollover - 6 April 2019

The GNSS receivers manufactured by Tersus GNSS Inc. can be used normally when the GPS week number rollover occurs. They are not affected by this event and do not need to be upgraded.

What is Happening

On 6 April 2019 there will be a Global Positioning System (GPS) week number (WN) rollover on Coordinated Universal Time derived from GPS receivers and devices. 

The GPS system stores the current week number as a 10-bit number. Therefore, every 1024 weeks, the week number rolls over to zero. The start date for the week number count was 6th January 1980. The next rollover event is due on 6th April 2019.
