Announcement: GPS Week Rollover on 6 April 2019
Just to inform you, there is an expected issue with the global GPS system<https://base.xsens.com/hc/en-us/articles/360019813434-Does-the-GPS-week-roll-over-April-6-2019-affect-Xsens-MTi-sensor-modules-with-GPS-> that will occur on April 6, 2019.
Basically, the system communicates time as the number of weeks since January 6, 1980. But it stores it in a number that can only go to 1023. So every 20 or so years the number reaches 1023 and must reset to zero. If a GPS receiver is not ready for this, it can get confused and the calculated time will be incorrect.
The good news is that the u-Blox GPS receivers that Xsens uses (G-710, MTi-7 support) will not be affected.
