Thank you for choosing Columbus products and the
long term support.
About the GPS Week Number Rollover (WNRO), GPS uses
a week counter that enables receivers to calculate
the appropriate date. That week counter uses 10 bits
and needs to be reset every 1,024 weeks—roughly
every 20 years. On April 6, 2019—the GPS week
counter will reset to zero.
At this time, the device has a date and time error:
the track date is displayed as Year1999. In
addition, the positioning accuracy of the device is
not affected.
Please note:
1. The Columbus product currently in the market
(using the MTK3339 chip) is unaffected, i.e. devices
with the correct date are not required to update the
firmware.
2. The products involved in this issue are limited
to models sold during the period 2010-2015 and using
the MTK3329 chip.
You can solve the problem simply by updating the
firmware by yourself.
Please select the appropriate firmware update guide
based on your product model: |
