On April 6, 2019, a GPS Rollover event occurred.
GPS Rollover events occur every 20 years due to the date and time scale used by the Global Positioning System (GPS), which is based on counting weeks and seconds within a week. When the counter reaches 1024 weeks, it rolls back to week zero. If GPS products are designed without taking this into account, problems can occur with GPS products including incorrect date and time values and/or the loss of position information. Lowrance can confirm that all current generation devices are 100% compatible with the recent GPS week rollover event. There, however, are several legacy products that will require a software update.
