2019 GPS Week Rollover
2019 GPS Week Rollover

The 2019 GPS Week Rollover would have a potential effect upon GPS receivers (including GPS sensors and GPS receivers embedded within MFDs, chartplotting products, AIS receivers, and VHF radios). Any features which are dependent upon date/time information (tide / current data, waypoint/route creation date, Time, Date, slow / no acquisition of GPS FIX, etc.) would potentially be affected by this feature. This feature is rooted in the make/model of GPS receiver which has either been constructed into the product or that the product has been interfaced and the GPS chipset used in it's manufacture. Accordingly, should one determine that the date/time information reported by the system is incorrect following the 2019 GPS Week Rollover event (April 6, 2019), then it may be necessary to either replace the system's GPS sensor, add an external GPS sensor to the system, or replace the GPS sensing device (should no software/firmware update be available to address the 2019 GPS Week Rollover event).

Raymarine is presently investigating this issue and will release updated information at a later date. At that time, this FAQ will be updated with the latest information on this subject. As of the date of this response, we are confident that each of the following products are unaffected:
- Axiom / Axiom Pro / Axiom XL MFDs
- a/c/e/eS-Series MFDs
- Raystar 130/150 GPS Sensors
- AR200 Augmented Reality Sensor
- AIS650/700 AIS Transceivers

Raymarine presently investigating potential impacts to other legacy Raystar GPS Sensors, legacy MFDs having internal GPS Sensors, chartplotting products having internal GPS sensors, legacy MFDs having internal GPS sensors (ex. A-Series Classic MFDs, C-Series Widescreen MFDs), and AIS transceivers. As additional information becomes available, this FAQ will be updated accordingly. Should a system's GPS receiver be affected, then most affected systems may be addressed by interfacing a Raystar 150 GPS Sensor to the system.

Update: 25 March 2019 - More details will be released this week. Upon receiving these details from Raymarine's engineering team & program management, this FAQ will be immediately updated.
