GPS protocol: The next week number rollover next year
Posted: 12 April 18 9:31 am
From https://ics-cert.us-cert.gov/sites/defa ... S_2019.pdf:
In the GPS protocol, the week number field is a ten bit value. So every 1024 weeks it will return to zero.
Week 0 is 5 January 1980. And 21 August 1999. And will be 6 April 2019.
So don't be surprised if your GPS will display the wrong date next year.
