GPS Week Rollover

Posted on April 1, 2019

GPS Week Rollover is April 6th, 2019 @ 23:59 UTC

GPS satellites send a 10-digit binary message toward Earth with a “week number” counted from 0000 to 1023. Once the maximum coded week of 1024 is reached (which takes 19.7 years), the week number value resets to 0000.

With the wide variety of GPS technology applications in use today, the impact to users will vary depending on the use case, e.g., surveying with a base and rover receiver, machine control, OEM placement, or precision agriculture. Impacts such as slower initialization time and incorrect date records can be expected for some receiver and software combinations if the firmware and software are not updated to the latest available versions. In most cases, an update to the latest receiver firmware and latest versions of software are recommended.
