Mapping & GIS GPS Week Number Rollover
March 15, 2019

Are you covered for the GPS Week Number Rollover?


As many of us are aware, there is an impending GPS Week Rollover coming on April 6th. Here is a statement released from Trimble.

Trimble Mapping & GIS Handhelds and Receivers

“A GPS week rollover will occur at the end of the GPS day on April 6, 2019, at which time the GPS week will transition from week 2047 to 2048. However, because the GPS message structure broadcasted by the satellites defines the week as at a 10-bit value, the GPS messages will indicate that the week has changed from 1023 to week 0.

Trimble has performed tests using a GNSS simulator to verify that the receiver firmware of our Mapping & GIS handhelds and receivers correctly handle the week rollover in different scenarios.

To prepare for the week number rollover, it is recommended to install the latest receiver firmware version available on the Trimble GIS web page under the Support & Downloads section of the relevant product page, or by visiting Support A-Z for legacy products.”
