GPS MODULE REPLACEMENT
Europa-T, Libra, Janus
These instruments will be affected by the Week Number Roll Over issue as early as October 28th, 2019 and no later than November 15th, 2021. The best way to determine if the instrument is affected is to get the GPS Module serial number from the label on the device.
Given that this may be difficult to obtain for equipment remotely deployed, we summarized the estimated Week Number Roll Over date for the instruments as per below:
Cygnus:
Serial Number <380 will be affected on October 28th, 2019
Europa-T:
Serial Number < 360 will be affected on October 28th, 2019
Serial Number > 360 but less <430 is likely OK until November 15th, 2021.
How to update the GPS Receiver Module
The GPS Module Model number is on a label on the bottom side of the module which requires the module to be removed from the assembly.
