I realize that it might NOT affect us but still, be aware.
There is a massive GPS issue that happened on 28th of July all over the world related to week number rollover. Lots of GPS-dependant equipment was affected and a lot of companies are having losses.
Here is an extract from one of the communities:
Dear MTNet colleagues,
This mail was posted to all of you still after the GPS week number rollover problem was identified but unfortunately did not pass, I repeat:
We found that some of GPS modules in LEMI-417 stations as well as in LEMI-018 magnetometers which some of you have, may be affected by the GPS week number rollover problem (e.g. https://www.gps.gov/cgsic/meetings/2017/powers.pdf)
It means that from April 7, the GPS reported date may not be valid: mostly all our stations will work correctly, except few stations which contain EB-500L GPS module. With such a module the station will still work, but the date and time will be wrong. We have to stress that this problem will not appear until you re-start electronic unit - if permanently working, then all will be good.
As soon as you switch it off, the problem may appear (if GPS module EB-500L is inside).
Many other units were affected, even the ones with Trimble chips. So, beware and safe flying!
