"The product will not report the correct extended GPS week number after the Feb,13th 2016. After the rollover to week #860, the thunderbolt will not make position for 2 hours, because the Ephemeris data on the GPS receiver being consider incorrect. The module will work fine after this 2 hours."
Have the Motorola Oncore/Navman/Jupiter receivers also been checked for this condition? Strange that at least 3 independant firmware trees/development teams should chose the same magic wk860. I guess that someone with both affected non-trimble receivers and a gps rf simulator would need to spend some time on this. -- Björn <div>-------- Originalmeddelande --------</div><div>Från: Martin Burnicki <martin.burni...@burnicki.net> </div><div>Datum:2016-02-26 09:32 (GMT+01:00) </div><div>Till: time-nuts@febo.com </div><div>Rubrik: Re: [time-nuts] GPS Outage </div><div> </div>Mark Sims wrote: >> When is some organization going to explain what happened in February for >> almost two hours starting at 00:16 GMT?

The January 26 issue was due to faulty data sent by the satellites, which caused GPS receivers to apply a wrong UTC correction which caused the UTC time to be off by 13.7 us. As explained by Luc Gaudin from http://naelcom.com (who obviously sell Trimble GPS receivers) the February 13 issue was indeed just a Trimble firmware problem.
