If you can find an old Trimble SV6, those all rollover. They are rather limited in the NMEA strings that they output. Most of the early Motorola 6 channel devices have also rolled over.
Or wait until 29 July 2017 and the Thunderbolt rolls over. The Tbolt does not output NMEA, but Lady Heather now has a mode that can generate and echo a NMEA stream from any of the GPS receivers it supports.
The Ublox receivers have a command that lets you set the GPS week. I don't know if they let you set a week that is before the firmware creation date. Unfortunately, Heather does not have a way of sending that command. Perhaps U-Center does?
> I'm looking for one for testing software. Does anybody know a model that has
this problem and/or know where I can get one?
