Sam, they admit the problem but claim that the wrong dates dont affect processing. Well that is crap. If you use Rinex files then you are stuffed because they use dates for matching records!!! There goes your ability to use differential corrections.
Their excuse for producing incorrect data is that it doesn't matter!!!



Because of the GPS Week Number Rollover, it is impossible with the current
navigation message to determine the correct date for more than 1024 weeks
(19.6 years), with out an external date source or an internal clock set by
the user... no matter who is the manufacturer.

I understand your frustration, Roman... and share it. Many manufactures of
data loggers and survey equipment didn't expect some units to be in service
long enough to run into the GPS Week Number Rollover problem.

Anybody else annoyed by the failure of Trimble to properly fix the Y2K problem with their GeoExplorer GPS units? They claim that the wrong date doesnt affect processing. This is crap. If you are using Rinex files for differrential correction then the date is scattered throughout the records.
I am amazed that in litigation crazy US that Trimble have been allowed to get away with this. Didnt Congress pass a law mandating Y2K fixes?
