[time-nuts] DATUM 9390 Info wanted

[Björn Gabrielsson]

Don & Rob,

>From back in my memory - I have a feeling I have read - that some 9390s
GPS receivers had trouble with GPS week rollover bugs. Not the orginal
1024 weeks but they were programmed to work "within" a 1024 week window.

I am sure there are time-nuts with more accurate information.
