Tom,
It's basically a non-issue for timing receivers, because as you say you never see abov 12-13 SV's under even the best conditions. The one application where a 20 channel receiver "could" make a difference is in cold start performance as you have more channels to search with. This is always a hot button issue with navigation systems, such as in your car, etc. For the most part the subject is almost moot because the search algorithms of the newer receivers work much better. They come up plenty fast with 12 channels.

TNX. Those are Glonass + GPS receivers. /tvb References 1. http://www.synergy-gps.com/ _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
