It's not a timing receiver. SiRF has a huge chunk of the low cost market. Their receiver is sensitive, but it's horrible for timing unless you have a non-USB version so you can get the PPS signal. The problem is wander. (With my timing hat on, I'd call it a firmware bug.) By wander I mean very low frequency jitter. It's low enough that you can't filter it out by averaging a reasonable number of samples. http://www.megapathdsl.net/~hmurray/ntp/GPSSiRF-off.gif -- These are my opinions.
