Hi Eugene, the extra channels usually come on more modern GPS receivers that also give you sometimes much higher sensitivity, much faster lock time, less 1PPS jitter, sometimes WAAS/SBAS capability, and last but not least more redundancy and better performance in environments with multipath. Our FireFly units see 16 Sats and more typically at some point during the day. A couple of those sats are WAAS sats, and these don't count for the position fix. These modern GPS receivers use up to 2 Million hardware correlators to track the sats. In short, more Sat channels usually means a higher performance GPS receiver is being used. bye, Said In a message dated 11/26/2010 13:20:03 Pacific Standard Time, [email protected] writes:
But I am still academically curious about the impact of more channels of satellites? What is the value of these extra sats?
