As Shawn wrote, the maximum number of satellites can bee 12. The additional 
channels of a receiver are used to receive some of these 12 with week 
signals twice or even more. Think of these 20 channels as 20 individual 
receivers. The unit can use more than one of its channels to receive a 
satellite. In other words a certain satellite is received with several 
receivers simultaneously. This increases the sensitivity of the unit. Due to 
the nature of digital signals and the phase modulation scheme of the gps 
system this works in dead. If a data bit cannot be detected by one receiver 
there is a certain chance that it will be detected by the second channel. By 
the way, the holux m1000 - a very new unit - uses 32 channels. I got mine 
yesterday. And it is more sensitive than a typical SiRf3 Unit.
