How do you know that the output format used is indeed reflecting the
internal processing in the unit? As others have stated already, the
extra channels can be used to correlate signals and to get around
multipath issues. Maybe they just selected to ever report 12 sats to
be sure not mess up receiving applications?
The 20 channel capability is adjustable with firmware and only represents the full channel bandwidth of the DSP implementation. The design of the unit does not have dedicated channels like most earlier designs. It is not being used in any of the computation of Garmin units and is unlikely to be used in any but very specialized units unless competitive pressure forces it. There are several true 16 channel units out there today however in the consumer space. In the professional units going up to 24 channels by including Glassnos capability.
