Touch GPS: 51 Channel GlobalTop G66 Announced

I must confess that I didnt think we’d ever go beyond the 32 Channels that a few of the new GPS receivers like the Travel Recorder are sporting.
However: GlobalTop is about to announce their amazing 51 Channel GPS receiver.
This one is called the G66 Touch GPS and because of its extreme thickness is aimed specifically at the mobile market.
It also comes equipped with Smart2Go software to try out. I reckon that is a smart move by itself!
This Bluetooth baby has a battery endurance of 20 hours which is nothing to sneeze at.
DigitalReviews.net will be bringing a full report on this Touch GPS in a few weeks time as they have been promised one of the first review units.
See here for specifications.

Looking at the specs it appears it only runs on the US GPS system, not any of the other systems and only on the standard 1575MHz band. So would someone tell why 51 channels is better? Normally each channel relates to a satellite that the receiver can get data from and is actually done with corellators in the chip that look for the digital data sequence of the satellite of interest. To add channels it is simply more transistors on the chip. Last time I check there were 27 GPS satellites in orbit. 3 spares and 24 active. So at any time there is normally 12 on your half of the world. This is why most GPS receivers were designed with 12 channels. If you use suitable software to look at the extra data in the NMEA sentences you can get a plot of where they all are in the sky relative to you and what the signal strength is. In normal operation it very unlikely that 12 satellites can be ’seen’ at any one time. So 51? Is there something I’m overlooking? To be fair the 20 hours is impressive, if it’s true. If I was paying I would look at how the -158dBm sensitivity compares with other units.
