Thread: Humminbird GPS Question

This was the answer explaining the new Hi accuracy receiver/ant from one of the side sites better viewers, not a HB mod.........

RE: [sideimaging] New GPS antenna?


This receiver supports both GPS L1 and Galileo L1 signals (each having about 30 satellites, plus the WAAS sats, and I'm not sure, but it may use ground based stations as well) adding up to way over 50 even though you'll never see more than 50% at anyone time. The 50 channels refers to the number of parallel radio contacts it can maintain, while it can aquire 32 channels at a time, and only ever use 16 actual satellites to compute a position (from the data sheet). The benefit being that it can switch new satellites in instantly as they come into view (because it was tracking them even when they had poor signal strength), and track older ones longer in case you (or they) move back into view.

The above was taken from a U-blox document. I'm not exactly sure what it all means but the bottom line is the high degree of accuracy. And from other sources I understand it has a very fast aquisition time.

Yes supposed to be 3 channels to each satellite so I have been told, Jax

That was what my original thought was ,since it has the extra channels locked on to a stronger signal ,would it (the GPS) be able to update quicker?, Called Hb there is 2 new receivers 1 being the 50 channel and the other called the high accuracy receiver . and the anwser to my question about speed was no as Wiskers said and Pan man, it only gets you closer to the marker . So now I need to leaern to use my ex legend for gps .Great
