Can anyone explain to me what a "dedicated 71-point GPS module" which is a 0.00 option on a Panasonic Toughpad I am looking to buy? I believe that the brand name is a "U-blox M8" module. Is this something that will increase my access to different satellites, or does it just improve accuracy? I spend some time in deep forests and canyons, where I sometimes loose a signal for a while. Would this potentially help this, or is it a waste of money for me? Also, would this module allow others to track my location if I choose to allow that? Where could I find out some more info on this module? I googled Ublox, but cant find anything about a 71 point GPS module. Thanks!
