I subscribe to the Marine Electronics edition of the Ocean Navigator Email Newsletter. In the issue I received this morning was an article by Larry McKenna discussing the Euroopean version of GPS, called Galileo, along with some comments on the US version of GPS. Included in it was the following: >>>>>> Finally, for no other reason than you can't contest the results of a head-to-head comparison of marine electronics, I offer this little tidbit from Don White in Ontario about WAAS: While researching for a basic GPS course I was writing, I had the opportunity to have a couple of WAAS-capable Garmin GPSs and a Magellan Meridian Marine unit to compare. Standing in my driveway with the GPS76 in one hand and the Meridian Marine in the other, the Magellan will pick up and lock on to both the Atlantic West Inmarsat (54 degrees west) and the Atlantic East Inmarsat (15.5 degrees West). The GPS76 could not even pick up the Atlantic West satellite at 33 degrees above the horizon! The Garmins would show (estimated position errors) of 26 to 55 feet; the Magellan was stable in WAAS mode, about a 9-foot error. Neither of the two other Garmin e-Trex units could pick-up the WAAS satellites. I suspect the antenna design was (is?) the culprit. >>>>>> Rick Quarles Barric II, Nordic Tug 32-147 New Bern, NC
