National Oceanic and Atmospheric Administration nautical charts carry this note; "Warning - The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids." ... Having once encountered a misplaced buoy or a missing daymark or beacon we habitually verify that the aids to navigation we see are where they should be. Yet we willingly assume, withoutany independent verification that the GPS fix displayed on our chartplotter is correct to within the three to perhaps 10-meter precision to which we are accustomed.
June 2009 - eLGPS 1110 by CrossRate - What? Isn't Loran dead? Well, no it isn't, and there might be a couple of good reasons to revisit its functionality.
Three-in-One Antenna
CrossRate Technology combines the best of three crucial elements of security at sea: reliability, heading and accuracy. The eLGPS1110 antenna utilizes Kalman integration technology to combine the positioning sensors for GPS and eLoran in order to provide what CrossRate says is "99.994 percent reliability." eLGPS provides heading information within one degree, even when stationary, and accuracy to less than two meters. The single unit combines three systems into one unit with pole or flush-mount hardware and PC software for configuration.
