It is equipped with a WAAS receiverand a DGPS receiver as standard supply. The powerful processorperforms high-speed processing, position fixing and augmentation.It utilizes both WAAS and differential radio beacon correctionmethods.This compact and cost-effective unit offers extremely accurateposition fixes - 10 m for the basic GPS, 3 m where WAAS serviceis available and 5 m with DGPS. It should be noted that DGPS ismore reliable and accurate, as the WAAS system is still currentlyunder development. There is no guarantee of accuracy, integrity,continuity or availability of the WAAS signal. For that reason,the GP-37 runs with DGPS as the default setting in auto selectionmode. If the DGPS signal can not be received for any reason, theWAAS mode is automatically selected. Manual settingis also available.The Display modes include Plotter, two Customizable displays,Steering, Highway and Speedometer Mode. The Steering Displaymode provides an intuitive indication of course to steer and crosstrack-error(XTE). The Customizable display allows you to selectthe display layout so the navigation data you are interested in isdisplayed in large characters.SpeedometerPlotterSteeringHighwayCustomizable displayWAAS (Wide Area Augmentation System)WAAS is a GPS navigation system which applies correction data by means of geostationarysatellites. The US FAA has been testing this system and others using Satellite-BasedAugmentation Systems (SBAS). As the WAAS utilizes the same frequency as the GPS, a singleantenna can receive GPS and WAAS signals. At the moment two Inmarsat GEOs are available,i.e., AOR-W and POR. Similar systems are under development in Japan (MSAS: MSAT SatellitebasedAugmentation System) and Europe (EGNOS: European Geostationary Navigation OverlaySystem). They are said to be fully interoperable and compatible. Major contributors of an error in asingle frequency GPS system is a receiver clock drift and signal delays by refraction. The WAASreference stations on the earth monitor the GPS constellation and route GPS error data to theWAAS satellite via the master earth station. The Inmarsat or communication satellite broadcaststhe differential corrections to users.For more info, visit the FAA web at http://gps.faa.gov
