The outer ring represents thehorizon around you, the inner ring represents a view above you at a 45° angle from ver-tical, and the center represents directly overhead. Signal Strength Bars for each satelliteare shown just below the Skyview. Satellites and their signals appear as hollow shapesuntil a signal is received and then they appear darkened in. The stronger the signal, thetaller the signal bar.The Wide Area Augmentation System (WAAS) capability produces a more accurateposition fix. When enabled (the GPS mode set to ‘Normal’ and the interface set to otherthan RTCM mode), this feature searches for a WAAS satellite near your location andthen receives data for correcting differentials in the GPS satellite signals and the WAASsatellite numbers (Number 33 or above) display on the Satellite Page. When differentialcorrection data has been received for GPS satellites (number 32 or below), a ‘D’ displaysin the signal bar beneath the skyview. It is helpful to orient the unit antenna toward theWAAS satellite shown in the skyview. To learn more about the WAAS System, access theFederal Aviation Administration web site (http.//gps.faa.gov/).
