Fig. 21aFig. 21b21Sky View and Signal Strength BarsThe sky view and signal strength bars give you an indication of what satellitesare visible to the receiver, whether or not they are being used to calculate a positionfix, and the signal quality. The satellite sky view shows a bird’s-eye view of the posi-tion of each available satellite relative to the unit’s last known position. The outer cir-cle represents the horizon (north up); the inner circle 45º above the horizon; and thecenter point directly overhead. You can use the sky view to help determine if anysatellites are being blocked, and whether you have a current position fix (indicatedby a ‘2D NAV’ or ‘3D NAV’ in the status field) (Fig. 21b). You can also set the skyview to a track up configuration by changing the “orientation” option on the MapPage. (See p. 67 for setup instructions.)When the receiver is looking for a particular satellite, the corresponding signalstrength bar will be blank and the sky view indicator will be highlighted. Once thereceiver has found the satellite, a hollow signal strength bar will appear, indicatingthat the satellite has been found and the receiver is collecting data from it (Fig. 21a).The satellite number in the sky view will no longer appear highlighted. As soon asthe GPS II+ has collected the necessary data to calculate a fix, the status field willindicate a 2D or 3D status.
