See page 35.GPS Tab— the “Info” submenu tab provides a visual reference of satellite acquisition, receiver status, andaccuracy. The status information gives you an idea of what the receiver is doing at any given moment. Thesky view and signal strength bars give you an indication of what satellites are visible to the receiver andwhether or not they are being tracked. The signal strength is shown on a bar graph for each satellite, withthe satellite number below. As the receiver locks onto satellites, a signal strength bar appears for each satel-lite in view. The progress of satellite acquisition is shown in three stages:• No signal strength bars— the receiver is looking for the satellites indicated.• White signal strength bars— the receiver has found the satellite(s) and is collecting data.• Green signal strength bars— the receiver has collected the necessary data and the satellite(s) areready for use.As soon as the GPSMAP 3006C/3010C has collected the necessary data from the best satellites inview to calculate a fix, the status field indicates “Ready For Navigation” in the Status field. The unit thenupdates the position, date and time.You can use the sky view to help determine if any satellites are being blocked, and whether you havea current position fix (indicated by a “Ready For Navigation” in the Status field). The sky view shows abird’s-eye view of the position of each satellite relative to the receiver’s last known position. The outer circlerepresents the horizon (north up), the inner circle 45º above the horizon, and the center point a positiondirectly overhead. You can also set the sky view to a ‘Track Up’ configuration, causing the top of the skyview to align along your current track heading.Main Menu: GPS Tab
