SYSTEM OVERVIEW
• GPS Satellite Signal Strengths
The GPS Status Page can be helpful in troubleshooting weak (or missing) signal levels due to poor satellite
coverage or installation problems. As the GPS receiver locks onto satellites, a signal strength bar is displayed
for each satellite in view, with the appropriate satellite PRN number (01-32 or 120-138 for WAAS) below each
bar. The progress of satellite acquisition is shown in three stages, as indicated by signal bar appearance:
- No signal strength bar—Receiver is looking for the indicated satellite
- Hollow signal strength bar—Receiver has found the satellite and is collecting data
- Solid signal strength bar—Receiver has collected the necessary data and the satellite signal can be used
- Checkered signal strength bar—Receiver has excluded the satellite (Fault Detection and Exclusion)
- “D” indication—Denotes the satellite is being used as part of the differential computations
Each satellite has a 30-second data transmission that must be collected (signal strength bar is hollow) before
the satellite may be used for navigation (signal strength bar becomes solid).
1.7 ACCESSING G1000 FUNCTIONALITY
MENUS
The G1000 has a MENU Key that, when pressed, displays a context-sensitive list of options. This options list
allows the user to access additional features or make settings changes which specifically relate to the currently
displayed window/page. There is no all-encompassing menu. Some menus provide access to additional
submenus that are used to view, edit, select, and review options. Menus display ‘NO OPTIONS’ when there are
no options for the window/page selected. The main controls used in association with all window/page group
operations are described in section 1.3. Softkey selection does not display menus or submenus.
Navigating the Page Menu Window
1) Press the MENU Key to display the Page Menu Window.
2) Turn the FMS Knob to scroll through a list of available options (a scroll bar appears to the right of the window
when the option list is longer than the window).
3) Press the ENT Key to select the desired option.
4) The CLR Key may be pressed to remove the menu and cancel the operation. Pressing the FMS Knob also
removes the displayed menu.
