GPS Source
The SkyView Classic / SE / HDX System Installation Guide contains comprehensive instructions
for physically installing, electrically connecting, and configuring a GPS device to work in a
SkyView system. This guide assumes these steps have been properly executed. You should be
familiar with the information in the SkyView Classic / SE / HDX System Installation Guide
regarding this topic.
SkyView HDX’s Moving Map display depends on the system having a valid GPS source. In the
event of the failure of the primary GPS source used to display the Moving Map, SkyView will
automatically use other available GPS sources that are configured in the system. SkyView
determines which GPS source to use by using the following prioritized list of GPS sources:
POS 1 GPS 1GPS 2GPS 3GPS 4POS 2POS 3POS 4
See the SkyView Classic / SE / HDX System Installation Guide for more information on setting up
GPS sources.
While SkyView HDX can receive and utilize GPS position data from any connected
GPS device transmitting in proper format, those position data are updated at a rate
of only 1 Hz (once per second). Even when another high-integrity GPS source is
connected to SkyView – such as a WAAS IFR GPS navigator – it is preferable to
install the Dynon Avionics SV-GPS-250 or SV-GPS-2020 as the primary position
source. These GPS receivers provide position updates to the SkyView HDX display
at 5 Hz (5 times per second), resulting in the best possible performance of Synthetic
Vision and the moving map.
If you need to check the status of your GPS source in flight, press-and-hold Buttons 7+8 (IN
FLIGHT SETUP MENU) > GPS FIX STATUS.
If you need to check the status of your GPS source when not in flight, press-and-hold Buttons
7+8 (SETUP MENU) > LOCAL DISPLAY SETUP > GPS FIX STATUS.
Moving Map Page Layout
The Moving Map Page as shown in Figure 90 displays a real-time topographical map in Track Up
or North Up mode (depending on user setting). The map is sourced from a database that is
stored inside the display and correlated to your current position using a GPS feed.
