Dynon SkyView HDX - GPS Receive Performance

SV-GPS-2020 GPS Antenna/Receiver Installation and Configuration
11-8 SkyView HDX System Installation Manual - Revision E
When the SV-GPS-2020 is powered up for the first time, or is powered up
after several weeks or months of not being used, the SV-GPS-2020 may
require several minutes to acquire GPS signals.
The number of satellites in “view” of the SV-GPS-2020 will vary depending on the time of
day, location, etc. Generally, a minimum of six (6) satellites should be shown.
On the GPS FIX STATUS screen, verify the values shown in the table below.

See Table 28: GPS FIX STATUS Satellite Color Explanation (below) for an explanation
of the colors.

Color
Details
Green
Received signal strength is above the desired threshold, this satellite is used in
the position solution.
Yellow
Received signal strength is below the desired threshold, this satellite is used in
the position solution.
White
This satellite is in view, but is not used in the position solution.
Note that GPS FIX STATUS only displays information for the GPS that is set
to POS 1. If you have a second GPS installed, temporarily set that unit to
POS 1 and temporarily set the primary GPS to POS 2.
If, after waiting several minutes, any of the Minimum Values shown in Table
27: Verification of SV-GPS-2020 Adequate Satellite Reception are not shown
(such as illustrated inFigure 72above) it may be necessary to install the SV-
GPS-2020 in a different location on the aircraft.
