SkyView SE supports only one unit, either an SV-GPS-250 or an SV-GPS-2020, as a
GPS position source. The installation of a secondary GPS position source is not
supported in SkyView SE. Thus, instructions for installation and configuration of a
secondary GPS position source in this section are not applicable to a SkyView SE
system. If your aircraft requires the use of a secondary GPS position source,
SkyView SE is not recommended.
This section explains the installation and configuration of the Dynon Avionics SV-GPS-250 GPS
Receiver and SV-GPS-2020 GPS Antenna/Receiver Module (High Integrity GPS). After reading
this section, you should be able to determine how to prepare the installation location, mount
the unit, connect the unit to a SkyView display(s), and configure it in the SkyView display.
Information specific to either the SV-GPS-250, or specific to the SV-GPS-2020 references the
individual unit. Information that is applicable to either unit is referenced by “SV-GPS-
250/2020”.
The SV-GPS-250 was part of the introduction of the SkyView system in December, 2009. From
then, through December, 2015, the SV-GPS-250 was the only GPS receiver available from Dynon
Avionics. Thus, any aircraft built prior to January, 2016 that has “all Dynon Avionics” panel likely
includes an SV-GPS-250. The SV-GPS-2020 was released for sale beginning January, 2016.
As of January, 2016, the intended use for the SV-GPS-250 in a SkyView system is:
US pilots – secondary GPS receiver (SV-GPS-2020 is primary) (not supported in SkyView
SE),
US pilots – SV-GPS-250 was installed prior to the availability of the SV-GPS-2020 and are
waiting until closer to 2020 to retrofit / add an SV-GPS-2020, or
Non-US pilots whose aviation authorities do not require a high-integrity GPS position
source for Mode-S transponder transmission – primary or secondary GPS receiver.
The SV-GPS-250 and SV-GPS-2020 are self-contained GPS receivers intended for use with the
Dynon Avionics SkyView system and the Advanced Flight Systems (AFS) AF-5000 system. The
SV-GPS-2020 provides “high integrity” GPS data to the SkyView system that is required by the
FAA 2020 ADS-B Out mandate. The SV-GPS-250 does not provide “high integrity” GPS data to
the SkyView system that is required by the FAA 2020 ADS-B Out mandate. Unlike similar-looking
GPS units, the electronics of the GPS receiver are contained within the unit – there is no
