SV-GPS-250/2020 GPS Receiver Installation and Configuration
SkyView System Installation Guide - Revision AA 8-15
(US only) Additional configuration required for SDA/SIL=1…
… required for continued reception of ADS-B Traffic (early 2016)
The following is only applicable to US pilots whose aircraft is equipped with an SV-GPS-250 (but
not an SV-GPS-2020), SV-XPNDR-261/262 (or other Mode-S / ES transponder), and SV-ADSB-470
(ADS-B In receiver).
Prior to 2016, the FAA transmitted TIS-B to aircraft in US airspace who transmit SIL/SDA=0 (GPS
integrity), allowing those aircraft to receive targeted “ADS-B Traffic” specific to their aircraft. In
early 2016, the FAA will discontinue transmitting TIS-B to aircraft in US airspace who transmit
SIL/SDA=0.
Prior to SkyView Software v14.0, SkyView systems equipped with an SV-GPS-250 transmit only
SIL/SDA=0. In SkyView Software v14.0 and later, SkyView can be configured to transmit
SIL/SDA=1 or SIL/SDA=0. When set to SIL/SDA=1, this allows aircraft in US airspace equipped
with an SV-GPS-250 to continue to receive TIS-B / ADS-B Traffic through December 31, 2019. If
you are a US pilot and have an SV-GPS-250 (but not an SV-GPS-2020) on your aircraft,
information on configuring your SkyView system for SIL/SDA=1 is found in SV-XPNDR-261/262
Installation and Configuration.
Additional Configuration Required for Compliance with FAA 2020 ADS-B Out
Mandate
This section (above) deals with installation and configuration of the SV-GPS-250
and SV-GPS-2020 only. However, installing the SV-GPS-2020 is only part of what is
required to be compliant with the FAA 2020 ADS-B Out mandate. Specifically, next
steps include:
Update your SkyView system to Software v14.0 (or later).
Ensure that your SV-XPNDR-261 has Software SW02.08 (or later), update
your SV-XPNDR-261 if required.
Change the SV-XPNDR-261’s source of GPS data to the SV-GPS-2020.
For the details on the transponder changes, and explanation of overall compliance
with the FAA 2020 ADS-B Out mandate, see the SV-XPNDR-261/262 Installation
and Configuration section.
