SV-ADSB-470 Traffic Display Capabilities (US Only)
The SV-ADSB-470 works in tandem with your SV-XPNDR-26X transponder modules to provide
the FIS-B traffic picture around your aircraft when you have both products. This is enabled by
the following bidirectional data link capability:
1.
The SV-XPNDR-26X has ADS-B out capability via its 1090ES capability.
2.
The SV-ADSB-470 contains an ADS-B 978MHz “UAT Band” receiver that can see other
traffic – both ADS-B equipped targets AND radar targets - in the following manner:
a.
ADS-B equipped aircraft: The SV-ADSB-470 can detect traffic transmitting ADS-B
out messages via 978 MHz directly.
b.
TIS-B: Additionally, the FAA’s ADS-B TIS-B service, seeing your transponder’s
1090ES ADS-B out transmission - but knowing that your aircraft only has 978
MHz input capability via the SV-ADSB-470 - assembles a traffic portrait of all
traffic that it knows about that are within 15 Nm and +/- 5000 ft of your aircraft.
This includes:
(1)
ADS-R (rebroadcast) targets: The FAA ADS-B system will rebroadcast all
of the 1090ES ADS-B-equipped targets onto the 978 MHz band for your
benefit
(2)
Radar targets: Any targets that the FAA’s radar system is aware of via
approach, center, and other radar facilities.
The end result: your aircraft sees the vast majority of the aircraft that can possibly be a factor.
Since SkyView participates in the ADS-B system via the SV-XPNDR-26X’s ADS-B out capability, it
receives all of the traffic that the FAA knows is around your aircraft. In contrast, “receive only”
ADS-B traffic solutions aren’t able to see the all traffic (such as radar-only targets) because they
are not able to request traffic data from the FAA ADS-B ground stations.
Although weather and TFR information (FIS-B services) is available any time the SV-
ADSB-470 is in an ADS-B ground station coverage area, ADS-B FIS-B traffic is only
available if an SV-XPNDR-26X is installed and is providing ADS-B out position reports
into the ADS-B system.
Useful information about the ADS-B traffic and weather systems can be found in
the FAA AIM:
