The SV-GPS-2020 GPS Receiver/Antenna from Dynon Avionics allows existing and new SkyView and Advanced AF-5000 series customers to add a 2020-compliant GPS position for ADS-B Out. As a drop-in replacement for the existing SV-GPS-250 receiver, existing customers do not need to run any additional wires, coax, or install any new boxes in their aircraft. When combined with Dynon’s SV-XPNDR-261 Mode-S transponder, SkyView and Advanced Flight Systems customers meet all the transponder and ADS-B Out requirements. Pilots can also add the SV-ADSB-470 Traffic and Weather Receiver for the best possible situational awareness in their aircraft.
The SV-GPS-2020 is limited to ground speeds of 400 knots and below. To meet the integrity level required for an ADS-B position source, the SV-GPS-2020 needs a stronger GPS signal than the SV-GPS-250 and may not work acceptably unless mounted on the outside of the aircraft.
Along with the SV-GPS-2020, what else do I need for a 2020-compliant system?
You’ll need a SkyView or AF-5000 system equipped with an SV-XPNDR-261 Mode-S Transponder. ADS-B In capability (traffic and weather reception in the aircraft) is not required, so the SV-ADSB-470 traffic and weather receiver is not required for compliance. However, you will want it to receive traffic and weather.
How does the SV-GPS-2020 connect?
The SV-GPS-2020 connects using four wires (two serial, power, and ground).
What is the difference between the SV-GPS-250 and the SV-GPS-2020?
Both are WAAS GPS receivers that update position at 4-5Hz. The SV-GPS-250’s design utilizes high volume commercial GPS components that yield a lower price point ($200). However, this design does not have the documented design data and integrity checking necessary to prove it meets the FAA’s 2020 performance requirements. The SV-GPS-2020 has the design data demonstrating that it meets the FAR performance requirements.
