I don't think he is talking about the PADS portable unit. I believe he is talking about the new ADS-600-EXP that is specifically designed for the Experimental and LSA aircraft that meets the 2020 FAA Mandate. It's on NavWorx website listed under Experimental Transceiver Models. It says it's capable of meeting the mandate, but I think that is still going to require a "WAAS GPS Certified Position Source", which would add substantially to the cost. Should be an interesting unit to keep an eye on.
