Through the efforts of Mike Abernathy, Mark Hawkins and the late Renny Rozzoni, the Albuquerque Soaring Club has installed several FlightAware receivers and a couple of OGN Trackers in and around the Estancia Valley (Moriarty Airport- 0E0). the FlightAware hardware is available from FlightAware at a very reasonable cost (and even for free, if the area is underserved by the FlightAware network).

FA tracks Mode C, Mode S and ADS-B. With several receivers and small computers sending the signals to FlightAware, we are seeing all transponder and ADS-B traffic in over a 200 mile radius. There is a 42 inch TV screen in the Moriarty Airport office that displays both the transponder and ADS-B contacts, giving ID, altitude, A/C type, speed and heading. Mode C and S positions are derived from "multilateralization" of signal strength received by three or more installed antennae.

The OGN trackers are similar in cost. (Under a few hundred dollars each, including antenna, mounts, cables, mini-computer, etc.) These receivers only pick up the signals produced by PowerFlarm and compatible third party transmitters. Contacts from the OGN network are displayed in a separate window on the big screen. Because the PowerFlarm signals are mush weaker, the range is very limited, but we seem to be able to pick up PowerFlarm equipped gliders fairly reliably out to 50 km or so. Adding additional units will spread the contact area. We hope to be able to cover about a 100 mile radius.

Each installation is funded by a club member. So far, Mike Abernathy, Mark Hawkins, Bill Hill and Mark Mocho have paid for installations of either FlightAware, OGN or both The most remote installation is 100 miles north at Taos.
