ADS-B

ADS-B (Automatic Dependant Surveillance – Broadcast) is a system for tracking aircraft that relies on individual aircraft “squittering” their position and other data automatically every second or so on the SSR response (Secondary Surveillance Radar) frequency of 1090Mhz.

There are now low cost receivers available as a USB Dongle that are based on Software Defined Radio (SDR) technology. We now have two sites receiving ADS-B replies. Jeff VE3EFF has set up a receiver at the STP site that is continually “listening“ and dumping data.  Robin VE3UIX also has a site with a higher antenna and hence wider coverage.  Clink on the links to see aircraft in the area. Data from Robin’ s station is continuously sent to Flight Aware to augment their global system. Google Flight Aware to  see worldwide aircraft tracks.
