ADS-B Update

[Grahame Hutchison]

Since moving to the Eastern Suburbs, my son and I have now setup a network of three ADS-B stations around Sydney, with all the data being combined on 16Right ADS-B.

I have two Stations, one on the Northern Beaches (AirNav Radar Box), one in the Eastern Suburbs (Kinetics SBS-1), and a friend has another Station west of the airport (Kinetics SBS-3). The combined reception polar plot of
the three Stations looks like this.



The reception Polar Plot graph for the Eastern Suburbs Station looks this, and tonight we received a Melbourne to Wellington flight, ANZ850 ZK-OJH, at a range of 600.2 nautical miles (1111.5 km), at FL350. This Station is
using a Kinetics SBS-1 receiver, and my Home Made Coaxial Co-linear antenna, fixed to the inside of a south facing lounge room window. Pretty happy with that result. The best pickup by this station was at a range of 687nm
(1272.3 km). The theoretical maximum reception range for an ADS-B signal is around 230nm, because of the curvature of the earth.
