I’m still new to this Raspberry Pi/ADS-B feed, and I have a question. I have two Pi feeds here at Flightaware.
One feed, the data rises rapidly during peak times and lowers normally during non-peak hours. The FlightAware “Coverage Distribution” map also has some areas where more messages are received directionally in some areas and not as much in others. To me, this seems like a normal scenario.
The other feed has several high/low spikes throughout the same time period. A 10k - 20k increase or drop of the message rate within an hour. It is almost as if there is some sort of disconnect in the data stream? Additionally, the “Coverage Distribution” map has no one area that I am receiving more messages than other areas. Pretty much a plain omni-directional coverage area. This does not seem like a normal scenario.
Both feeds are set up exactly the same. Raspberry Pi (with PiAware), Flightaware ProStick and ADS-B antenna (DPD Productions). Why would one be so different than the other? I’m sure geography comes into play but it just seems to be extreme on the one receiver.
