Aircraft locations differ from FlightRadar24



Quite new to this but as a Raspberry Pi enthusiast I fancy building an ADS-B receiver and share data.

Can you try and clarify something for me; I live close to Heathrow’s flight path and often see aircratf on the live map approaching my location and Flightradar24 appears very accurate. Flightaware’s map however seems to not show many aircraft and not update too much.

As this mapping is done via the web why should FlightRadar24 and Flightaware differ?



The data you are seeing on the website served by your Raspberry Pi is observations your receiver is picking up. The data you are seeing on FR is a compilation of data from multiple sources. There is a data screen on FR that indicates the source of the data.
