What is Feeding?

The often used term feeding is used to describe the action of gathering data and sending it to a remote service, usually an application or an aggregator (such as Airframes or ADSBExchange) for further processing.

When you use your SDR to capture aircraft data from the sky and then send it to Airframes, you are feeding data to us. From the perspective of the Airframes service, your receiver station is a feeder because it is feeding data to it. Your feed contains data that was captured by your receiver from aircraft in its vicinity.
