SatNOGS

Pull recordings and decoded telemetry from a worldwide network of volunteer satellite ground stations.

Notes. Site says the network is open to anyone, but only station owners (and operators/moderators) can schedule new observations; ordinary registered users can only browse and download. Site does not state a price; free is inferred from 'open to anyone'.
