Transmitter corrections

Where each transmitter's signal really is, from passes labelled as its signal in the viewer: its centre against its SatNOGS DB listing (for FSK, between its two tones), the receiving station's own offset taken out, and how many seconds its satellite runs against its elements. Two passes or more within 1 kHz of each other make a correction consistent: those are the ones to send to SatNOGS DB. The search looks for each transmitter here, with the station's offset put back. As JSON: /api/v1/corrections.

Stations

A station's own frequency offset: the median offset of the strong carriers it hears, most transmitters being where they are listed. A receiver whose reference is off reads every signal off by the same ppm, so it is taken out of the transmitters' offsets below (each pass also shows what the station received). Offsets at a station locked to GPS are the satellites' own.
