WEFAX is a standard data transmission specification used by operators of geostationary meteorological satellites to transmit satellite images and other data in analogue form to low-cost user stations. The format is a derivative of the Automatic Picture Transmission (APT) originally developed for transmission from the polar satellites of the USA.
The international standard broadcast frequency for satellite WEFAX transmissions is 1691,0 MHzMegaHertz (MHz) 10^6 Hz. Some systems, such as EUMETSAT’s METEOSAT, also transmits WEFAX on 1694,5 MHzMegaHertz (MHz) 10^6 Hz.
The composite audio signal is frequency modulated (FMFrequency Modulation) onto 1691.0 MHzMegaHertz (MHz) 10^6 Hz (Channel A1) and 1694.5 MHzMegaHertz (MHz) 10^6 Hz (Channel A2) carriers.
