AMC-3 (formerly GE 3) is a commercial broadcast communications satellite owned by SES World Skies, part of SES S.A. (and formerly GE Americom, then SES Americom). Launched on September 4, 1997, from Cape Canaveral, Florida, AMC-3 is a hybrid C-band/Ku-band satellite. It provides coverage to North and Central Americas, the Gulf of Mexico, and the Caribbean. Located in a geostationary orbit parallel to the Yucatán Peninsula and Great Lakes, AMC-3 provides service to commercial and government customers, with programming distribution, satellite news gathering and broadcast internet capabilities.[6][7]

In January 2017, the AMC-3 Ku-band payload was sold to Global Eagle Entertainment (GEE), a provider of satellite-based connectivity and media to mobility markets, such as passenger aircraft. GEE purchased all the capacity on the satellite to support aeronautical customers, in particular Southwest Airlines, the company's largest customer, and rebranded the satellite as Eagle-1. The satellite will remain under the control of SES.[8]

Among other satellite TV channels, AMC-3 carries NASA TV.[9]

In the United States, NASA Television's Public and Media channels are MPEG-2 digital C-band signals carried by QPSK/DVB-S modulation on satellite AMC-3, transponder 15C, at 87 degrees west longitude. Downlink frequency is 4000 MHz, horizontal polarization, with a data rate of 38.86 Mhz, symbol rate of 28.1115 Ms/s, and ¾ FEC. A Digital Video Broadcast (DVB) compliant Integrated Receiver Decoder (IRD) is needed for reception.
