Also known as G-15, Galaxy 1RR
24 C-band transponders and L-band payload for GPS navigation to in-flight aircrafts. Covers North America, Alaska, Hawaii and Caribbean. The satellite was restored to operational state after anomaly and is currently in operation at 133 West position. In August 2022 Intelsat again lost the ability to command its Galaxy 15 satellite after an anomaly caused by a space weather event. The anomaly caused the loss of commanding links, which lead to the satellite drifting off its station. In September the communications payload was shut down to avoid interference. The satellite was already to be replaced by Galaxy 33 under the C-band transition program.
