Sky Muster I (NBN-Co 1A) communications satellite was built by Space Systems/Loral (SS/L) and launched by launch operator Arianespace on October 1st, 2015 from the Guiane Space Center in French Guiana. The satellite was launched in a dual launch with Argentina’s ArSat-2 from satellite operator Arsat. Sky Muster I became operational in April 2016 and operates in geostationary orbit of 140° East, north of Australia.

The Sky Muster satellites have 101 spot-beams which are focused satellite signals specially concentrated in power and cover a specific geographic area. The electromagnetic Ka-band spot beams are used to carry information from the End-users equipment on the ground to the satellites. Each satellite offers 80Gbps of bandwidth. The two satellites will provide high-speed brodband service to 400,000 Australian homes and businesses in rural and remote Australia and were designed to provide service for at least 15 years.
