[2][3] They were launched in 2015 and 2016 to provide fast broadband in areas where NBN didn't want to either lay fiber or install enough wireless antennas and offshore.

Each Sky Muster has 101 spot beams,[5][6] which are focused satellite signals which are 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.

[17] The two NBN satellites, Sky Muster (NBN-Co 1A) and Sky Muster II (NBN-Co 1B), were conceived in 2012 under the Gillard Labor government, as part of the original National Broadband Network scheme and NBN Co contracted Space Systems/Loral (SSL) to build and launch the two satellites as part of a total investment costing A$2 billion.
