The Sky Muster and NBN Co 1B satellites will be part of the high-speed broadband service to rural and remote areas of Australia. The satellites will be operated by NBN Co Limited (NBN Co), which was established to implement the Australian government policy initiative of providing access to high-speed broadband to every household and business in the country via an integrated national network that will use fiber, fixed wireless, and satellite technologies. NBN Co 1A and 1B are both Ka-band, high-throughput broadband satellites that use multiple spot beams in an advanced design that tailors capacity to Australia’s vastly distributed population. When launched in 2015, the satellites will help bridge the digital divide, providing service to some of the most remote places in Australia, as well as its coastal islands and external territories including Norfolk Island, Cocos Island, Christmas Island, and Macquarie Island in the Antarctic.
NBN Co 1A and NBN Co 1B are based on the SSL 1300 platform, which leads the industry in reliability and has been optimized to provide enhanced performance and capacity distribution for broadband missions. The satellites are designed to provide service for 15 years or more.
