About

This page provides a detailed overview of the Optus satellite fleet, operated by the Australian telecommunications company Optus. The satellites are categorized into A, B, C, D, and 10/11 classes, each with distinct specifications and operational histories. The A-Class satellites (A1, A2, A3) were Hughes HS-376 models with a design life of 7-10 years, equipped with 15 Ku-band transponders. They had a diameter of 2.2m and a height of 2.9m (stowed) to 6.3m (deployed). The B-Class satellites (B1, B2, B3) were Hughes HS-601 models with a 10-year design life, featuring 15 Ku-band transponders, 1 L-band transponder, a Ka-band beacon, and a laser retroreflector. Optus C1, manufactured by Space Systems/Loral (SS/L) using the LS-1300 platform, had a 15-year design life and was equipped with 24 Ku-band, 4 (+1) Ka-band, 4 X-band, and 6 UHF transponders, partially funded by the Australian Government for defence and telecommunications. The D-Class satellites (D1, D2, D3) were built by Orbital Sciences Corporation on the Orbital STAR 2 platform, designed for 15+ years of service. D1 had 24 Ku-band transponders and a launch mass of 2350 kg. D2 featured 24 active Ku-band transponders (sixteen 150W, eight 44W) and a launch mass of 2375 kg. D3 included 32 Ku-band transponders (twenty-four 125W primary, eight 44W backup) and a launch mass of 2500 kg. Optus 10, also an SS/L LS-1300 bus, had a launch mass of 3200 kg and was expected to have similar transponder configurations to the D-series. Optus 11 is planned for launch in Q4 2025. These satellites provide broadcast services, two-way voice and data communication, and government services across Australia and New Zealand. The page also details launch dates, operational locations, and notable incidents or failures for individual satellites.
