ViaSat 3 [ViaSat]
The ViaSat 3 series of high capacity broadband satellite for ViaSat Inc consists of three satellites for global coverage.
Each ViaSat-3 class satellite is expected to offer over 1 Terabit per second (Tbps) — or 1,000 Gbps — of total network capacity to deliver a global broadband network with enough bandwidth to deliver affordable, high-speed, high-quality internet and video streaming services.
The new first of the news spacecraft for the American market is scheduled to launch in late 2019 or early 2020 and is expected to provide more than 15 years of service life. The second satellite for EMEA will follow soon after. The first two busses were were firmly contracted with Boeing in July 2016 for ViaSat 3.1 and ViaSat 3.2. The third satellite was contracted in February 2019.
ViaSat 3.2 was originally to be procured jointly with Eutelsat, but in May 2018, Eutelsat dropped out of the joint venture.
One satellite was booked on an Ariane-5ECA rocket, while another will be launched on an Atlas-5(551) launch. Another launch contract was awarded to a Falcon-Heavy (Block 5)(ex). The first three satellites were to be launched from 2020 to 2022. The Arianespace launch contract was in June 2019 changed to an Ariane-64 rocket for a 2021 launch. Due to the COVID-19 pandemic, the initial launch date slipped to 2023. Due to delays of Ariane-6, the third was moved off this launcher.
The first satellte, ViaSat 3.1 (ViaSat 3 Americas), was launched in May 2023 on a Falcon-Heavy (Block 5)(ex). It succssessfully reached geostationary orbit, but experienced a major antenna-deployment anomaly that may materially impact the performance of the ViaSat-3 Americas satellite. After one month, the issue has not yet been resolved.
