The ViaSat-3 constellation is our next generation of ultra-high-capacity, Ka-band satellites, expected to increase our global coverage and network capacity — bringing affordable, high-quality connectivity where, when, and how it’s needed most. When fully operational, the network is expected to enable billions — in homes and businesses, on planes and at sea, and in communities that were once off the grid — to connect with the people and information they need.
The first satellite of the global ViaSat-3 constellation was successfully launched from NASA’s Kennedy Space Center in Florida in 2023. Launches for the subsequent ViasSat-3 satellites are pending.
The ViaSat-3 constellation is expected to deliver 600% more capacity than Viasat’s entire previous fleet — with nearly half of that available in areas around the world that are unconnected or underserved.
Optimized to meet the growing global demand for affordable, high-quality bandwidth, the ViaSat-3 constellation is expected to help foster digital inclusion by enabling online education, telemedicine, and business opportunities for those who need it most, while also providing consumers, businesses, and government the bandwidth to take advantage of opportunity in some of the world’s hardest to connect places.
The ViaSat-3 constellation is expected to help foster digital inclusion around the world for many of the 2.7 billion people who are currently unserved or underserved.
Our network is expected to be available to 99% of the populated world, bringing high-quality, affordable connectivity to people, businesses, and communities — delivering satellite internet to remote communities, connecting militaries in real-time on the battlefield, enabling satellite-to-satellite networking for global, on-demand data access, and providing connectivity for global land, air, and sea routes.
A “beam” describes the targeting field of a satellite signal. It’s aimed at a specific area on the ground, moving data back and forth using radio spectrum.
A satellite’s total bandwidth — or capacity — is shared across all of its beams. To get the highest productivity out of a satellite, it’s important that the bandwidth is available in areas where demand is highest.
Rather than having bandwidth fixed to beams, the ViaSat-3 constellation is designed to move capacity between beams to bring bandwidth when and where it’s needed most — what we call dynamic bandwidth allocation. By anticipating increases in demand throughout the world and move capacity to meet them — giving us the ability to meet dynamic and shifting market demands, help militaries and governments withstand and recover from stressors, better serve our business and residential customers, and provide superior bandwidth economics.
