The ViaSat-3 is a series of three Ka-band satellites is expected to provide vastly superior capabilities in terms of service speed and flexibility for a satellite platform. Each ViaSat-3 class satellite is expected to deliver more than 1-Terabit per second of network capacity, and to leverage high levels of flexibility to dynamically direct capacity to where customers are located.
