Viasat Triples Global Bandwidth with Full ViaSat-3 Constellation Deployment
Event summary
- ViaSat-3 F2 satellite entered service on September 17, 2026, completing Viasat's global constellation.
- The constellation now provides over 1 terabit per second of throughput across the Americas.
- ViaSat-3 F1 is operational, and F3 entered service in Asia-Pacific in August 2026.
- Advanced beamforming technology dynamically allocates capacity to high-demand areas.
- Viasat claims ViaSat-3 sets new commercial standards for solar power and thermal dissipation.
The big picture
Viasat's completion of the ViaSat-3 constellation positions it as a major player in global satellite communications, with tripled bandwidth supporting aviation, maritime, government, and broadband markets. The deployment comes amid increasing competition in the space connectivity sector, where technological advancements in solar power and thermal dissipation are becoming key differentiators. The integration of Inmarsat's assets further expands Viasat's reach, though regulatory and operational challenges remain.
