HaloNet Portfolio For Near-Earth Communications Launched by Viasat
New Modular System Targets Growing Low Earth Orbit Market With Multi-Band Connectivity Solutions
The HaloNet portfolio, a comprehensive system designed to handle communications for the rapidly expanding low Earth orbit market, has been announced by Viasat. The company developed the modular platform through its Government and Defense divisions to serve both military and commercial space operations.
"With today's space environment becoming increasingly complex, customers need agile, reliable and secure communications infrastructure that can support real-time command and control and data transport needs."

The HaloNet system addresses growing demand from government and commercial operators running LEO missions who need reliable ways to transmit data back to Earth while maintaining spacecraft control. Current LEO operations face challenges balancing real-time communication needs with data processing requirements.
Viasat designed HaloNet to connect simultaneously with thousands of space vehicles across all orbital patterns, including polar and retrograde orbits. The system supports missions at altitudes up to 683 miles in LEO and extends to medium Earth orbit operations. The platform combines ground-based antennas with orbital relay systems to create multiple communication pathways. Data transmission rates range from tens of kilobits per second to more than 10 gigabits per second, depending on mission requirements.
"HaloNet is helping transform near-Earth communications, combining our advanced space, ground, and networking infrastructure into a solutions portfolio addressing customer needs," said John Reeves, Vice President of Space and Mission Systems at Viasat Government. "Through HaloNet services, Viasat is providing a one-stop-shop for multi-band, multi-path, secure connectivity and data transport solutions that will enable both government and commercial customers' missions."
The system uses geostationary relay satellites to route data through L-band, Ka-band or optical connections based on mission parameters. Viasat's global network of direct-to-Earth ground antennas provides backup options and additional network resilience.
The announcement comes as the commercial space industry experiences significant growth, with numerous companies launching LEO satellite constellations for communications, Earth observation and other applications. Government agencies also increasingly rely on LEO systems for scientific research and defense operations.
Viasat operates as a global communications provider serving residential, business, government and military customers through satellite internet and connectivity solutions.
