Connectivity

HaloNet is designed to provide simultaneous connectivity to thousands of space vehicles across all orbital inclinations, including polar and retrograde orbits, at any latitude. It supports missions in low Earth orbit up to 1,100 kilometers and medium Earth orbit. The portfolio offers multi-band GEO relay and direct-to-Earth satellite communications services for a wide range of missions.

Craig Miller, president of Viasat Government, said, “Our HaloNet portfolio enables us to continue meeting evolving near-Earth mission communications needs, as well as government customers’ capability requirements for critical scientific and defense missions.”

HaloNet combines space and ground capabilities to deliver unified command, control, and data dissemination. Its offerings include:

  • Telemetry, Tracking, and Command Data Relay Service, providing real-time situational awareness through secure, low-latency L-band links.

  • Launch Telemetry DRS, offering telemetry relay during launch without dedicated downrange stations.

  • High-Capacity DRS, enabling on-demand transmission of large volumes of data via Ka-band.

  • Direct-to-Earth service through Viasat’s Ground Station as a Service platform across six continents.

  • Mobile Command & Control, a field-deployable satellite gateway.

Based on mission requirements, HaloNet uses GEO relay satellites and L-band, Ka-band, or optical links, supporting data rates from tens of kilobits per second to over 10 gigabits per second. Its global DTE ground antennas add resilience, making the portfolio a flexible solution for diverse mission needs.
