HaloNet™

Connect every mission phase — within the Halo
Viasat’s HaloNet™ surrounds your mission with resilient, secure, and scalable communications — from launch to orbit to Earth.

Discover how HaloNet forms a seamless ring of connectivity around your mission — integrating relay, ground access, and field operations into one adaptive architecture.

Flexible capabilities. One halo.​

HaloNet simplifies space communications by bringing mission-critical functions into one interoperable system. Whether you're managing launch telemetry, downlinking sensor data, or extending operations into the field, HaloNet provides complete command and control — backed by trusted coverage and modular access.​

Secure, resilient TT&C
Telemetry, tracking, and control you can count on

Maintain real-time situational awareness through every orbit. HaloNet provides persistent TT&C with secure, low-latency links and IP continuity. Choose between on-demand or continuous models, tailored for operational resilience across the mission lifecycle.

Launch telemetry support
Reliable connectivity from T-0 to orbit

HaloNet delivers near-real-time telemetry during the critical launch phase — without the need to build or lease downrange ground stations. It’s a lighter, faster, more reliable way to stay connected from ignition through ascent.

High-throughput data relay
Real-time, high-volume data delivery

Transmit large volumes of data — on demand, without pre-scheduling. HaloNet supports up to 50GB per orbit with low latency, making it ideal for full-motion video, high-res imagery, and scientific sensors. Global coverage enables continuous access wherever your spacecraft orbits.

Direct-to-Earth antennas
Automated payload access — Earth-side

HaloNet provides additional flexibility using our globally distributed ground network for TT&C and high-volume data downloads to spacecraft in LEO, MEO, GEO and beyond.

Mobile command & control
Deploy mission operations virtually anywhere

For missions that require mobility, HaloNet offers a field-deployable command and control platform. This self-contained mobile gateway is designed to support telemetry, tracking, and command from virtually any location.

Unified where it matters. Flexible where it counts.

Every HaloNet capability is part of a cohesive architecture — designed to work seamlessly together, but available individually to meet your mission’s specific needs. Choose the features you need, scale as required, and operate with confidence across domains.
