Viasat Unveils HaloNet Capability Portfolio for Near-Earth Communications and Beyond: Modular Set of Capabilities with Unified Space and Terrestrial Connectivity Architecture

Viasat unveiled its HaloNet portfolio, a modular set of capabilities for near-Earth communications and beyond. The portfolio offers space-to-ground connectivity and relay solutions for resilient and responsive data transport. HaloNet combines the best of Viasat's space and ground capabilities to deliver a unified approach to command, control, and data dissemination. The capabilities include Telemetry, Tracking, and Command (TT&C) Data Relay Service, Launch Telemetry DRS, and High-Capacity DRS. HaloNet is designed to provide simultaneous connectivity to thousands of space vehicles across various orbital inclinations, serving missions in LEO up to 1100 km and in medium Earth orbit.

Title: Viasat Unveils HaloNet Portfolio for Enhanced Near-Earth Communications

Viasat, Inc. (NASDAQ: VSAT), a leading global satellite communications company, has announced the unveiling of its HaloNet™ portfolio, a modular set of capabilities designed to transform near-Earth communications. The HaloNet portfolio unifies space and terrestrial connectivity into a cohesive service offering, addressing the evolving needs of both government and commercial low Earth orbit (LEO) operators [1].

The HaloNet portfolio is built on a next-generation connectivity architecture that provides flexible, multi-orbit network and data services tailored to specific mission requirements. It offers simultaneous connectivity to thousands of space vehicles (SV) across various orbital inclinations, including polar and retrograde orbits, at any latitude. This capability extends to missions in LEO up to 1100 km and in medium Earth orbit [1].

Key features of the HaloNet portfolio include:

1. Telemetry, Tracking, and Command (TT&C) Data Relay Service (DRS): This service provides real-time situational awareness and connectivity with spacecraft through secure, low-latency links via Viasat’s L-band network, enabling satellite operators to access the satellite and data they need when they need it [1].

2. Launch Telemetry DRS: This service offers real-time telemetry data relay during the launch phase through Viasat’s L-band network without the need to build or lease dedicated downrange ground stations. It ensures reliable connectivity from ignition to orbit for launch providers [1].

3. High-Capacity DRS: This service enables the transmission of large volumes of data, such as full-motion video and high-resolution imagery, on demand without prescheduling, through Viasat’s Ka-band network. Global coverage ensures continuous access wherever a customer’s spacecraft travels [1].

4. Direct-to-Earth (DTE) Service: This service provides direct-to-Earth data services through Viasat’s Ground Station as a Service (GSaaS) platform, delivering high-performance TT&C and payload downlinks via a global ground station network spanning six continents [1].

5. Mobile Command & Control: This field-deployable command and control platform via a self-contained mobile satellite gateway supports secure TT&C data transport from virtually any location [1].

HaloNet is designed to meet the agile, reliable, and secure communications infrastructure needs of today's emerging LEO operators. It combines Viasat’s advanced space, ground, and networking infrastructure into a solutions portfolio that addresses customer needs, providing a one-stop-shop for multi-band, multi-path, secure connectivity and data transport solutions [1].

The HaloNet portfolio leverages GEO relay satellites to dynamically deliver data, using L-band, Ka-band, or optical links with data rates ranging from 10’s of Kbps to more than 10 Gbps for secure data dissemination on demand or pre-scheduled. Viasat’s global DTE ground antennas provide increased optionality and further resilience [1].

Viasat’s President, Craig Miller, stated, “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. Our HaloNet portfolio enables us to continue meeting these evolving near-Earth mission communications needs, as well as government customers’ capability requirements for critical scientific and defense missions” [1].

John Reeves, Vice President of Space and Mission Systems, Viasat Government, added, “HaloNet is helping transform near-Earth communications, combining our advanced space, ground, and networking infrastructure into a solutions portfolio addressing customer needs. 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” [1].
