Viasat Inc. stands at the forefront of satellite communications, delivering secure, high-capacity connectivity solutions spanning aviation, maritime, defense, and commercial sectors. With a robust global presence, the company continuously develops advanced space and ground network infrastructures. Its recent initiative to expand polar connectivity using its GX10 satellites marks a decisive move to bridge the digital divide in the Arctic.

As polar regions grow in geopolitical and economic significance—from shipping lanes emerging in the thawing Arctic Ocean to expanding scientific and defense operations—uninterrupted communication has become non-negotiable. Traditional GEO networks fail to adequately cover the high latitudes, leaving critical sectors underserved.

Viasat’s GX10A and GX10B satellites, developed in partnership with Inmarsat before the acquisition, go beyond legacy limitations. Positioned in highly elliptical orbits, these satellites provide consistent broadband coverage above 65° North latitude—the first global mobile broadband service with full Arctic reach. By deploying GX10, Viasat enables real-time data exchange and mission-critical operations in some of the planet’s most challenging environments.

Driving Global Connectivity: Viasat’s Mission and Expanding Role in Satellite Communications

Strategic Influence in U.S. Aerospace and Satellite Sectors

Viasat holds a critical position in the U.S. space and satellite industry, playing both a commercial and strategic role in how digital services reach users across the globe. Headquartered in Carlsbad, California, the company integrates satellite design, production, launch, and operations into a single value chain—rare among satellite operators. This integrated structure allows Viasat to rapidly respond to governmental and commercial needs with a high degree of control over system requirements and deployments.

The company supports important national security demands while also delivering high-capacity communications to commercial users. From DoD-backed programs to in-flight broadband for major airlines, Viasat operates at the convergence point of defense technology and consumer telecommunications.

A Decade of Scaling: The Global Xpress Satellite Network

Launched originally by Inmarsat in 2013 and acquired by Viasat in 2023, the Global Xpress (GX) network is the first and only globally available mobile broadband satellite network managed on a single operator-owned platform. Since its inception, GX has scaled through a series of payload launches—GX1 through GX5—each expanding coverage and bandwidth incrementally.

This continuous evolution transitioned the network from regional to full global coverage, integrating spot beam and steerable satellite technology to allocate bandwidth dynamically. With the GX10A and GX10B payloads, Viasat adds high-throughput spot beams to provide consistent broadband performance in high-latitude regions, breaking through previous polar limitations.

Multi-Sector Capabilities in Space-Based Connectivity

Viasat delivers broadband satellite services across a diverse set of markets. This includes:

These multi-domain services position Viasat as a cornerstone in both national defense and commercial innovations. With new expansions like the GX10 satellites, that role only deepens.

Decoding the GX10 Satellite Expansion

What are the GX10 Inmarsat Satellites?

The GX10A and GX10B satellites are dual-payload geostationary communications satellites developed by Inmarsat, now part of Viasat. Built by Northrop Grumman using the GEOStar-3 platform, each satellite carries a high-capacity Ka-band payload. The mission: deliver uninterrupted broadband coverage across high-latitude regions, specifically targeting areas above 65 degrees north and below 65 degrees south latitude.

Scheduled for launch aboard SpaceX Falcon 9 rockets, GX10A and GX10B will host steerable spot beams and fixed wide beams. This configuration ensures precise coverage over both the Arctic Ocean and Antarctic landmass—regions traditionally underserved by geostationary satellites due to their extreme positions on the globe.

Integration into the Viasat Global Xpress Network

GX10A and GX10B will integrate directly into Viasat's Global Xpress (GX) network, a worldwide Ka-band satellite network originally deployed by Inmarsat. The GX network includes I-5 and I-6 satellites stationed in equatorial geostationary orbits, delivering mobile broadband services to aviation, maritime, government, and enterprise customers.

The GX10 expansion leverages the same ground infrastructure, terminal compatibility, and service architecture. This plug-and-play approach enables existing GX users to access extended coverage in polar zones without hardware modifications or bandwidth realignments.

Enhancing Connectivity at the Poles

Why focus on polar regions? Because traditional geostationary satellites orbit above the equator, creating coverage gaps near the poles where satellite elevation angles drop below usable thresholds. With GX10 satellites positioned in highly inclined elliptical orbits—technically Tundra class GEO orbits—they maximize dwell time over the Arctic and Antarctic.

This orbital design ensures high-throughput, low-latency Ka-band coverage where previously only low Earth orbit (LEO) constellations could reach. By closing the polar gap in its geostationary network, Viasat enables year-round, next-generation broadband for scientific stations, maritime fleets on trans-Arctic routes, and emerging Arctic infrastructure projects.

With this expansion, Viasat redefines satellite reach—not by reimagining what satellites can do, but by changing where they do it.

Why Polar Region Connectivity Matters

Reliable Communication in High-Latitude Zones Fuels Modern Operations

Expeditions, scientific missions, defense patrols, and commercial shipping routes all operate in the polar regions with increasing frequency, yet these remote areas remain some of the least connected on Earth. Traditional satellite constellations struggle to maintain consistent coverage at latitudes above 65 degrees North or South due to geometry and orbital limitations. The demand for uninterrupted, high-bandwidth communication continues to grow, driven by military units, researchers, maritime operators, and energy companies operating in the Arctic and Antarctic zones.

As shipping routes like the Northern Sea Route open up due to melting ice, vessels and convoys require real-time navigation data, dynamic weather updates, and emergency communication. Without reliable connectivity, that data flow cuts off, delaying operations or risking lives. Enhanced polar coverage from new high-throughput satellites solves this visibility gap.

Strategic Importance of the Arctic Across Government, Science, and Industry

Military forces monitor the polar regions for national defense, missile detection, and surveillance as part of their broader Arctic strategy. For example, the United States, Canada, Russia, and China have all expanded Arctic operations and infrastructure over the past decade. Arctic Council member states are actively reinforcing communication networks to ensure domain awareness and operational readiness in sub-zero conditions.

For the scientific community, polar regions are core to understanding climate change. The Arctic warms nearly four times faster than the global average, a pattern revealed by data-intensive climate models, field measurements, and glacier monitoring stations. These research sites transmit terabytes of sensor data from high-latitude installations. Every gap in connectivity can slow down high-resolution climate modeling.

In addition, the energy sector, particularly offshore drilling and natural gas exploration firms, count on secure satellite uplinks to maintain operational control in the polar frontier. From realtime telemetry to pipeline monitoring systems, their infrastructure often sits outside traditional coverage zones—and demands fault-free connectivity.

Geopolitical and Commercial Stakes Are Rising

Competition for sovereignty, resources, and access routes is growing sharper in the polar territories. Russia's deployment of icebreakers and investment in northern military bases, coupled with new Chinese investment in Arctic research and shipping hubs, reframe the polar regions as new centers of economic and geopolitical gravity.

At the same time, commercial interest is attracting investment from logistics firms, renewable energy developers, and aerospace companies. The search for new maritime trade paths and untapped natural resources shifts corporate strategy northward. As a result, connectivity becomes an operational prerequisite—not just a convenience.

Every one of these initiatives relies on robust, high-speed communication. Expansion of polar connectivity on Viasat’s GX10 eliminates critical blind spots and enables these strategic pursuits.

Engineering Polar Reach: Technological Breakthroughs from Viasat in GX10 Expansion

Satellite Integration for Coverage that Withstands Extremes

The GX10 satellite expansion marks a turning point in orbital architecture through the strategic integration of Low Earth Orbit (LEO) and Geostationary (GEO) satellite layers. Instead of relying solely on the fixed coverage of GEO satellites, which orbit at approximately 35,786 kilometers, Viasat now weaves in the agility of LEO systems positioned between 500 and 2,000 kilometers above Earth. This hybrid structure achieves two key objectives: persistent polar coverage and system redundancy.

When one layer encounters latency or atmospheric disruption, the alternate layer dynamically compensates. Communication routes aren't blocked—they reroute. The result: enhanced resilience against geomagnetic storms, fluctuating ionospheric conditions, and rapidly changing polar weather systems. This fusion of orbital layers means data travels faster, further, and more reliably—even at 90 degrees latitude.

Transmission Technology that Withstands -50°C Temperatures

Designing antennas and transceivers for the Arctic and Antarctic requires more than just durability. Sub-zero conditions, high winds, and ice accumulation pose direct threats to uplinks. Viasat’s solution: phased-array antennas with electronically steerable beams and integrated de-icing systems. These arrays, which don’t rely on mechanical motion, operate continuously in wind speeds exceeding 120 kilometers per hour and persist through temperatures plunging below -50°C.

Beam agility allows the system to target fast-moving LEO satellites while maintaining a secure handshake with GEO units. Combined with adaptive modulation techniques and forward error correction protocols, these technologies preserve signal integrity and maximize throughput. Where bandwidth typically collapses under icy stress, Viasat’s hardware processes uncompromised Ka-band transmissions up to 10 Gbps in bandwidth per payload beam.

Infrastructure Expansion: From Orbital Nodes to Ground Control

Viasat’s efforts extend beyond superior satellite payloads. Robust polar connectivity depends on a triangulated architecture—space assets, ground stations, and cloud-enabled service layers. The company has installed multi-band gateway earth stations in strategic sub-Arctic locations such as Svalbard and Northern Canada, reducing latency and improving data backhaul precision.

These ground stations utilize secure laser interconnects to transfer terabits of data per day across fiber networks linked to North American and European data centers. In orbit, autonomous resource management software allocates satellite bandwidth, considering atmospheric data and user traffic patterns in real time. This unifies the system into a single-functioning entity engineered to thrive at Earth’s most challenging edges.

How do these advancements translate for operators, governments, and researchers working in polar zones? Connectivity isn't just available—it performs, scales, and endures.

Unprecedented Strategic Gains for U.S. and Global Stakeholders

Broadband for Oil Rigs, Mining Facilities, and Ocean Fleets

Operating in the Arctic has always posed hard limitations due to the sheer isolation and lack of communication infrastructure. The GX10 payloads on the Arctic Satellite Broadband Mission (ASBM), hosted on satellites operated in partnership with Space Norway and the Norwegian Ministry of Defense, enable Ka-band coverage above 65° North latitude for the first time on a commercial network. That’s a coverage zone spanning the entire Arctic Circle.

Advancing Polar Aviation with Real-Time Data Exchange

Commercial and cargo flights transiting polar airspace often face challenging conditions compounded by patchy connectivity. The GX10 constellation brings seamless Ka-band access which enables continuous cockpit communications, flight tracking, and inflight broadband from gate to gate—even at latitudes above 75° North.

Flights from Asia to North America and Europe that cross the pole involved unavoidable hand-off zones without broadband service—those gaps no longer exist with GX10A in orbit. Airlines, air traffic control, and passengers all benefit from consistent data flow, raising both safety and service standards.

Eliminating Blackouts, Elevating Efficiency

Previously, polar operators were limited to solutions like low-data-rate Iridium systems or expensive, intermittent leased-bandwidth networks. GX10 redefines the baseline. It reduces latency, increases bandwidth availability, and integrates polar coverage into the global network footprint of Viasat, enabling a uniform communication standard across every latitude.

Site managers can implement cloud-based software platforms, real-time logistics planning, AI-based remote sensing tools, and video conferencing without delay or degradation. That isn’t just a luxury—it’s a force multiplier for crew safety, operational sustainability, and logistical control in inaccessible regions.
