Arctic Operations Reveal a Communications Gap for US Military Forces

As melting Arctic ice opens new shipping lanes and increases military activity in the far north, a fundamental limitation in U.S. military communications is drawing new attention: many satellite systems used by American forces were never designed to provide reliable coverage near the poles.

Geography Limits the Reach of Key Military Satellites

Modern U.S. forces depend heavily on satellite communications to send command messages, coordinate operations, and transmit data across vast distances. Much of that connectivity relies on satellites placed in geosynchronous orbit, which are positioned roughly 22,000 miles above the Earth and rotate at the same speed as the planet. This allows them to appear fixed over a single point on the equator. This design allows antennas on ships, aircraft, and ground stations to maintain continuous links with a single satellite. 

However, satellites positioned above the equator cannot see every part of the globe. As users move farther north or south, the satellites appear lower on the horizon. At extreme latitudes, the curvature of the Earth blocks the signal entirely, creating areas where reliable communications become difficult or impossible.  

Jason Ferguson, chief executive officer of defense communications firm W5 Technologies, says that limitation creates a real challenge as naval forces operate deeper into Arctic waters.

“The way we do communications today is using geosynchronous satellites,” Ferguson said. “But those satellites rotate around the equator. When you move far enough north, the satellite simply can’t see you.”

Current Military Systems Were Not Designed for Polar Coverage

The U.S. military’s primary beyond-line-of-sight mobile communications network is the Mobile User Objective System, or MUOS. Developed for the U.S. Navy, MUOS enables voice, video, and data connections between forces operating around the world. 

The system provides guaranteed coverage between roughly 65 degrees north and 65 degrees south latitude, leaving the polar regions outside its assured service range. “Sixty-five degrees north is where the system has to work,” Ferguson explained. “Anything above that is not something you can depend on.”

That line runs through parts of Canada and Alaska. Areas farther north, including large portions of the Arctic Ocean, fall outside the guaranteed coverage zone.

The gap matters more today than when many of these satellite systems were first designed. Rising temperatures have reduced Arctic sea ice, opening new shipping routes and drawing growing commercial and military interest in the region. 

As traffic increases, naval forces and commercial vessels alike depend on reliable communications for coordination, safety, and situational awareness.

Limited Alternatives for Arctic Communications

Some commercial satellite networks can provide coverage in polar regions. Systems such as Iridium operate using constellations of low-Earth-orbit satellites that pass directly over the poles, allowing connectivity where equatorial satellites cannot reach.  

However, integrating these networks across military platforms takes time. Many ships and systems currently rely on communications equipment designed around existing military satellite architecture.

From Ferguson’s perspective, that leaves a capability gap. “There are solutions like Iridium or Starlink,” he said. “But those aren’t what are strapped into all the ships yet.”

When communications fail in polar regions, the effects are limited mainly to command and data links rather than navigation. Global Positioning System satellites operate in different orbital patterns that allow global coverage, meaning navigation services generally remain available.  

Still, losing communication links can complicate operations and limit coordination between units.

Different Orbital Approaches Offer Possible Solutions

Other nations have experimented with satellite designs better suited for northern regions. During the Cold War, the Soviet Union developed highly elliptical satellite paths known as Molniya orbits. These orbits allow satellites to spend long periods over high northern latitudes before moving quickly across the southern hemisphere. 

Such designs can significantly improve communications coverage in the Arctic. Yet they introduce different engineering challenges and costs compared with geosynchronous satellites.

Ferguson said W5 Technologies examined similar concepts while working on a Navy research effort exploring ways to extend military communications coverage into polar regions.

Rather than relying on specialized orbits, the company focused on placing existing communications capabilities onto platforms that could operate above Arctic users.

Putting Communications “Above the Soldier’s Head”

W5 Technologies develops wireless communications equipment for the defense market and has explored ways to adapt current military satellite systems to new platforms. 

One concept developed during research work involves packaging the capabilities of existing military communications systems into smaller payloads that could be carried on low-Earth-orbit satellites, unmanned aircraft, or high-altitude balloons.

The goal is to extend coverage into areas where geosynchronous satellites cannot reach while allowing military personnel to continue using existing radios.

“We’re trying to put the communication payload above the soldier’s head,” Ferguson said. “From their perspective, the radio just works.”

Because those payloads would replicate the behavior of existing systems, soldiers and sailors would not need to switch equipment or change procedures.

A Growing Issue as Arctic Activity Expands

The communications challenge does not necessarily create new vulnerabilities to electronic warfare. According to Ferguson, interference and jamming threats exist everywhere military communications operate, not just in the Arctic. Instead, the main issue is geographic.

Without additional infrastructure, forces operating far north may encounter situations where satellite connections become unreliable or unavailable.

“The capability our soldiers rely on isn’t there,” Ferguson said.

As Arctic routes expand and geopolitical interest in the region grows, addressing that gap may become increasingly important for both military planners and the companies building the next generation of communications systems.
