How Satellite Internet Works at Sea

Satellite internet keeps vessels connected globally by using radio signals relayed through orbiting satellites. Here’s how it works: when a ship sends data, it travels from the vessel’s antenna to a satellite in space, which then relays it down to a ground station tied to the internet backbone. For incoming data, the process is reversed.

This system relies on three main components: the satellite constellation itself, ground stations (also known as teleports) that link to terrestrial networks, and the onboard equipment on the vessel. These elements are strategically positioned worldwide to provide consistent coverage and backup systems.

Maritime satellite internet operates on specific frequency bands such as C-band and Ku-band, with newer systems increasingly adopting Ka-band for higher data speeds. Each band has its own strengths, including differences in signal strength, resistance to weather, and bandwidth. These factors play a crucial role in how satellite orbit types influence overall performance.

LEO vs. Geostationary Satellites

Geostationary satellites are positioned roughly 22,236 miles above the Earth’s equator. They remain fixed relative to the planet, allowing vessels to use simpler, stationary antennas. However, the distance introduces a delay: signals take about 500–600 milliseconds for a round trip, which can impact real-time communications.

In terms of performance, traditional geostationary systems provide download speeds ranging from 1 to 50 Mbps, depending on the user’s service plan and network traffic. Upload speeds are typically slower, between 256 Kbps and 5 Mbps. Despite the latency, these systems are known for their widespread coverage and decades of reliability across vast ocean areas.

Low Earth Orbit (LEO) satellites, on the other hand, operate much closer to Earth, at altitudes between 300 and 1,200 miles. This proximity reduces latency to just 20–40 milliseconds, making them ideal for real-time applications. LEO constellations require hundreds or even thousands of satellites to ensure continuous coverage, as each satellite moves quickly across the sky.

LEO systems can achieve download speeds exceeding 100 Mbps, with upload speeds often matching or nearing the same levels. However, they come with added complexity: shipboard antennas must track the rapidly moving satellites and seamlessly switch connections as satellites pass. This requires advanced – and more costly – tracking equipment.

Weather impacts the two systems differently. Geostationary satellites, particularly those using Ku-band frequencies, can experience rain fade during heavy storms, which temporarily reduces signal quality. LEO systems may show better resilience to weather, but this depends on the specific constellation and frequency band being used.

Required Hardware and Installation

For maritime satellite internet to perform well in ever-changing conditions at sea, the right hardware is essential. The most noticeable component is the satellite antenna, which plays a critical role in maintaining connectivity. Geostationary systems typically use parabolic dishes ranging from 24 inches to 8 feet in diameter. Larger dishes generally provide stronger signals and higher data rates. These antennas are housed within protective radomes to shield them from harsh weather and reduce wind drag.

Modern geostationary antennas are equipped with gyro-stabilized systems that keep the antenna locked onto the satellite, even in rough seas. High-end systems can maintain a signal in waves as high as 15 feet, though extreme conditions may still affect performance.

LEO satellite systems, meanwhile, rely on phased array or mechanically steered antennas to track the fast-moving satellites. These antennas are typically smaller and flatter than traditional dishes, making them a good fit for smaller vessels or situations where space is limited.

Below deck, the setup includes a satellite modem, which handles the conversion of digital data into radio signals and vice versa. These modems are built to endure the tough marine environment, withstanding temperature swings, high humidity, and constant vibration. Most setups also include redundancy features and automatic failover systems to maintain connectivity in case of equipment issues.

Proper installation is key to ensuring reliable performance. The antenna must be placed in a location with an unobstructed line-of-sight to the sky, away from interference caused by the ship’s structure, masts, or other equipment. Typically, this means mounting it at the vessel’s highest practical point. Professional installers use specialized tools to model signal coverage and pinpoint the best placement.

Power needs can vary widely. Smaller geostationary systems consume 50–150 watts, while high-throughput systems may require 300–500 watts. LEO terminals tend to use less power because of the stronger signals from closer satellites, though their advanced tracking mechanisms may offset this advantage.

Finally, the system’s cabling and internal networking tie everything together. Coaxial or fiber optic cables rated for marine environments connect the satellite equipment to the vessel’s internal network. Additional components, such as network switches and wireless access points, distribute the connection throughout the ship. Proper cable routing and weatherproofing are essential to prevent signal loss and protect equipment from damage caused by saltwater exposure.

How Cellular Internet Works at Sea

Cellular internet at sea functions by connecting to land-based cell towers through technology similar to what smartphones use. As ships move away from the shore, onboard systems communicate with coastal towers using radio waves, which are routed through terrestrial networks.

Unlike satellite-based systems, cellular maritime internet relies entirely on staying within range of land-based towers. A clear line of sight to these towers is essential for maintaining a connection. However, as vessels venture farther out, signal strength diminishes due to the Earth’s curvature and the limited range of coastal towers. Additional challenges, such as adverse weather and atmospheric interference, can further weaken the signal and affect reliability.

Modern maritime cellular systems often operate on 4G LTE networks, with 5G becoming more prevalent. These technologies provide faster speeds, lower latency, and better efficiency, making them ideal for operations close to the coastline. However, the reliance on land-based infrastructure means coverage is directly tied to how far a vessel is from shore.

Coastal Coverage Range

Ships generally experience reliable cellular coverage within 3–8 miles of the coast. LTE networks can extend up to 50 nautical miles under optimal conditions, while specialized equipment can boost the range to about 18–20 miles.

Several factors play a role in determining the actual coverage range. For example, the height of a ship’s antenna and the coastal terrain can significantly influence how far the signal travels.

Required Hardware for Cellular

Hardware is just as critical as signal reach when it comes to cellular internet at sea. Maritime cellular systems utilize durable equipment designed to handle harsh conditions like constant vibrations, temperature changes, and exposure to saltwater. Essential components include core routers, omnidirectional antennas, and signal boosters.

Marine antennas, typically omnidirectional, are mounted high on the ship to maintain a clear line of sight to coastal towers. Signal boosters are also employed to strengthen weaker signals, extending coverage where possible. The right combination of rugged hardware is key to ensuring stable and consistent internet access while navigating coastal waters.

Satellite vs Cellular: Direct Comparison

When deciding between satellite and cellular internet for maritime use, it’s essential to weigh their technical and operational differences. Coverage, speed, and cost are the key factors that will help you choose the right option for your vessel.

Coverage and Reliability

Coverage and reliability are where satellite and cellular internet diverge the most. Satellite internet provides global ocean coverage, making it accessible even in the most remote areas, as long as there’s an unobstructed view of the sky.

On the other hand, cellular internet excels in coastal waters. It offers reliable connectivity within 15–40 nautical miles of shore, but its performance drops off quickly as you move further out to sea.

Factor Satellite Cellular
Coverage Area Global ocean coverage Reliable within 15–40 nautical miles of shore
Weather Impact Can degrade during heavy rain or snow Minimal, though congestion may occur
Reliability Consistent with a clear sky view Strong within the coastal coverage range

Steve Gorman, Field Service Engineer at Super Yacht Americas Sales, KVH, highlights this advantage:

"With cellular, I think the biggest benefit right now is that with 5G, it can actually be faster than low earth orbit (LEO) services like Starlink and OneWeb." – Steve Gorman

Satellite internet performance varies based on the type of service. Traditional geostationary satellites often struggle with slower speeds and high latency, typically around 550 milliseconds. In contrast, LEO services like Starlink Maritime have transformed satellite internet, offering speeds between 5–250 Mbps and latency as low as 25–99 milliseconds.

Performance Metric Satellite (LEO) Cellular (4G/5G)
Download Speed 5–250 Mbps (varies by plan) 50 Mbps – 2 Gbps
Upload Speed 2–25 Mbps 8–80 Mbps
Latency 25–99 ms Under 64 ms (often single digits)
Performance Conditions Requires clear sky; weather-dependent Best within 15–40 nautical miles; may face congestion
