RESEARCH REPORT ON THE USE OF STARLINK SATELLITE INTERNET ON VESSELS AND COMPARISON WITH OTHER INTERNET CONNECTIVITY OPTIONS

1. Introduction

Within the contemporary maritime sphere, internet connectivity aboard vessels has evolved into a critical operational determinant, surpassing its previous status as a mere onboard amenity. The escalating integration of advanced applications and operational procedures necessitates high-throughput and stable internet connectivity to optimize operational efficiency, bolster maritime safety protocols, and enhance crew and passenger satisfaction, particularly within the cruise sector. Sophisticated fleet management systems, remote equipment monitoring capabilities, and the imperative for seamless ship-to-shore communication are all predicated upon robust internet infrastructure. The increasing reliance on real-time data for navigational and operational activities underscores the transition of internet connectivity from an optional feature to an indispensable operational requirement.

Among the array of internet connectivity solutions available for maritime applications, SpaceX’s Starlink broadband satellite service has emerged as a compelling alternative. Starlink utilizes a constellation of numerous Low Earth Orbit (LEO) satellites to deliver high-bandwidth, low-latency connectivity on a global scale. Concurrently, established connectivity solutions such as Inmarsat and Very Small Aperture Terminal (VSAT) systems remain integral to maritime communications. Inmarsat, a global mobile satellite communications provider, primarily leverages Geostationary Earth Orbit (GEO) satellites. Their service portfolio, including FleetBroadband and Fleet Xpress, provides a range of connectivity options tailored to maritime requirements. VSAT technology employs compact onboard antennas to establish communication links with satellites, typically GEO, facilitating internet access and other communication services.

A pivotal distinction between Starlink and traditional satellite communication systems resides in the operational orbital parameters. Starlink’s LEO satellites operate at a significantly lower altitude compared to the GEO satellites utilized by Inmarsat and VSAT. This disparity profoundly influences the latency and coverage characteristics of each respective system, resulting in distinct performance trade-offs. LEO satellites, by virtue of their proximity to Earth, inherently exhibit lower latency, a critical attribute for real-time applications such as videoconferencing and interactive online services. However, the achievement of continuous global coverage mandates a substantially larger satellite constellation relative to GEO systems. Conversely, GEO satellites, positioned at higher altitudes, offer broader geographic coverage with fewer satellites, albeit at the expense of increased signal propagation delay.

This report is commissioned to assess the viability of Starlink as an effective maritime internet connectivity solution, concurrently benchmarking it against established alternatives such as Inmarsat and VSAT across pivotal metrics including coverage, data throughput, latency, and cost. It will further scrutinize the respective advantages and disadvantages of each solution within the maritime domain, considering factors such as reliability under diverse meteorological conditions, hardware and installation requisites, and scalability. Ultimately, this report will synthesize the critical determinants for selecting an optimal internet solution for maritime vessels, culminating in a conclusive evaluation of Starlink’s efficacy and feasibility vis-à-vis competing options.

2. Starlink Satellite Internet for Maritime Vessels

Starlink extends satellite internet coverage across global oceanic and fluvial routes, encompassing international waters.
