    • Sealink Multi-LEO connectivity

    One data allowance. One subscription. Fully managed. Built for maritime.

    A single, vessel-specific data allowance delivered across multiple low Earth orbit satellite networks through one fully managed Marlink solution.

    Marlink is the only maritime connectivity provider to deliver one data allowance operating seamlessly across Starlink and Eutelsat OneWeb under a single monthly subscription - with no split allowances, no multiple contracts and no operational complexity.

    Powered by the Marlink possibility platform and enabled through XChange NextGen, Multi-LEO becomes more than connectivity, it becomes an enabler of resilient operations, consistent digital performance and fleet-wide standardisation.

    What makes Sealink Multi-LEO different

    One data allowance, delivered across multiple LEO networks

    Competitors offer parallel LEO services that must be managed seperatly
     Marlink delivers a single, vessel-specific data allowance that operates seamlessly across Starlink and Eutelsat OneWeb - with predictable costs and no manual switching, while giving high availability on High Throughput service.

    Optional fleet pooling capability

    Where fleet operations require it, Marlink can enable fleet-level pooling options, allowing vessels within the same fleet to share allowances across multiple LEO networks - all within a single managed service model.

    Carrier-agnostic by design 

    Marlink is not tied to a single constellation.
    We select, blend and manage connectivity based on performance, availability and operational need - not commercial lock-in. This ensures vessels always benefit from the most suitable network for their operating conditions.

    Fully managed, end to end

    From network design and integration to monitoring, optimisation and lifecycle management, Marlink operates Multi-LEO as a service - not as a collection of terminals, providers or contracts.

    Built into a broader digital ecosystem

    Multi-LEO is fully integrated into the Marlink Possibility Platform, enabling security, policy control, visibility and orchestration across Connectivity, Cyber Security, Cloud & IT, and Applications.

    What is Sealink Multi-LEO?

    Multi-LEO connectivity for maritime operations

    Sealink Multi-LEO combines multiple low Earth orbit satellite services into a single, fully managed connectivity solution, purpose-built for the realities of maritime operations.

    By integrating leading LEO networks such as Starlink and Eutelsat OneWeb - individually or together — and blending them with GEO (VSAT Ku or Ka), MEO and 4G/5G where available, Marlink delivers fast, resilient and operationally consistent service continuity across global routes, also in areas where LEO services are restricted.

    All services are delivered through one service model, giving vessel operators the performance benefits of LEO without the complexity of managing multiple providers.

    Why Multi-LEO matters at sea

    → Improve resilience and uptime

    Satellite constellations perform differently depending on route, region, and traffic conditions. Each has distinct strengths and limitations related to coverage, congestion, latency, blockage, and licensing and geopolitical situations.

    Sealink’s Multi-LEO approach is designed to maintain high availability of low-latency, high-bandwidth connectivity across changing conditions - helping ensure critical services remain available when they are needed most and your crew stay connected. 

    → Secured by design

    Sealink Multi-LEO provides a highly secure connectivity solution by combining resilient multi-orbit satellite access with Marlink’s integrated cyber security services. Traffic is protected end to end through managed firewalls, secure gateways, continuous monitoring, and threat detection, ensuring that customer networks remain isolated from cyber threats even when switching dynamically between LEO constellations. By embedding cyber security directly into the connectivity service, Marlink delivers a robust, always-on solution that safeguards data, applications, and operations while maintaining high performance and availability for mission-critical maritime and remote communications.

    → Optimise digital performance

    Support crew welfare and business-critical applications with connectivity aligned to operational priorities - delivering the right balance of speed, latency, reliability and service assurance.

    → Simplify fleet operations

    One partner. One service model.

    Marlink brings design, integration, monitoring, support and lifecycle management together, delivering a consistent, scalable experience across vessels and fleets.

    Hybrid connectivity solutions with multiple networks

    As a connectivity-agnostic provider, Marlink enables vessels to combine LEO services with GEO VSAT and L-band connectivity (including Inmarsat, Iridium and Thuraya) within a single managed solution.

    Marlink delivers flexible and customizable managed hybrid connectivity, integrating LEO bearers with GEO VSAT services within the Marlink Possibility Platform.

    Our experts design, integrate and operate each solution to meet operational needs and budget, while ensuring secure, reliable communications.

    Stand-alone data packages (per network)

    For specific operational or contractual requirements, Marlink also offers dedicated data packages on Starlink and/or Eutelsat OneWeb, aligned to vessel profile, route patterns and onboard usage.

    Our experts design, integrate and operate each solution to meet operational needs and budget, while ensuring secure, reliable communications.

    Sealink NextGen managed solutions

    With Sealink NextGen, Marlink uniquely offers a single, vessel-specific data allowance delivered across Starlink and Eutelsat OneWeb under one fixed monthly subscription, fully managed by Marlink Possibility Platform.

    When combined with resilient, secured and global GEO VSAT Ku or Ka network, and / or L-band connectivity, it ensures worldwide high throughput service continuity and helps to prevent any penalties from authorities for potentially using non authorised service onboard.

    By combining the strengths of each connectivity type, Sealink NextGen provides high-speed, secure and resilient communications, delivering peace of mind across all operational scenarios.

    These solutions provide predictable costs and the flexibility to operate across either LEO and GEO constellation as required — with no split allowances, no multiple data pools and no manual switching.
