At AST Networks, we are driven by the vision of connecting people and businesses wherever they operate, and the maritime industry is one of the most critical. As a leader in satellite communications, we have witnessed the challenges of traditional connectivity solutions and the potential of emerging technologies. We explore the transformative shift to Non-Geostationary Orbit (NGSO) satellites and their pivotal role in redefining maritime connectivity.
The Importance of Reliable Connectivity at Sea
For decades, the maritime industry has relied on satellite communications. Connectivity isn’t just a convenience, it is a critical part of modern maritime operations, enhancing:
• Safety: Access to real-time weather date, emergency alert, and navigational tools ensures vessels operate securely.
- Efficiency: Smart ship management depends on seamless data exchange for remote monitoring, route optimisation, and logistics coordination.
- Crew Welfare: High-speed internet improves quality of life onboard, enabling seafarers to stay connected with family and access entertainment.
- Passenger Experience: In the cruise sector, reliable internet is an expectation, essential for customer satisfaction.
For years, Geostationary Orbit (GEO) satellites were the primary enablers of maritime connectivity. However, their limitations are becoming increasingly apparent as the demands of modern operations outpace their capabilities.
Why GEO Can No Longer Keep Up
GEO satellites, 35,786 kilometres above Earth, provide wide coverage from a fixed position, but there is a cost:
- High Latency: The signal’s long travel distance leads to delays that hinder real-time applications like video conferencing or autonomous vessel operations.
- Polar Blind Spots: GEO satellites struggle to cover high-latitude regions, leaving critical Arctic and Antarctic shipping routes underserved.
- Bandwidth Bottlenecks: The growing need for high-speed, data-intensive services like streaming, telemedicine, and IoT stretches GEO satellites beyond their limits.
Its clear that maritime operations require a more advanced solution. This is where Non-Geostationary Orbit NGSO comes in.
How NGSO Satellites Transform Maritime Connectivity
NGSO satellites, operating in Low Earth Orbit (LEO) or Medium Earth Orbit (MEO), orbit at much lower altitudes (500-20,000 kilometres), and their benefits are game-changing:
- Ultra-Low Latency: With latency reduced to as low as 10-50 milliseconds, NGSO systems support real-time communications and applications. From remote diagnostics of critical equipment to virtual reality-based crew training, the possibilities are endless.
- Seamless Global Coverage: Unlike GEO satellites, NGSO constellations provide blanket coverage of the Earth, including polar regions. This is critical for fleets transversing the rapidly growing Arctic shipping lanes.
- High Bandwidth and Scalability: NGSO networks, such as SpaceX Starlink, OneWeb, and others, deliver high-speed broadband capable of meeting the demands of both operational systems and crew welfare. Dynamic bandwidth allocation ensures vessels in high-demand areas, like busy shipping lanes, maintain consistent performance.
- Built-In Redundancy: With constellations consisting of hundreds to thousands of satellites, NGSO networks provide robust redundancy. If one satellite is unavailable, another one in the constellation can seamlessly take over, ensuring uninterrupted connectivity.
Challenges and Opportunities in Adopting NGSO Technology
While NGSO satellites offer unparalleled advantages, their adaptation does require overcoming certain hurdles:
- Investment in New Infrastructure: Vessels need advanced terminals, like phased-array antenna, capable of tracking fast-moving NGSO satellites.
- Regulatory Compliance: Operating across multiple jurisdictions involves navigating complex frequency regulations and licensing requirements.
- Sustainability Concerns: The rapid deployment of NGSO constellations raises concerns about orbital congestion and debris management.
At AST Networks, we are committed to guiding our maritime partners through these challenges, ensuring seamless integration and compliance while maintaining our focus on environmental sustainability.
The Future of Maritime Connectivity
The integration of NGSO satellite constellations with complimentary technologies like 5G, edge computing, and AI will redefine what is possible in maritime operations. Autonomous vessels, augmented reality for remote repairs, and smart port interactions will rely heavily on the low-latency, high-capability connectivity provided by NGSO systems.
As we look to the future, AST Networks remains committed to enabling this revolution. Through our expertise and partnerships, we are driving the adoption of cutting-edge solutions that deliver unmatched performance and reliability for our maritime customers.
