The Power of Multi-Orbit Satellite Networks
As the demand for reliable, high-speed global communications continues to grow, adding Non-Geostationary Satellite Orbit (NGSO) satellites to existing Geostationary Satellite Orbit (GSO) systems presents a game-changing opportunity. This multi-orbit approach enhances network performance, ensuring seamless, scalable, and resilient connectivity for consumers, businesses, and critical applications.
A key step toward realizing this vision is the strategic collaboration between Ligado and AST SpaceMobile to bring multi-orbit capabilities to the forefront in North America. By combining AST SpaceMobile’s advanced low-Earth-orbit satellite network with Ligado’s mobile broadband ready spectrum foundation, this collaboration aims to deliver a new layer of space-based mobile broadband connectivity across the United States and Canada. Delivered through domestic mobile network operators in each country, these services are designed to complement existing wireless networks, support carrier innovation and investment and preserve sovereign control of communications services within each country.
Why Add NGSO to GSO?
Traditional GSO satellites have long provided stable and widespread coverage, but they come with inherent limitations, including higher latency and bandwidth constraints in high-demand areas. NGSO satellites, particularly those in Low Earth Orbit (LEO), complement GSO systems by reducing latency, expanding coverage, and boosting network capacity.
By leveraging both systems together, satellite operators can deliver a superior communications experience that meets the evolving needs of modern society.
Key Benefits of Multi-Orbit Networks
NGSO satellites orbit much closer to Earth, significantly reducing the time it takes for signals to travel. This low-latency capability is crucial for applications such as video conferencing, telemedicine, financial transactions, and interactive gaming—where every millisecond counts.
While GSO satellites are highly effective for messaging, and IoT applications, their distance from Earth limits the bandwidth and link performance. NGSO satellites, operating in low Earth orbit and equipped with advanced high-gain antennas, can deliver significantly stronger signals and greater spectral efficiency, making standards-based mobile broadband services directly to smartphones possible.
NGSO satellites enable dynamic bandwidth allocation, ensuring high-speed performance even during peak demand. By offloading traffic from congested GSO networks, a hybrid approach optimizes service delivery, making satellite connectivity faster and more efficient.
A multi-orbit network reduces the risk of service interruptions caused by space weather, equipment failures, or interference. If a GSO satellite experiences downtime, NGSO satellites can provide immediate backup, ensuring seamless and continuous connectivity for critical applications.
A multi-orbit approach enables operators to deliver more flexible, high-performance connectivity while making the most of limited spectrum resources. By intelligently matching network capabilities with application needs, operators can optimize performance, cost, and capacity, maximizing spectral efficiency and improving overall service economics.
