Starlink, Viasat & HughesNet: LEO vs GEO for Telco Growth
Telcos are witnessing a fundamental shift as two satellite architectures—Low Earth Orbit (LEO) and Geosynchronous Equatorial Orbit (GEO)—compete for dominance in future connectivity.
LEO constellations, epitomised by SpaceX’s Starlink, are rapidly eroding the market hold of established GEO providers such as Viasat and HughesNet. The competition is driving major innovation, with the LEO market projected to surge from US$11.8 billion in 2025 to US$20.6 billion by 2030.
The LEO proposition: Speed, agility and integration
LEO satellite systems, such as those operated by Starlink, are transforming delivery expectations in both consumer and enterprise markets.
By deploying thousands of satellites at altitudes up to 2,000 kilometres, LEO operators offer connections that closely resemble terrestrial broadband, achieving high speeds of 100 to 250 Mbps and low latency of 20 to 50 milliseconds.
Starlink’s expansion strategy leverages full vertical integration, utilising its parent company, SpaceX, for launches and marketing directly to end users, with straightforward, no-contract plans.
The model has made Starlink especially compelling for premium residential and enterprise segments seeking fibre-like quality, even if end users incur higher initial hardware costs.
Having secured a broad consumer base, Starlink’s focus is on enterprise, mobility and government markets, a testament to the flexibility and appeal of the LEO approach.
“LEO satellites provide true global coverage with low latency, typically more than five times faster than GEOs, making the user experience more akin to terrestrial fibre-connected devices.”
This dramatic reduction in lag enables LEO networks to support a diverse range of real-time applications, from video conferencing to online gaming and mission-critical public safety communications.
The GEO Response: Coverage, Economics and Reliability
GEO architecture, meanwhile, remains a staple of wide-area connectivity, using a small number of large satellites stationed 36,000 kilometres above the equator. It altitude allows each satellite to cover a vast footprint and deliver consistent service to static receivers.
Providers like Viasat maintain their competitive edge through lower initial costs, equipment leasing models, and market collaborations—for example, Viasat’s partnership with BSNL to launch consumer satellite internet in India.
As AST Networks notes:
“GEO’s architecture is uniquely valuable for applications like television broadcasting or weather forecasting where the end-user or ground system can be static, and continuous high-capacity regional coverage is needed.”
However, high latency—typically exceeding 500 milliseconds—renders GEO less suitable for latency-sensitive or mobile use cases.
Moreover, the production and launch of GEO satellites require longer lead times and larger capital investments, though these assets offer longer operational life and lower orbital congestion risk.
GEO’s robustness and simple ground infrastructure requirements ensure that terrestrial users need only point an antenna at the satellite to maintain a connection, a significant advantage for institutions prioritising stability over agility.
Technical and operational trade-offs
Technical analysts highlight significant engineering distinctions between LEO and GEO.
“Due to the distance from the planet, GEO satellites require a high-power directional antenna that must continually align towards the satellite, which may pose a challenge for assets in continual motion.
"These aircraft are better suited to LEO Satcom.”
The relatively lightweight and flexible nature of LEO terminals opens up new possibilities in the aviation, maritime and emergency response sectors, where agile, on-the-move connectivity is invaluable. LEO’s lower altitudes also mean lower power requirements and rapid network upgrade cycles.
Yet, the LEO approach comes with notable complexity. As Symmetry Electronics observes:
“While GEO satellites are bigger and more expensive to deploy, the network operator can gradually add to their coverage as their business grows.
"The downside with LEO satellites is that many are needed to cover any specific geographical area.
"This also adds to the network complexity as many ground stations are needed to communicate with all these satellites and they also need to use different frequencies to avoid interfering with each other’s communication.”
Operational models thus reflect a strategic trade-off: GEO’s simplicity and cost-effectiveness in static scenarios versus LEO’s ability to deliver low-latency broadband anywhere on the planet, albeit with more intricate ground and network management needs.
A changing market and hybrid models
With more than 80% of operational satellites now in LEO, the space environment is becoming more crowded, elevating the need for better traffic management and sustainability planning.
Industry executives now view the market as a contest between a “best possible” LEO network and a “good enough” GEO solution. Starlink’s LEO technology is increasingly favoured for users demanding high performance, while Viasat’s GEO offerings target cost-sensitive customers and basic connectivity requirements.
There is industry momentum behind developing hybrid, multi-orbit networks that combine the strengths of both architectures, aiming to deliver both extensive coverage and fibre-like performance.
Chris Quilty, CEO, Quilty Space summarises the pivot in perspective:
“It now appears that for many or most applications, a sufficiently scaled LEO constellation can provide better service across almost every attribute compared to GEO constellations.”
Informed choices for a competitive future
Telcos face crucial decisions as LEO and GEO architectures evolve. LEO excels in terms of latency, mobility, and service flexibility, particularly for applications that require real-time performance.
GEO maintains its importance for providing reliable, cost-effective coverage, especially where infrastructure stability and capacity are primary concerns.
As hybrid solutions emerge, telcos should closely align their satellite strategies with specific use cases, geographic reach, and customer expectations to remain competitive in a rapidly changing connectivity landscape.
