High, Very-High And Extremely High Throughput Satellites
Multi-Orbit / Multi-Band Network Architectures
December 11th . 2025 . 14:00 UK Time (GMT) . 15:00 (CET) . 09:00 (EST)
Held Bi-Annually in London and Washington DC as a person to person event since 2012... this programme has advanced with the continuously evolving contours of the satellite industry, from the hugely powerful FSS satellites launched shortly after the turn of the decade, through to the current era of multi-sized, multi earth orbit, mega-constellations of communications satellites and their supporting frameworks. Ongoing demand for satellite–telecom integration and multi-orbit connectivity suggests a future where GEO, MEO and LEO satellites operate alongside each other in blended scenarios, to deliver stronger, more reliable networks to an expanding base of industrial and consumer applications.
The HTS programme has featured speakers from Satellite Operators, Service Providers and Equipment Designers, as well as representatives from the industries that they serve.

GEO Vs Non-GEO HTS - Market Opportunity and Multi-Orbit Strategies
Prachi Kawade, Senior Analyst
Synopsis:
The surge in HTS and VHTS capacity, alongside disruptive LEO players like Starlink and Amazon LEO, is redefining satellite connectivity economics, reshaping pricing models and service expectations. This session examines demand shifts across GEO and Non-GEO orbits and outlines strategic roadmap for legacy operators, including multi-orbit integration, to secure long-term competitiveness.

Beyond the Earth's Core: Optical Core Networks in Space
Kevin Shortt, Research Project Leader, Optical Communications
Synopsis:
Today's low Earth orbit constellations are being built upon a foundation of free-space optical communication technologies that are changing the nature of satellite communications. Unlike satellite services of the past, optical inter-satellite links (ISL) provide the capacity to carry the full range of services carried by terrestrial fiber networks. While optical ISLs have a storied history of successful operations over the last 20 years, their use has been relegated to the kinds of services more akin to access networks. To unlock their full potential requires a shift in thinking towards deploying optical core networks in space.

Multi-network Multi-orbit products: how to make the best use of each individual underlay network to deliver a step change in customer quality of experience?
Jerome Soumagne, Vice President Systems Engineering
Synopsis:
Each network (satellite (Viasat GEO, 3rd party NGSO) or terrestrial (5G)V) has certain technical, regulatory and commercial attributes. There is not a single network that ticks all the boxes. We will discuss ways to aggregate/bond these networks in order to deliver the best value to customers.

Applying AI and Digital Twin Techniques to Multi-Orbit NTN Network Optimisation
Manish Shrivastava, Senior AIOps Strategy and Solutions Advisor
Synopsis:
A focus on practical use cases from LEO/GEO multi-orbit deployments – capacity planning, traffic steering, QoE-driven optimisation, and operations automation – and a view to where the industry is heading with 5G/6G + NTN convergence. Also, key challenges of multi-orbit (GEO/MEO/LEO) and multi-band networks—dynamic traffic, weather and interference, handover and QoE and how AI plus a network digital twin can be used as a “safe sandbox” to model these effects, test optimisation policies and automate actions across planning, assurance and operations.

New Multi-Orbit Partnership Model: Riches in Niches with Partners and the Chief Satellite Officer
Ahmet Eren, Senior Sales Director MENA and Central Asia
Synopsis:
The satellite connectivity sector is at a strategic inflection point. The explosion of capacity from VHTS and LEO players are rapidly redefining network economics and service expectations. Serving high-value, specific customer requirements—the "Riches in Niches"—by effectively leveraging the unique strengths of multi-orbit (GEO,LEO) and multi-network (Satellite, 5G/6G NTN) capabilities is crucial. This session offers a look at a GTM strategy for a GEO/LEO satellite operator working with partners and dedicated Chief Satellite Officers.

It’s Not “One Orbit Fits All”
Diego Paldao, Director S&BD Enterprise & Cloud
NB:
Since this recording, Diego has taken the position of Senior Director of Global Sales and Business Development with Volta Space, which aims to build the lunar energy grid, enabled by optical power beamed from satellites in lunar orbit.
Synopsis:
This presentation aims to highlight the importance of well-fit satellite solutions, emphasizing that no single orbit can address all customer challenges. By exploring GEO HTS and next-generation MEO capabilities, as well as access to low Earth orbit (LEO) solutions through strategic partnerships, we will demonstrate how different or combined orbits can be leveraged to solve specific requirements effectively. The session includes case studies showcasing the practical applications and benefits of SES’s multi-orbit capabilities. Attendees will gain insights into matching the right satellite solutions with their unique needs, ensuring optimal performance and results.
