The HTS Roundtable

High and Very High Throughput Satellite Systems: GEOs . MEOs . LEOs

December 7th . 2023 . 14:00 UK Time (GMT)

Held Bi-Annually in London and Washington DC as a person to person event since 2012... the HTS Roundtable has evolved, with 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 hyperconvergence with terrestrial technologies, initially to meet the demands and requirements of remote connectivity scenarios but more recently, to enhance the capability of terrestrial networks to cope with exponentially rising data volumes, not just in remote locations but urban settings too.  The HTS Roundtable has featured speakers from all of the Satellite Operators, Service Providers and Equipment Designers.

Gareth Hartwell, Director Of Consulting Services, Defence, Space, and Intelligence

  • High Throughput LEO Constellations + Terrestrial.. How to Provide Rail Connectivity, even in the Most Challenging Conditions? (Pdf.Slides) (Mp4.Recording)

Synopsis: Based on the CGI experience from recent trials on the North York Moors... This presentation will describe the challenge train operators have in providing connectivity for passengers and train crews and how new generations of LEO satellites like OneWeb can be used. This presentation will also describe how a solution trialled in October, in extremely challenging conditions, with 60% terrestrial connectivity, obtained some very good results.

Gareth is leading programmes related to the application of satellite communications within the rail and aviation sectors including the recent trial of LEO satellite services to provide seamless passenger Wifi on the remote North York Moors Railway. CGI is among the largest IT and business consulting services firms in the world... active in 21 industries across 400 locations worldwide, providing Business consulting, Systems integration, Intellectual Property, Managed IT, Business process services, Digital transformation, and emerging technology.


15.05    Ramon.Space

Steve Good, Chief Business Officer

  • Re-defining HTS (Pdf.Slides)

Synopsis: With the advent of power-efficient earth-like computing solutions in space, the term High Throughput Satellite is going through a redefinition as new intelligent innovations will be implemented to truly change the allocation of resources on-the-fly and ensure maximum throughputs are achieved. Additionally, gone are the days of set-it-and-forget-it satellites as spacecraft can now be reprogrammed and truly “learn on the job”, pushing High Throughput to levels unseen in the past.

Steve is the Chief Business Officer with Ramon.Space having spent three decades working in the satellite industry with Comtech EF Data, Hughes Network Systems, Intelsat, Verestar and Thales Alenia Space. Ramon.Space is committed to making the final frontier possible by bringing Earth-like computing infrastructure to Space. The company equips satellites with storage, processing and connectivity capabilities to enable the next generation of space applications and services.


15.25    Calian Advanced Technologies

Russ Palmer, Vice President Software Solutions

Synopsis: As software-defined satellites offer the industry unprecedented increases in bandwidth and flexibility, they also introduce more complexity in coordinating changes between the satellites and the ground segment. Calian’s resource management and orchestration solutions empower the operations between space and ground by seamlessly facilitating the interaction and adaptability between the satellites and the ground segment.

Russ is responsible for Software Defined Solutions within Calian Advanced Technologies’ Space division. Russ and his team design and deliver innovative and advanced systems for satellite communications and earth observations. Calian is a global supplier of highly technical solutions, services and products to, among others, the satellite industry... working with key clients including Canadian Department of National Defence, Inmarsat, Intelsat, European Space Agency, Space Systems Loral, Boeing, Hughes, Lockheed Martin, Sirius XM Satellite Radio and Cobham SATCOM.
