Technical Committee (TC) Satellite Earth Stations and Systems (SES) Activity Report 2020

Chair: Jean-Jacques Bloch, Hughes Network Systems Ltd

Responsible for standardization relating to satellite communication systems, services and applications including fixed, mobile and broadcasting; satellite navigation systems and services. Covering all types of earth stations and earth station equipment, especially the radio frequency interfaces and network and/or user interfaces; and protocols implemented in earth stations and satellite systems.

The applications of satellite communications technology range from direct-to-home TV and mobile links to location services and high-speed Internet access, especially for rural and outlying regions or onboard aircraft and ships.

During 2020 our Satellite Earth Stations and Systems technical committee (TC SES) continued its work on the development and revision of Harmonised Standards covering all aspects of satellite earth station fixed terminals or terminals on the move, whether in an aircraft, on board a ship or in a vehicle. This notably includes:

  • Satellite communication systems, services and applications including fixed, mobile and broadcasting;
  • Satellite navigation systems and services;
  • Earth stations and earth station equipment, especially the radio frequency interfaces and network and/or user interfaces;
  • Protocols implemented in earth stations and satellite systems.

Throughout the year we actively pursued compliance of our Harmonised Standards with the Radio Equipment Directive as part of the ongoing consultation process with the EC. The committee’s work thus saw regular interaction with the HAS consultant on several ENs to receive comments on compliance with RED requirements, and addressing them to ensure our Harmonised Standards were better positioned to pass the ENAP procedure and achieve listing in the Official Journal of the EU.

We published a Technical Report [TR 103 611] on seamless integration of satellite and/or HAPS (High Altitude Platform Station) systems into 5G and related architecture options. This supports necessary standardization activities in relation to relevant satellite (communication and/or navigation) technologies.

We also revised our multi-part Technical Specification [TS 103 246] for GNSS based location systems, variously considering functional requirements [TS 103 246-1], reference architecture [TS 103 246-2], performance requirements [TS 103 246-3], requirements for location data exchange protocols [TS 103 246-4] and performance test specifications [TS 103 246-5].
