SES Activity Report 2018-2019

Chairman: Jean-Jacques Bloch, Hughes Network Systems Ltd

Responsible for standardization relating to all types of satellite communication systems, services and applications including fixed, mobile and broadcasting; satellite navigation systems and services; 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.

Satellite technology is an important delivery platform for diverse services such as direct-to-home TV and mobile, high-speed Internet access and location services. It is particularly useful for rural and outlying regions, where it is difficult to deploy other systems on a commercial basis, and therefore plays a key role in ensuring that all European citizens are able to access high quality information services.

During 2018 our Satellite Earth Stations and Systems technical committee (TC SES) continued its work on the development and revision of Harmonised Standards for satellite earth station fixed terminals or terminals on the move, whether in an aircraft, on board a ship or in a vehicle. Throughout the year we actively pursued compliance of our Harmonized Standards with the Radio Equipment Directive (e.g. Global Navigation Satellite System Receivers).

We published a technical analysis on the radio frequency, modulation and coding for Telemetry Command and Ranging (TCR) of communications satellites.

During the year work progressed in other areas, including revisions to existing standards and specifications on performance and test specification requirements for GNSS location systems; radio spectrum access for indoor and outdoor satellite receivers; Mobile Earth Stations (MES) narrowband user equipment; Vehicle-Mounted Earth Stations (VMES) operating in the 14/12 GHz bands; Tracking Earth Stations operating in the 11/12/14 GHz bands; and Satellite Earth Stations on board vessels.

Work progressed on the integration scenarios of satellite in 5G and the associated architectures, as well as on the analysis of Protocol for Resource Management Interface. We also initiated new technical analysis on reference data models and on the configuration of satellite networks to support edge delivery in 5G systems.
