Technical Committee (TC) Satellite Earth Stations and Systems (SES) Activity Report 2019

Chair: 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.

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 2019 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.

These standards variously cover Mobile Earth Stations (MES); Receive-Only Mobile Earth Stations (ROMES); Aircraft Earth Stations (AESs); fixed and in-motion Earth Stations communicating with non-geostationary satellite systems (NEST); Land Mobile satellite Earth Stations (LMES); Maritime Mobile satellite Earth Stations (MMES); Earth Stations on Mobile Platforms (ESOMP); Satellite Earth Stations on board Vessels (ESVs); Vehicle-Mounted Earth Stations (VMES); Tracking Earth Stations on Trains (ESTs); and Very Small Aperture Terminal (VSAT) satellite earth stations.

During the year work continued (mainly in our SCN Working Group) on a Harmonised Standard covering GNSS. This WG also completed work on a new Technical Report that considers seamless integration of satellite and/or HAPS (High Altitude Platform Station) systems into 5G and related architecture options. Meanwhile our HARM Working Group progressed development of a standard for fixed earth stations operating over non-geostationary (NGSO) satellites in the Ka-band.

In parallel, further progress was made on revising the technical specifications for performance requirements and test specification for the GNSS based Location system.
