ITU-R WP 4C

International Telecommunication Union - Radiocommunication sector (ITU-R)

Study Group 4 (SG 4) - Satellite services

Working Party 4C (WP 4C)

Efficient orbit/spectrum utilization for the mobile-satellite service (MSS) and the radiodetermination-satellite service (RDSS)*

* WP 4C will also deal with the performance issues related to RDSS

Studies conducted within Working Party 4C are aiming at a more efficient use of the orbit/spectrum resources by MSS and RDSS systems. This includes analyzing various interference situations between such systems but also with systems operating in other radiocommunication services, developing coordination methodologies, describing the potential use of MSS and RDSS systems for specific purposes like emergency situations, maritime or aeronautical telecommunications, time distribution, etc.
