The project aims to perform the necessary studies to secure the allocation to BSS (Broadcasting Satellite Service) in the UHF band (620-790 MHz) in the ITU Radio Regulations.
On the regulatory side, the World Radio Conference (WRC-03) does not give a definitive conclusion on that subject as the studies conducted within ITU and the CEPT before the Conference were not finished and there were no clear conclusions to clarify the technical and regulatory situation in the 620-790 MHz band.
The main benefit of this project was to obtain from the 2003 World Radio Conference to continue the studies on that matter without accepting provisional pfd limits, which were not based on consistent studies.
The proposed system concept uses two different types of constellations to efficiently cover different part of the earth:

The purpose of the study was to participate and contribute to regulatory meetings in order to defend the BSS allocation.
A detail analysis of the interfering environment was first performed to confirm:
The study was kicked off on 26 March, 2003.
