Translation of "solid-state frequency modulator " (English → French) :

Since it is impossible to selectively jam a navigation signal using the same modulation and frequencies as another signal without seriously degrading it, allowing a full overlay with the same modulation of one of the two Galileo PRS signals with one of the two GPS M code signals means that the United States must reach an agreement with the Europe Community to ensure that its policy on any exports of PRS receivers is coordinated and compatible with theirs.

Until now, in its negotiations with the Americans, the Commission has put forward the scenario that the United States will not be able to jam one of the planned PRS signals because it will be overlaid on one of the future military GPS signals and it is not possible to selectively jam one of two signals overlaid on a single frequency band with the same modulation. As explained in point3.3 hereabove, the modulation used for the overlay would enable Galileo to transmit a much more "robust" and reliable signal. As a result, the United States would not be able to selectively jam G ...[+++]alileo PRS users. A political agreement on the cooperation necessary between the two radionavigation systems is required in preparation for a crisis or in the event of a crisis.

However, the United States, who until now enjoyed a de facto monopoly of satellite radionavigation, are currently - for strategic reasons - opposed to overlay of one of the two PRS signals and one of the two military (or code M) GPS signals at a specific modulation in the high frequency band.

WELCOMES the initialling of the Agreement between the European Community and the United States of America on the promotion, provision and use of GALILEO and GPS satellite-based navigation systems and related applications, NOTES with satisfaction the agreement reached recently on the issue of national security compatibility compliance requirements, together with a commitment from the United States, in the spirit of partnership upon which both sides have embarked, to find alternative PRS signal modulations if needed, and IS CONFIDENT that the Agreement which provides substantive benefits for both parties, can be signed in the near future, ...[+++]possibly at the EU-US summit on 26 June provided that the radio frequency compatibility document is finalised;
