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 Galileo PRS users. A political agreement on the cooperation nece ...[+++]ssary between the two radionavigation systems is required in preparation for a crisis or in the event of a crisis.

- The overlay of PRS frequencies and the discussions to be conducted on the subject between the European Community and the United States,

For the moment the United States is opposed to the overlay of one of the Galileo PRS signals with one of the GPS code M signals. It cites its defence policy priorities as its reason for wishing to retain the possibility of jamming the Galileo PRS signal.

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.

Whereas to this end, persons entitled to benefits for invalidity, old age and death (pensions) must be able to enjoy all the benefits which have accrued to them in the various Member States; whereas, however, in order to avoid unjustified overlapping of benefits, which could result in particular from the duplication of insurance periods and other periods treated as such, it is necessary to limit the benefits to the greatest amount which would have been due to a worker from one of these States if he had spent all his working life there;
