METHOD AND DEVICE FOR THE SELECTIVE INTERFERENCE OF RECEIVERS, IN PARTICULAR OF SYSTEMS FOR SATELLITE-BASED POSITION DETERMINATION

摘要

The invention relates to a method and to a device that operates according to said method, that enables conventional (professional), in particular, GPS receivers (1, 1.1, 3, 3.3) to be selectively interfered with. According to the invention, the receivers (1, 1.1) that are not to be interfered with are equipped with means (2) that protect them from interferences (6) or with means (2) that enable the receivers (1, 1.1) to operate in specific time intervals (?t<SUB>2</SUB>, ?t<SUB>4</SUB>, ?t<SUB>6</SUB>). When the receivers (1, 1.1, 3, 3.3) are in operation, only the receivers (3, 3.3) that do not have any corresponding upstream means are interfered with so that said means can no longer display information on the location.
