  • Method and device for the radioelectric synchronization of slave stations by a master station, especially for a microwave landing control system
    Patent number: 4757320
    Abstract: A method for the radioelectric synchronization of slave stations by a master station, especially for a MLS type landing control system. The method consists in transmitting by the azimuth station a synchronization data coded in the form of a series of short duration pulses, prior to each MLS cycle, a cycle being constituted by a plurality of successive transmission of MLS functions.

  • Process for increasing the range and particularly the protection against jamming of an MLS landing system and means for performing this process
    Patent number: 4617569
    Abstract: A process and means for increasing the range and the protection against jamming of a MLS system. It consists of transmitting a supplementary or reinforced preamble for each MLS function or group of MLS functions, via a scanning antenna used for the azimuth function, during the time when the latter is not normally used. This supplementary preamble consists of a certain number, e.g. four preferably accelerated scans, the variation between these scans being characteristic of the following function or functions.
