METHOD FOR INTERFERENCE-PROTECTED RECEPTION OF SATELLITE COMMUNICATION SYSTEM SIGNALS Russian patent published in 2020 - IPC H04B7/185 

FIELD: satellite communication systems.

SUBSTANCE: invention relates to the field of satellite communication systems and can be used to receive signals of mobile satellite services of satellite communication systems (SCS) under conditions of deliberate or unintentional interference in the frequency range of both the communication system itself and global navigation satellite systems (GNSS), in particular, for receiving low-orbit SCS signals by user terminals of telecommunication systems located on mobile carriers. In the method for SCS signal-protected reception of signals of SCS and GNSS are provided by means of a multibeam antenna system. Carrier object angular position is determined based on separate or combined estimates based on phase shifts or RTK estimates of location by GNSS signals, after which based on data on spatial, including angular, position of carrier object, directivity patterns of antenna system are formed, designed to receive SCS signals each with maximum in direction of its SCS spacecraft with maximum towards its SCS spacecraft and dips in the direction of interference sources operating in SCS frequency range, current quality of SCS signals reception is estimated and, if necessary, adaptively redistribute antenna elements of antenna system for receiving GNSS and SCS signals.

EFFECT: technical result is a signal-interference environment-adaptive simultaneous noise-protected reception of SCS and GNSS signals based on spatial selection of interference, useful signals and determining the spatial orientation of the antenna system with the required accuracy and operability located on both the mobile and fixed carriers.
