AbstractObject of this present work is the application of multi-antenna systems to improve the noise immunity of satellite navigation systems for mobile objects. The aim of research is to develop noise-navigation system with multi-element antenna system for determining the angular position of a moving object in space. The paper discusses methods of construction and application of adaptive antenna systems for solving problems of interference suppression, as unintentional as well as custom designed.
Keywords:global satellite navigation systems, determining the angular position of a moving object, dynamic range, noise, receiver, antenna pattern, adaptive antenna, frequency band, digital control, adaptive filtering.
