Аннотация: The article presents the results of experimental studies of the accuracy of measuring navigation parameters with a GNSS receiver equipped with an antenna array. The use of ring antenna arrays in GNSS receivers is substantiated. The main advantage of such antenna arrays is their invariance to the direction of the main lobe of the raПоказать полностьюdiation pattern in the azimuthal plane. The structure of the hardware-software complex for research is given and the principle of its operation is described. Its main parts are a 24-channel beam-forming GNSS receiver and an 8-element ring antenna array. The software and hardware complex allows the study of various configurations of antenna arrays - two, four and eight elements. The technique of carrying out the experiment is given. A feature of the technique is the use of differences in measured pseudoranges using a single antenna and various configurations of antenna arrays. The results of measurements of code and phase pseudorange are presented.
