An adaptive algorithm for the ground and on-board equipment operation is developed for the use of satellite radio navigation systems using indirect antenna arrays, which increases the noise immunity of navigation equipment of consumers. To evaluate the efficiency of the algorithms, a full-scale experiment was conducted in an echo-free chamber. Comparative evaluation of quality of signals reception and estimation of navigation parameters errors determination under normal conditions and under conditions of intense interference, both when using the proposed algorithm and when using classical algorithms of signals processing used in adaptive antenna arrays of GNSS equipment is carried out. The proposed method shows operability and efficiency including with hybrid antennas.
