Phase interferometric methods are one of the most accurate methods for attitude determination of objects by the use of GNSS signals. In the presence of jamming interference, it is impossible to obtain phase measurements from spatially spaced antennas of the GNSS receiving equipment and this makes impossible to determine the attitude of objects using phase interferometric methods. In this article adaptive antenna arrays (AAA) are used for intentional interference suppression. A single-base interferometer based on two AAA is presented, and a new method for determining the angular orientation of the interferometer based on GNSS signals based on the method of reference phase differences is proposed. Results of modelling on the base of real signals records are presented showing operability of the new method in the presence of wideband interference. Statistical modelling is also carried out, showing the increase of interference immunity of the method of reference phase differences with using AAA by more than 40 dB.
