Приводятся результаты испытаний макетного образца СНС-гирокомпаса при искусственном создании искажений с помощью отражателя сигналов навигационных спутников.</p></abstract><trans-abstract xml:lang="en"><p>The paper focuses on the methods to reduce the satellite signal multipath effect on the accuracy of attitude parameters, in particular, the true heading, generated by the designed marine GNSS gyrocompass – INS/GNSS system with the single-axis rotation of the antenna and IMU units.
