Ground-based navigation systems, despite the development of global navigation satellite systems, have not lost their relevance. Advantages of terrestrial navigation systems are their autonomy, high accuracy and noise immunity. However, ground-based navigation systems are used only to determine the current coordinates of the object, while in satellite navigation systems, phase methods for measuring the spatial orientation of the object have developed. To measure the spatial orientation, multi-antenna interferometers are used, the measured parameter is the phase shift of the carrier signal between the antennas of the interferometer. The main problem in measuring the spatial orientation is the resolution of phase ambiguity. Phase ambiguity is due to the fact that the length of the interferometer bases is usually several times the wavelength of the received signal.

The present work is devoted to the expansion of the functionality of terrestrial radio navigation systems by measuring the spatial orientation of objects.
