Determination of Phase Ambiguity in the Interferometer Using a Three-Frequency GLONASS Signal

The article describes the use of a three-frequency GLONASS signal to determine the phase ambiguity in the interferometer. The use of a three-frequency signal allows with high reliability to determine the phase ambiguity when using a sufficiently large distance between the antennas. In addition, it is possible to determine the phase ambiguity for each source of navigation signals separately.
