Measurement of the spatial orientation of objects using satellite navigation systems phase methods involves use of multi-base interferometer. In order to obtain measurements of angles with a high accuracy it is necessary to increase the distance between the antennas, leading to a problem of phase ambiguity resolution. One of the most effective methods of resolving phase ambiguity are the iterative methods. However their use imposes significant restrictions on the length of the base due to the large number of variants enumeration. In order to reduce them it can be used many methods to help narrow down your search. The article describes a method of resolving phase ambiguity using method minimizing the number of navigation satellites for the initial search and then checking obtained solutions for all navigation satellites.
