The evaluation of the feasibility of a digital device spatial orientation is made, built using a method of equivalent phase difference of the signals navigation system, operating under the Doppler Effect for a given accuracy of the determination of the spatial angle of object\'s rotation α and the maximal frequency of obtaining estimates of magnitude α.
Doppler frequency shift of the signals of navigation systems can be caused, for example, the maneuvering of unmanned aerial vehicles, change the current values of tilt angles of the object. In constructing the calculation algorithm may perform the procedure for finding the optimal baseline vector for which the Doppler shift frequency will be close to zero.
