The useful optimization function features for optimal choice of a plan linear induction machines structure.

Is examined the algorithm of the single-valued determination of objects coordinates from the results of phase shifts measurements at five metric frequencies of the radio-navigation system (RNS) "Krabik", intended for marine users navigation support. In this case single-valued coordinates realizes due to the use of a integer cycles search method of the phase ambiguity resolution and selection of a coordinates, which correspond to the maximum of a likelihood function. It is shown that the solution of the problem presented is achieved at the presence of redundancy in the system of equations, intended for determining the objects coordinates. The calculation the ambiguity resolution success rate, depending on a phase shifts root mean square error for "Krabik" RNS servicing zone is carried out.
