The application of global and local harmonic models of navigational geophysical fields (NGPF) with high-order harmonics is substantiated. A series of advantages of such models over matrix (grid) NGPF models is examined. Harmonic mapping methods are examined. A no-search generalised Kalman filter algorithm of a harmonic correlationally-extremal navigational system (CENS) is given. Analytic estimates of the accuracy of a harmonic CENS in the en-route and terminal states are obtained for a simple correctable system.
