** (.):** Information capacity of the Earths magnetic field gradient parameters is analyzed in the context of solving the navigation problem with the correlation-extreme method. The navigation algorithms are suggested for the design with coupling of a magnetic-gradiometry-based correlation-extremal system and an inertial navigation system. Integration is supported by the solution of the inertial navigation correction problem, which is reduced to the standard form of a linear stochastic optimal estimation problem. This problem is solved with Kalman filtering and smoothing methods.
