The existing geomagnetic matching technique demands information from the inertial navigation system (INS). In order to reduce the cost of the navigation system, a novel matching method with both the magnetometer and milemeter is presented. To search the path in the huge space, the genetic algorithm is employed. Correlation measure is used as the fitness function and the random variation is superseded by oriented variation. Simulation results show that this approach can be used for effective matching in different forms of path with enough positioning accuracy.

Key words: geomagnetic matching navigation, genetic algorithms, correlation methods, oriented variation, search strategy
