Priori geomagnetic information is important to the geomagnetic navigation. However in practice, the precision of the geomagnetic information is a greatly constraint to the development of the geomagnetic navigation. In order to solve this problem, this paper present a geomagnetic gradient bionic navigation method based on parallel approach without any priori information. Inspired by the evidence that many creatures can navigate using the Earth magnetic field, the navigation process can be considered as a convergence of multi-objective problem, and develop the bionics navigation model. By introducing the parallel approach method to the navigation process, the heading angle can be estimated with the information of magnetic field gradient. The simulation results show the proposed method is able to navigation effectively without magnetic priori information, just rely on the actual geomagnetic measurement, which has implies potential application in the future.

Simulation Results

For the case of the scheme trajectory command design for the tactical missile, the longitudinal and lateral commands and the compound controller of the attitude and height were designed. In the launch segment, four kinds of heading angle commands were presented adopting the arc method and reduction law. In the variable height flight segment, two kinds of height commands were gained by using the parabolic and exponential function. Considering the earth curvature, the formula of the great circle course and distance was gotten applying spherical triangle solution method, and the flight command along the route dot in the lateral plane was obtained. The simulation results show that the designed scheme trajectory commands are feasible and effectively.

Measurement method is studied utilizing vertical gyroscopevertical gyroscopevertical gyroscope, static earth magnetic field sensor and CPU. According to electromagnetism induction law, when a wire loop incises the magnetic force line of the earth magnetic field, it will bring about the induction electromotive force, the earth magnetic field can be calculated by signal processing of induced voltage in measuring coil. A heading and attitude measuring system to vehicle are designed, the heading precision were raised. Experiment data states clearly the heading precision is not more than 0.5°. This system can be used to detect heading and attitude, and can be extended easily.
