Abstract

In order to optimize the algorithm of geomagnetic/inertial integrated navigation, we establish platform of geomagnetic/inertial integrated navigation System, and study the geomagnetic matching location approach based on ICCP algorithm and MSD algorithm, data fusion based on Kalman filtering. The simulation system combines physical simulation with mathematical model. In the simulation the track-making software is used to generate the navigation data. The true navigation parameters of gyroscopes and accelerometers are superimposed with error data respectively, and then strap down inertial algorithm, geomagnetic matching and geomagnetic/inertial integrated navigation location are proceed. The simulation results indicate that the geomagnetic/inertial integrated navigation system has suppressed the error divergence of inertial navigation system and increase the pointing accuracy.
