Abstract:
Geomagnetic aided navigation is a new branch of integrated navigation technology, and the research on navigation error is an important part in analyzing the performance of inertial/geomagnetic integrated navigation system. This paper chooses the cruise aircraft flying at a constant or near constant height as its application object, establishes a Kalman filter for the inertial/geomagnetic integrated navigation system, and discusses the influences of each factor on the position and velocity errors by theoretical analysis and simulation results. These factors include revised method, accuracy of inertial sensors, geomagnetic feature, measurement error of magnetometer, grid interval of geomagnetic map, filtering period, and initial navigation errors.
