On integration of a strapdown inertial navigation system with modern magnetic sensors

In this paper, we consider algorithms of integration of strapdown navigation systems with measurements of the geomagnetic field. We present numerical results for these algorithms, obtained with the help of geophysical survey data and characteristics of inertial and magnetic sensors from datasheets. We analyze high-grade navigation systems as well as low-grade ones. In conclusion, we present a table with performance results for all considered variants of integrated navigation systems.
