Abstract. The work is devoted to a review of the current state of development of Russian and foreign integrated autonomous navigation systems, including GNSS satellite navigation equipment, an inertial navigation system (INS) and a meter for Earth’s magnetic field parameters (EMF). In such an integrated navigation system, when external conditions do not affect the operation of the GNSS, the classic “inertial system + satellite equipment” integration mode is used. In cases where satellite equipment is not capable of solving a navigation problem, correction based on the EMF is used to correct the INS.
A review of the literature shows that such autonomous navigation systems have been developed in Russia and abroad. They make it possible to achieve a location error of several tens of meters. Based on an analysis of the literature, the structure of an autonomous navigation system for the EMF is determined, and the plans of the Federal State Unitary Enterprise “VNIIFTRI” for creating such a system are presented.

Keywords: Earth’s magnetic field, autonomous navigation system, magnetometer.
