A method for determining the Earth’s magnetic field components on a moving object having its own magnetic field is presented. A simplified scheme is considered to illustrate the method of problem solution. Equations yielding a correct solution for both the simplified scheme and a real moving ferromagnetic object are derived. Technological problems are listed that can be solved by measuring the Earth’s and other magnetic fields onboard a moving object with an arbitrary magnetic field of its own.
