Abstract

The perturbative effects of geomagnetic Lorentz force on the motion of a test object in orbit around the Earth are studied. A variety of orbital regimes: LEO, MEO and GEO are considered. The International Geomagnetic Reference Field is used to represent the local magnetic field strength vector at a given position on orbit. In the orbit prediction simulations, the specific charge of the test object is held constant. The results indicate a tendency for the Lorentz force to align the orbital plane with the geomagnetic equatorial plane. The limitation in the modeling methods associated with the use of the IGRF at high altitudes and the constant specific charge assumption are discussed. On-going and planned development work is outlined.
