Magnetic effects of satellites should be carefully studied starting from the design phase by creating a stringent magnetic cleanliness program. This program is required to maintain DC magnetic compatibility between units and reduce the interaction of satellite magnetic field with external magnetic field resulting parasitic torques. DC magnetic compatibility is especially important for satellites aiming scientific missions requiring sensitive magnetic equipment. Magnetic behavior of satellites and its units can be understood by test and analysis. Although testing is the most reliable method to evaluate magnetic assessment quantitatively, analysis becomes the first step because of cost and time restrictions. In this study, common analysis methods such as centered dipole approximation, multiple dipole modeling, spherical harmonics methods are discussed for their powerful and weak points. © 2016 Wiley Periodicals, Inc.
