Closed form magnetic quarter orbit switch point solution
Abstract
A closed form solution is derived for determining the location of a set of magnetic switch points, spaced 90 deg apart in the orbit, which will allow the spin axis of a satellite to be moved in any, achievable, desired direction from any initial orientation. Additional closed form equations are derived for determining the magnitude of the motion that will result for a given set of switch points. The simplicity of the calculations makes the technique extremely useful for applications where savings in computer time or storage are desired and for design studies where quick solutions to many cases are required.
