= Universal variable formulation
{wiki=Universal_variable_formulation}
Universal Variable Formulation (UVF) is a mathematical approach used in astrodynamics, particularly in the analysis of orbital mechanics and trajectory optimization. The formulation provides a way to describe the motion of a spacecraft or an object in space by using a set of universal variables that can simplify the computations involved in trajectory analysis. UVF is particularly beneficial for three-body problems, such as spacecraft flybys or transfers between celestial bodies, because it allows for the integration of equations of motion under varying gravitational influences.
