Tudat contains various pieces of functionality of a purely mathematical nature, which are used to support the astrodynamics calculations. The setup of numerical integrators is discussed in the context of numerical state propagation. Below, additional mathematical functionality is documented.

  • Interpolators
    • General procedure
    • Available types of interpolators
    • Additional settings
