Analyzing “integral indices” to quantify the effects of a perturbing force over satellites

Integral indices are useful tools to be used to identify characteristics of an orbit. Using analytical solutions for a perturbative version of the Tsien problem (radial low thrust applied to a spacecraft), two indices are defined and evaluated. They can make a map of the orbits disturbed by the thru...

Description
Summary:Integral indices are useful tools to be used to identify characteristics of an orbit. Using analytical solutions for a perturbative version of the Tsien problem (radial low thrust applied to a spacecraft), two indices are defined and evaluated. They can make a map of the orbits disturbed by the thrust. •Measuring the influence of the perturbation on the trajectory and velocity.•Perturbation solution to the Tsien problem - low, constant and radial thrust.•Defining useful “integral indices” to be used in astrodynamic problems.
