The Long-term Evolution of Geosynchronous Transfer Orbits

by

 

Interactive MATLAB script that predicts the long-term evolution of geosynchronous transfer orbits.

r2r (x)
function y = r2r (x)

% revolutions to radians function
   
% input

%  x = argument (revolutions; 0 <= x <= 1)

% output

%  y = equivalent x (radians; 0 <= y <= 2 pi)

% Orbital Mechanics with MATLAB

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

y = 2.0 * pi * (x - fix(x));
