OrbitDisturbanceEstimator:

Path: SpacecraftEstimation/Demos/OrbitEstimation

% Demonstrates orbit disturbance estimation using linearized equations. 
 This uses the linearized orbit equations in-plane. A radial disturbance 
 is modeled and estimated. The equations are normalized so that the 
 derivative is respect to wo*t instead of t. This improves the numerical 
 properties of the state transition matrix which otherwise would cause DQCE 
 to fail. DQCE has an inverse in it which is not particularly robust 
 numerically. Generally, this kind of scaling is always a  good idea.
