% Find the standard deviation of along-track drift per orbit due to rel nav errors. Type DriftRateSigma for a demo. -------------------------------------------------------------------------- Form: sigma_d = DriftRateSigma( a, sigma_x, sigma_ydot, rho_xydot ); -------------------------------------------------------------------------- ------ Inputs ------ a (1) Semi-major axis of orbit [km] sigma_x (1) Standard deviation of relative radial position error sigma_ydot (1) Standard deviation of relative along-track velocity error rho_xydot (1) Correlation coefficient (between -1 and +1) ------- Outputs ------- sigma_d (1) Standard deviation of the along-track drift per orbit --------------------------------------------------------------------------
