% Convert a relative state from the nu-domain to the time-domain. This changes only the relative velocity portion (elements 4 thru 6) of the state vector. For this conversion, the velocity terms are multiplied by the time-derivative of the true anomaly. Since version 7. -------------------------------------------------------------------------- Form: x = Nu2TimeDomain( x, n, e, nu ) -------------------------------------------------------------------------- ------ Inputs ------ x (6,1) Relative State in nu-domain, 6x1 vector, [position;velocity] n (1) Mean orbit rate [rad/s] e (1) Eccentricity nu (1) True anomaly [rad] ------- Outputs ------- x (6,1) Relative State in time-domain, 6x1 vector, [position;velocity] -------------------------------------------------------------------------- References: Inalhan, Tillerson, How, "Relative Dynamics and Control of Spacecraft Formations in Eccentric Orbits", Journal of Guidance, Control & Dynamics, Vol.25, No.1, Jan-Feb 2002. --------------------------------------------------------------------------
