% Model a spacecraft as an isothermal radiator with an input state. This model works only in Earth orbit. It has a second state for a flux modeled as a Markov process. -------------------------------------------------------------------------- Form: xDot = RHSIsothermal( x, t, d ) -------------------------------------------------------------------------- ------ Inputs ------ x (2,1) [Temperature;flux] t (1,1) TIme d (1,1) Data structure .a1 (1,1) epsilon*a_r/cp*m .a2 (1,1) alpha*a_s/cp*m .a3 (1,1) 1/cp*m .a4 (1,1) 1/tau .p (1,1) Internal power .jD0 (1,1) Julian date at t = 0 .rECI (3,1) ECI Position vector jD (1,n) Julian dates ------- Outputs ------- x (2,1) [Temperature;flux] --------------------------------------------------------------------------
