Unformatted text preview: obtained and plot the trajectory resulting from the following initial conditions: H = 600 km H = 0 . m/s = 28 deg and = 0 . deg/s = 10 deg = 0 . 06658 deg/s For these simulations, we assume that the Earth radius has a value Re = 6371 km , a mass of 5 . 9736 10 24 kg and that the value of the gravitational constant is G = 6 . 673 10-11 kg-1 .m 3 .s-2 . Plot the values of H , and as a function of time, as well as the resulting trajectory in Cartesian coordinates in both the Earth center frame rotating frame ( s 1 , s 2 , s 3 ) and an Earth center inertial frame. 1...
