| Abstract | ||||
| A model was designed and built using The Mathworks’ SIMULINK to simulate the properties of the lower and upper atmosphere. The lower atmosphere is based on the US Standard Atmosphere 19761,2,3, which predicts the properties of the troposphere, stratosphere, mesosphere, and their inter-pauses. The upper atmosphere is based on NASA Marshall Engineering Thermosphere (MET-2)4, which predicts the properties of the ionosphere, thermosphere, and exosphere. A fairing is provided for smooth transition between the lower atmosphere, which ends at 84.852km, and the upper atmosphere, which begins at 90km. The model simulation results are in excellent agreement with NASA’s MET-2 FORTRAN 77 code results. | ||||
