Description
PART I
Using STK/Astrogator, create a scenario with a satellite orbiting the Earth. Follow the outlined procedure and answer the questions presented throughout. Helpful hints: SAVE YOUR
SCENARIO REGULARLY! Save each scenario in a separate folder. If you save multiple scenarios in the same folder, STK may overwrite data and you could lose your work.
-
Open STK and create a scenario using a start time of 1 Jan, 2020 00hr 00min 00s UTCG and stop time that is 1 day later by entering this information in the New Scenario Wizard screen. Select any name for your scenario, then click “OK”. The STK window will then update to appear as follows:
This window features both a 3D graphics window and a 2D ground track view (a projection of the satellite’s location on a body’s surface), with a panel on the left indicating the objects available within the STK scenario. Be sure to save this scenario by clicking the “Save” button or using the “File”à”Save” options within the menu. Be sure to press the save button
regularly!
-
Insert a satellite either by clicking the button highlighted by a red square in the figure below, located within the toolbar at the top of the window or accessing the “Insert”à”New…” option in the menu bar.
-
An “Insert STK Objects” popup should appear. Select the “Satellite” object on the left panel of this window and click the “Define Properties” method for inserting the object. These options are highlighted in the picture below. Once the desired object and insertion method have been

Title Page (1 pt.) – Lab, Course Number, Group Members, Date
Abstract (5pts) – short summary of objectives, experiment, results, and analysis
Introduction (5pts) – brief introduction to this lab, what you plan to investigate, how this could be applied
Within the writeup in the below sections, using subheadings such as “Question X” to clearly identify your answer to each question.
PART I: Earth Satellite Simulation (25 pts)
-
Description of scenario setup and initial parameters
-
Results and Analysis – for each question, show plots and summarize output generated from STK/Matlab, describe results, and briefly explain the theory (with equations as necessary).
-
Results and Analysis – include your Matlab code with a description of the script and justify choices for parameters/setup. Include a copy of your code in your report.
PART II: Lunar Surface Observation (45 pts)
-
Description of scenario setup and initial parameters
-
Theory – explain, with equations, how the initial condition is determined via calculations for the semi-major axis, eccentricity and true anomaly. Justify the sign of the true anomaly.
-
Theory – explain, with equations, the conversion between orbit position / true anomaly and time, where relevant. Include, where appropriate, a discussion to justify the sign of the true anomaly.
-
Results and Analysis – include your Matlab code with a description of the method used to solve Kepler’s equation and a description of the equations used. Be sure to justify any selected tolerances or initial guesses. Include a copy of your code in your report.
-
Results and Analysis – for each question, show all plots and summarize output generated from STK and describe results. Ensure that any plots are clear and 3D graphics views provide a useful perspective of the orbit. Justify your responses to any questions.
