Overview
Welcome to the STK Fundamentals training course.This course is a collection of
instructor-led exercises that provide hands-on experience with a variety of the
features and functions on which STK is built. It will familiarize the first-time user
with the AGI Graphical User Interface (GUI); introduce them to some of the
various land, sea, air, and space objects; their associated properties, and tools;
and leave them with a basic understanding of the capabilities that are a part of the
Satellite Tool Kit (STK) ® software suite.
This is not a comprehensive guide to any of the products that make up the STK
Product Suite. The full scope of the STK Product Suite is far too broad to address
in a single day course. When you complete this course, you will have the
knowledge that you need to navigate the software and access additional
resources including the STK Help system, which contains in-depth information
about operating STK and all of its associated modules and add-ons.
This course will focus on the core modules that are commonly used to perform
various types of analysis. In order to complete the exercises herein you must
have a fully functional copy of the following products:

When Can I Spy On Washington
From a Molniya Satellite?
EXERCISE 1
In this exercise you will create a simple scenario that will help you get acquainted with
navigating through the STK Graphical User Interface (GUI) and achieve some key
objectives. Upon completion, you will be able to:
• Understand the questions that STK answers:
Where am I? What can I see? When can I see it?
Insert and position an object using an STK database.
• Use the Orbit Wizard.
•
• Move around in the 2D and 3D Graphics windows.
• Calculate a simple line-of-sight access.
When Can I Spy On Washington From a Molniya Satellite?
Problem Statement
It is said that the Molniya orbit is a great way to spy on the United States.
During such a spacecraft’s two (2) twelve (12) hour daily orbits, how many
hours a day can a Molniya satellite actually see Washington?
BREAK IT DOWN
You have some information that may be helpful. Here’s what you know:
• There are two “players” in the scenario--a spacecraft traveling in a Molniya
orbit and the city of Washington.
• A Molniya orbit has two (2) twelve (12) hour daily orbits.
• You want to know if and when a Molniya satellite can “see” Washington.
SOLUTION
Build an STK scenario that allows you to calculate a simple line-of-sight access
between a spacecraft traveling in a Molniya orbit and Washington, D.C so that
you can tell at what points along the spacecraft’s orbit it can “see”
Washington.
Welcome To STK!
The first thing you need to do is launch STK, and create a new scenario.
1. Double-click the STK icon (
) on the desktop.
Everything in STK begins with a scenario. A scenario is STK's name for an
instance of an analytical or operational task being modeled using STK. In
STK a scenario is represented by an icon of an idealized “scene”. The STK
scenario creates the context, or environment, within which all other objects in
the scenario exist. You can create an unlimited number of scenarios with
STK, however only one scenario can be open at a time.
When STK launches, the Welcome to STK! dialog (the Welcome Dialog) will
appear. Using the options available here, you can create new scenarios, open
exiting scenarios, access the STK Help System, or exit the STK application.
