What is a Scenario?

A scenario in STK is an instance of an analytical or operational task that you are modeling with STK. In STK, a scenario is represented by an icon of an idealized "scene", as shown below:

When you select Save from the File menu in STK, you are saving a scenario. However, unlike other applications that save a single file, STK saves a scenario as a group of files that comprise the collection of objects that are relevant to the scenario. The following image shows an instance of a saved scenario.

Scenario Files

When you save a scenario, the scenario itself is saved as an object, and each object within the scenario is saved individually. The file extension for the scenario object is ".sc". Additionally, the current layout of your workspace is saved in a Workbook file.

Satellites, aircraft, ground vehicles, ships, planets, stars, receivers and transmitters are examples of the objects that can constitute a scenario in STK. Within a scenario, you can set general properties, such as time period, units of measure, and the appearance of the 2D and 3D windows. Information that is contained in the scenario can be used to create reports and to perform other analytical tasks.

You can create an unlimited number of scenarios with STK; however, only one scenario can be open at a time.

All objects that you can add to a scenario are found in the Object Catalog, shown below

Object Catalog

To build a scenario, select objects from the Object Catalog and set their properties. When you add an object to a scenario, it appears in the Object Browser, shown below. Then the object can be named and properties can be set.
