Object Properties

Each STK object is comprised of a set of properties that define all of its characteristics that are relevant to the scenario. STK configures each object with a default set of property values when you create it, but most objects need to be configured more specifically to be useful for analysis. An object's properties are accessed using the Properties Browser.

Properties are grouped onto pages in collections of related properties; for example, the properties that define a satellite's orbit are grouped together on the Orbit page. The number and type of property pages that an object possesses are dependent on the object and, in some cases, additional STK licensing that you may have. In general there are four primary groups of properties - Basic, 2D Graphics, 3D Graphics, and Constraints.

  • Basic properties define the physical characteristics of the type of object selected, such as position, motion, and orientation.
  • 2D Graphics properties define the general elements of an object's display in the visualization windows, such as color, line style, and markers.
  • 3D Graphics properties define the three-dimensional elements of an object's display, such as the model, dynamic data display, and model pointing.
  • Constraint properties define conditions that must be met before links become available, such as visibility, lighting, and RF signal strength.
