Adding and Defining STK Objects

You can add the following STK objects to a scenario using the Insert STK Objects tool, Object Catalog, or one of the object databases. All methods for adding an object are available from the Insert menu.

Use the Insert STK Objects tool to access all the methods available for inserting objects. The Insert STK Objects tool is automatically displayed when you create a new scenario using the New Scenario Wizard. If it does not automatically display, select Edit Preferences... and enable the display setting. You can also access the Insert STK Objects tool by clicking or selecting New... from the Insert menu.

Use the Object Catalog to create a default object. You can access the Object Catalog by clicking or selecting Object Catalog... from the Insert menu.

Icon	Object	Description
	AdvCAT	Provides a convenient way for you to carry out close approach analyses for multiple satellites and two-line element (TLE) sets.
	Aircraft	Models the properties and behavior of a vehicle that travels in a great arc route, generally above the surface of the earth.
	Antenna	Models the properties and behavior of an antenna.
	AreaTarget	Models a region on the surface of the central body.
	AttitudeCoverage	Combines the features of STK/Attitude and STK/Coverage to enable you to analyze coverage in various directions over time, using several attitude-dependent figures of merit.
	AttitudeFigureofMerit	Specifies the method by which the quality of coverage is measured.
	Chain	Models a list of objects (either individual or grouped into constellations) in order of access.
	CommSystem	Models dynamically configured communications links between constellations of transmitters and receivers.
	Constellation	Models a set of related objects.
	CoverageDefinition	Analyzes numerous coverage areas simultaneously.
	Facility	Models a ground station or other facility on the surface of the central body.
	Figure of Merit	Specifies the method by which the quality of coverage is measured.
	GroundVehicle	Models the properties and behavior of a vehicle that travels in a great arc route on surface of the earth. Identical to the Ship object.
	LaunchVehicle	Models the properties and behavior of a vehicle that follows an ascent trajectory from a launch point to an orbit insertion point.
	Line Target	Models a linear region of interest on the surface of the central body.
	MTO	Models multiple tracks of vehicles sharing the same properties and behavior, that travel in a great arc route.
	Missile	Models the properties and behavior of a vehicle following an elliptical path that begins and ends at the surface of the central body.
	Missile System	A missile system is a container for organizing the elements of a complex missile that is composed of multiple stages and/or reentry vehicles.  This object is primarily used through Connect by the Missile Modeling Tools (MMT) to minimize the clutter that would otherwise be caused in the Object Browser.  There are no analyses that can be performed on missile systems.
	Planet	Models orbital and other properties of a planet, a moon, an asteroid or the sun.
	Radar	Models the characteristics of a radar system and its environment.
	Receiver	Models the characteristics of a receiver, the antenna it uses and the environment in which it operates.
	Satellite	Models the properties and behavior of a vehicle in orbit around a central body.
	Sensor	Models the field of view and other properties of a sensing device attached to another STK object.
	Ship	Models the properties and behavior of a ship.
	Star	Models position, proper motion, annual parallax, visual magnitude and other properties of a star.
	Target	Models a point of interest on the surface of the central body. Except for some properties related to the STK/Conjunction Analysis Tools and STK/Communications modules, identical in properties and behavior to the Facility object.
	Transmitter	Models the characteristics of the transmitter, the antenna it uses and the environment in which it operates.
