The Area Target Object

The Area Target object models a region on the surface of the central body. Select one or more of the following to model an Area Target and impose constraints:

The boundary of an area target extends infinitely and geodetically above the ellipsoid when used in Access calculations.

Basic Properties

Property Description
Boundary Define the area target as a pattern bound by selected points or as an ellipse with specified parameters.
Centroid Define a 'center' point for the area target to be used as, among other things, a terminal point for access lines drawn to the area target during animation.
Processing Delay The summed time values of the processing delays specified by each object in the strand plus the light time delay between object pairs in the strand. The light time delay between object pairs is computed simply based on the objects positions divided by the speed of light.
Description Record useful information about the area target.

2D Graphics Properties

Property Description
Attributes Define color, line style and other graphics characteristics for the area target, and opt whether to inherit or override global attributes defined at the Scenario level.
Display Times Set time intervals during which area target graphics display.

3D Graphics Properties

Property Description
Attributes Define color, line style and other graphics characteristics for the area target, and opt whether to inherit or override attributes defined at the 2D Graphics level.
Vector Control the display of vectors and other geometric elements related to the line target.

Constraints

Property Description
Active

Impose constraints on access from the following available constraint categories for an Area Target object:

  • Basic: The most commonly used constraints
  • Geometry: Constraints that use a geometric measure (other than angle), such as range, altitude, and grazing altitude
  • Analysis Workbench (AWB): Constraints that involve an Analysis Workbench (AWB) component (Angle, Calculation Scalar, Condition, or Vector)
  • Plugins: Your own plugin constraints, which compute a plugin-defined metric that you define
  • Temporal: Constraints related to specified time-of-day or time intervals
Settings Select access constraint conditions that apply generally to access computations involving this Area Target object.
