The Antenna Object

The Antenna object models the properties and behavior of an antenna. Select one or more of the following to model an antenna and impose constraints:

Basic Properties

Property Description
Definition Define the characteristics of the antenna.
Orientation Specify the orientation of the antenna coordinate frame relative to the coordinate frame of the parent object.
Refraction Model atmospheric refraction.
Description Record useful information about the antenna.

2D Graphics Properties

Property Description
Contours Define the display of contour lines and antenna patterns.
Boresight Define the display of boresight graphics.

3D Graphics Properties

Property Description
Attributes Control the display of contour lines and antenna patterns.
Vector Control the display of vectors and other geometric elements related to the antenna.

Constraints

Property Description
Basic Impose minimum elevation and line-of-sight constraints on access from the antenna to another object.
Sun Impose a variety of access constraints from the antenna to another object based on the position of the Sun and the Moon.
Temporal Impose time-based access constraints from an antenna to another object.
Zones Use inclusion and exclusion zones to define areas where access is or is not allowed. Aircraft only.
Vector Constrain access computations with respect to any valid vector or angle.
Special Special access constraints are defined in terms of geostationary belt exclusion, height above horizon, terrain grazing angle and exclusion of other scenario objects.
Plugins An interface is provided for defining custom constraints in terms of user-supplied scripts created in Perl, VBScript and MATLAB.
