The Transmitter Object
The Transmitter object models the characteristics of the transmitter, the antenna it uses, and the environment in which it operates. Select one or more of the following to model a transmitter and impose constraints:
Basic Properties
| Property |
Description |
| Definition
|
Define the characteristics of the transmitter. |
| Refraction
|
Model atmospheric refraction. |
| Description
|
Record useful information about the antenna. |
2D Graphics Properties
| Property |
Description |
| Contours
|
Define the display of contour lines and transmitter patterns. |
| Boresight
|
Define the display of boresight graphics. |
3D Graphics Properties
| Property |
Description |
| Attributes
|
Control the display of contour lines and transmitter patterns. |
| Vector
|
Control the display of vectors and other geometric elements related to the transmitter. |
Constraints
| Property |
Description |
| Basic
|
Impose minimum elevation and line-of-sight constraints on access from the transmitter to another object. |
| Noise
|
Impose constraints on a transmitter related to system noise temperature. |
| Comm
|
Impose a variety of communications link constraints on the transmitter. |
| Interference
|
Set constraints in terms of certain link performance indicators as affected by interference. |
| Sun
|
Impose a variety of access constraints from the transmitter to another object based on the position of the Sun and the Moon. |
| Temporal
|
Impose time-based access constraints from the transmitter to another object. |
| Advanced
|
impose a variety of transmitter-specific constraints. |
| Zones
|
Use inclusion and exclusion zones to define areas where access is or is not allowed. |
| Targeting
|
Define the relationship between the transmitter and the target of that transmitter. |
| 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 VBScript and MATLAB. |
RF Properties

LASER Properties
| Property |
Description |
| Environment
|
