The Sensor Object
The Sensor object models the field of view and other properties of a sensing device attached to another STK object. Select one or more of the following to model a Sensor and impose constraints:
Basic Properties
| Property |
Description |
| Definition
|
Set parameters defining a sensor's field of view. |
| Location
|
Position a sensor with respect to its parent object. |
| Pointing
|
Set parameters to determine how a sensor is aimed, e.g., with respect to its parent object, the central body, objects selected for tracking, etc. |
| Sensor AzEl Mask
|
Define an azimuth-elevation mask for the sensor. |
| Refraction
|
Select a refraction model to constrain an atmosphere-based sensor's line of sight and elevation angles. |
| Resolution
|
Define the resolution of the sensor in terms of focus and image quality. |
| Description
|
Record useful information about the sensor. |
2D Graphics Properties
| Property |
Description |
| Attributes
|
Define color, line style and other graphics characteristics for the sensor, and opt whether to inherit or override global attributes defined at the Scenario level. |
| Projection
|
Control the display of sensor projection graphics. |
| Boresight
|
Control the display of sensor boresight graphics. |
| Display Times
|
Set time intervals during which sensor graphics display. |
3D Graphics Properties
| Property |
Description |
| Attributes |
Control the display of a sensor in the 3D graphics window. |
| Projection
|
Control the display of a sensor's cone into space as well as the sensor's extension into space. |
| Pulse
|
Modulate a sensor's projection. |
| Vertex Offset
|
Enable the projection for a sensor to be offset from the sensor parent object's actual position in the parent's body coordinate frame. |
| Vector
|
Control the display of vectors and other geometric elements related to the sensor. |
| Attitude Sphere
|
The Attitude Sphere is a visualization aid that when combined with vector display constitutes a powerful tool for displaying the object's attitude and for tracking attitude changes over time. |
| Data Display |
Display dynamic data for the sensor in the 3D Graphics window. |
Constraints Properties
| Property |
Description |
| Basic
|
Impose minimum elevation and line-of-sight constraints on access from the sensor to another object. |
| Sun
|
Impose a variety of access constraints from the sensor to another object based on the position of the Sun and the Moon. |
| Temporal
|
Impose time-based access constraints from the sensor to another object. |
| Advanced
|
impose a variety of sensor-specific constraints. |
| Zones
|
Use inclusion and exclusion zones to define areas where access is or is not allowed. |
| Resolution
|
Limit access based on sensor characteristics and the quality of the inview. |
| Targeting
|
Define the relationship between the sensor and the target of that sensor. |
| 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.
|
| EOIR
|
Set a signal-to-noise ratio (SNR) on an EOIR sensor. |
