The Coverage capability allows you to analyze numerous coverage areas simultaneously. Simply set up a CoverageDefinition object for each area of interest. Also, if you intend to analyze more than one set of contingencies for a given area, you can set up multiple CoverageDefinition objects for that area, with each object representing a different set of contingencies. A coverage definition object is defined by selecting the area(s) of interest, identifying the assets that may provide coverage to those areas, and setting the time period over which coverage statistics are to be analyzed. Once the coverage definition object is defined, access periods to the coverage area can be computed to determine the availability of an asset or set of assets that satisfy all geometric, lighting, temporal and other user-specified constraints.
The constraints applied to a coverage analysis can be associated with the coverage assets or with the definition of the coverage area. While only one set of constraints can be associated with a coverage definition, multiple coverage definitions can be defined to model different constraints associated with the coverage area. The following table provides a brief example of situations where a single or multiple coverage definitions are required.
| Requirements | Single | Multiple |
|---|---|---|
| Single region, uniform constraints | X | |
| Multiple regions, uniform constraints | X | |
| Multiple regions, uniform constraints, multiple quality measures | X | |
| Single region, several sets of constraints | X | |
| Multiple regions, several sets of constraints | X |
You can also display a graphical representation of the area as well as graphics that show the progress of coverage calculations in a graphics window.
To define a coverage area and its Basic properties, first create a coverage definition object (
), then, right-click the object, and select Properties Browser from the pop-up menu. Use the Basic properties available to define the coverage definition object.
The Description page is a basic property of all STK objects.
