Measuring Number of Assets
N Asset Coverage measures the number of assets available simultaneously during coverage, where N is between zero and the total number of assets defined in the coverage definition.
The dynamic definition of N Asset Coverage computes the number of assets currently accessible to each grid point. The value is always an integer.
Compute options for N Asset Coverage
| Option | Description |
|---|---|
| Average | The average number of assets available to each point over the entire coverage interval. Value is a real number |
| Maximum | The maximum number of assets available over the entire coverage interval. Value is an integer |
| Minimum | The minimum number of assets available over the entire coverage interval. Value is an integer. Useful if the coverage definition contains a large number of assets |
| Percent Above | The value indicates that grid points are covered by at least N assets, X percent of the time, where N is the reported value and X is a percent level you specify |
| Unique | The number of unique assets which provide coverage at some point over the entire coverage interval. Value is an integer. |
Displaying N Asset Coverage in a Graphics Window
Graphics are used to represent the static and dynamic value of N Asset Coverage. Graphics representing the dynamic values are only displayed during animation. If Satisfaction is enabled, the graphics follow the general behavior for satisfaction graphics. If Satisfaction is disabled, the graphics appear as described in the following table:
The display of static graphics also depends on the Compute option set and the values entered in that field.
| Static or Animation? | Grid points highlighted if they... |
|---|---|
| Static | are covered by at least one asset at some point during the coverage interval |
| Animation | are currently covered by at least one asset |
An example satisfaction setting for this Figure Of Merit is to show points with simultaneous access to At Least 2 satellites. For this Figure Of Merit, the Satisfaction Threshold value is the number of satellites needed to provide coverage. The default behavior corresponds to a Satisfaction setting of Greater Than 0.
