Measuring Response Time
STK's Coverage capability uses an "optimistic" algorithm when coverage gaps that share a boundary with the coverage interval exist. The span of the coverage gap is measured using the coverage interval bound. This is important for the correct interpretation of the Age Of Data, Revisit Time, Time Average Gap, and Response Time figures of merit.
Use the Min # Assets text box to enter the the minimum number of assets required for the Coverage object.
Displaying Response Time in a graphics window
STK uses graphics to represent the static and dynamic value of Response Time, but only during animation. If you select the Satisfaction check box, the graphics follow the general behavior for satisfaction graphics. If you do not select the check box, the graphics appear as described in the following table:
Static or Animation? | Grid points highlighted if they... |
---|---|
Static | are in a coverage gap at least once during the coverage interval |
Animation | are currently in a coverage gap |
The Satisfaction Threshold value is the time between a request for coverage of a point and the achievement of that request. The default behavior for this Figure Of Merit corresponds to a Satisfaction setting of Greater Than 0.
