VO Velocity Covariance

Set or modify Velocity Covariance graphics properties

Syntax

VO <VehObjectPath> VelocityCovariance {CovarOption} <Parameters>

Description

The VO Velocity Covariance commands enables you to define the graphical display of a 3D ellipsoid.

Valid values for {CovarOption} <Parameters> are:

{CovarOption}<Parameters>Description
Scale<ScaleValue>Uses the specified scale value to directly size the contour. Enter a value between 0 and 1.0e9.
UseProbability <ProbValue>Uses the specified percentage of probability encompassed by the ellipsoid to indirectly size the contour. Enter a value between 0.0 and 99.9.
Basic{AttrOption} <AttrValue> [{AttrOption2} <AttrValue2>...]To turn on the display of covariance graphics and assign graphics attributes. {AttrOption} and <AttrValue> are described in the table below.
Intervals{On | Off}Turn on or off the use of time intervals during which covariance graphics will display.
Load "<Filepath\Filename.int>"Clear the list of display intervals for covariance graphics, and replace them with the intervals specified in the interval file.

"<Filepath\Filename.int>" can be the path to a file on your local drive or the path to a file on an SDF server. See Specifying Paths for "<SDFFilePath>" syntax information.

Import "<TimeComponent>"Add the intervals specified in the Interval or Interval List "<TimeComponent>" to the list of display intervals for covariance graphics.

For information about "<TimeComponent>" see Component Specification.

Add <NumIntervals> "<StartTime>" "<StopTime>" ["<StartTime>" "<StopTime>"...] [{AttrOption} <AttrValue>...]Add time intervals during which covariance graphics will display to the list of existing intervals and assign their graphics attributes. {AttrOption} and <AttrValue> are described in the table below.
Replace <NumIntervals> "<StartTime>" "<StopTime>" ["<StartTime>" "<StopTime>"...] [{AttrOption} <AttrValue>...]Replace existing interval list with input intervals. {AttrOption} and <AttrValue> are described in the table below.
Remove "<StartTime>" "<StopTime>"Remove a single interval.
ClearRemove all intervals and turn interval graphics off.
IntervalDefault{AttrOption} <AttrValue> [{AttrOption2} <AttrValue2>...]Set the default attributes, or the display attributes that will be assigned to times between the specified time intervals. {AttrOption} and <AttrValue> are described in the table below.

{AttrOption} <AttrValue> can be:

{AttrOption} <AttrValue>Description
Show {On | Off}Set the option On or Off.
Color {Color}For valid {Color} options see Common Options.
LineWidth <Width> Indicate a pixel width value between 1.0 and 10.0.
Translucency <Value>Enter a value between 0 and 100 for the transparency.

Examples

VO */Satellite/attSat VelocityCovariance Scale 4.96
VO */Satellite/attSat VelocityCovariance Basic Show On Color blue LineWidth 4
VO */Satellite/attSat VelocityCovariance Basic Show On Color yellow Translucency 50

To turn on the use of intervals for velocity covariance graphics:

VO */Satellite/attSat VelocityCovariance Intervals On

To turn off the use of intervals:

VO */Satellite/attSat VelocityCovariance Intervals Off
VO */Satellite/CovarSat VelocityCovariance IntervalDefault Show Off Color blue LineWidth 2

To remove all intervals:

VO */Satellite/attSat VelocityCovariance Intervals Clear

To replace the existing intervals with the intervals in the Target1.int file:

VO */Satellite/attSat VelocityCovariance Intervals Load "c:\stk\project1\Target1.int"

To add two 1 hour and 20 minute intervals--one beginning at 12:38 a.m. and ending at 1:58 a.m. and the other beginning at 5:38 a.m. and ending at 6:58 a.m.:

VO */Satellite/attSat VelocityCovariance Intervals Add 2 "1 Jan 2001 00:38:00.00" "1 Jan 2001 01:58:00.00" "1 Jan 2001 05:38:00.00" "1 Jan 2001 06:58:00.00"

To remove the interval beginning at 12:40 a.m. and ending at 1:00 a.m.:

VO */Satellite/attSat VelocityCovariance Intervals Remove "1 Jan 2001 00:40:00.00" "1 Jan 2001 01:00:00.00"
VO */Satellite/attSat VelocityCovariance Intervals Replace 2 "1 Jan 2001 00:38:00.00" "1 Jan 2001 01:58:00.00" "1 Jan 2001 05:38:00.00" "1 Jan 2001 06:58:00.00"

To add two 1 hour and 20 minute intervals that will display as a green line of 3 pixel width--one beginning at 12:38 a.m. and ending at 1:58 a.m. and the other beginning at 5:38 a.m. and ending at 6:58 a.m.

VO */Satellite/attSat VelocityCovariance Intervals Add 2 "1 Jan 2001 00:38:00.00" "1 Jan 2001 01:58:00.00" "1 Jan 2001 05:38:00.00" "1 Jan 2001 06:58:00.00" Color green LineWidth 3

To add two 1 hour and 20 minute display intervals for velocity covariance graphics that will display as a magenta line of 2 pixel width--one beginning at 2:38 a.m. and ending at 3:58 a.m. and the other beginning at 7:38 a.m. and ending at 8:58 a.m.

VO */Satellite/attSat VelocityCovariance Intervals Add 2 "1 Jan 2001 02:38:00.00" "1 Jan 2001 03:58:00.00" "1 Jan 2001 07:38:00.00" "1 Jan 2001 08:58:00.00" Color magenta LineWidth 2
