Satellite Collection Graphics Attributes

You can control the graphical display of a satellite collection by going to Graphics > Attributes in the Satellite Collection properties. This properties page covers both 2D and 3D Graphics window attributes.

General graphics attributes

At the top of the page is a Show check box, which STK sets to selected by default. This means that STK will display the satellite collection in the 2D and 3D Graphics windows based on the settings in the subsets table below the check box. The following columns appear in the subsets table to enable you to control the graphics settings for each subset.

Column	Description
Subset	Lists all the subsets for the satellite collection. The subsets list comes from the Basic - Definition properties page for the satellite collection, so you cannot modify this list here.
Show	Select this check box to have STK display the satellites of a subset. The default is that this check box is selected for the AllSatellites subset but cleared for all other subsets.
Marker	Select the check box to have STK place a marker at the location of each satellite in the subset.
Marker Size	Specify the size of the satellite markers for the subset. The default value is 5.
Label	Select this check box to have STK place the satellite's name next to its marker for each satellite in the subset.
3D Orbits	Select this check box to have STK display the orbit path in the 3D Graphics window for all satellites in the subset.
Color	Select a color for the markers and orbit paths of each satellite in the subset.

2D Graphics window options

In the 2D Options pane, you can clear the Show Subsets in 2D Windows check box to have STK not display any subsets in the 2D Graphics window. The default is that this check box is selected, meaning STK displays all subsets.

3D Graphics window options

In the 3D Orbit Lines pane, you can specify the following orbit lines options:

Option	Description
Time Step	This is the step size for sampling the ephemeris to create position points along a satellite's orbit. STK then draws lines from point to point to create the orbit path display for the 3D Graphics window.
Reference System	This is the reference frame of the satellite orbit paths. The default is the Inertial frame for the central body. You can change the frame by clicking Select... and choosing a different system in the right column of the Select Orbit Lines System dialog box. This selection is for the satellite orbit paths only. The view of the 3D Graphics window as a whole will stay in the reference frame specified in the 3D Graphics window properties.
Interval to Show	Select one of the following options: One Period (default): The 3D Graphics window shows one orbital period for the orbit path of each satellite selected for display. Half of the path shown is before the current animation time, and half is after. If there isn't sufficient ephemeris to generate a half, then the window displays as much of the half as is possible. All ephemeris: The 3D Graphics window shows orbital paths covering the entire extent of the available ephemeris for each satellite selected for display. This could drive STK to display many orbital periods all at once, depending on the scenario.
