LineTarget
Available Data Providers
| Name | Description |
|---|---|
| Active Constraints | Lists the constraints that are considered when computing access for the object. |
| All Constraints | Descriptions of all constraints available for this object and its parent object. |
| Anchor Point All Position | Position data for the line target's anchor point in different element representations computed in the line target's central body fixed coordinate system. |
| Anchor Point Eclipse Times | Generates a listing of all eclipse times. Eclipsing times are start and end of periods of partial lighting (penumbra) and periods of zero lighting (umbra). |
| Anchor Point Lighting AER | Angle and range data describing the apparent position vector of the Sun relative to the anchor point. The data is reported in the line target's Local horizontal frame. This frame has the Z axis aligned with the inward surface normal direction (minus Z is up) and the X axis constrained toward the local north direction. |
| Anchor Point Lighting Times | Generates a listing of all lighting events. Lighting events are start and end of periods of full lighting (sunlight), partial lighting (penumbra) and periods of zero lighting (umbra). Note that the Lighting Times data provider reports all computed penumbra intervals, which means that if umbra exists, then two penumbra intervals, each with its own start and stop times, is reported--one before and one after the umbra interval. So, if lighting times that start in umbra are generated, then the first reported penumbra interval corresponds to the times that follow after the first umbra, and the penumbra interval prior to the first umbra is not reported. |
| Anchor Point Solar Intensity | Percent of the solar disc visible, along with lighting condition and name of obscuring central body. |
| Angles | Reports angle and its time rate of change rate. Angle must be defined in the Vector Geometry Tool. |
| Available Times | The time intervals over which the object is available to participate in access computations. |
| Axes Choose Axes | Reports the orientation and angular velocity of the selected set of axes relative to a chosen reference set of axes. The selected set of axes can be selected from any axes in the Vector Geometry Tool owned by the object; the reference axes may be chosen from any axes in the Vector Geometry Tool. |
| Body Axes Orientation | Reports the orientation and angular velocity of the Body axes of the object with respect to a selected reference set of axes.
The reference set of axes can be selected from any axes in the Vector Geometry Tool owned by the object.
Selecting the Body axes as the reference axes results in no orientation difference nor any angular velocity between the Body axes and this reference axes. |
| Body Axes Orientation:YPR 123 | Reports the orientation and angular velocity of the Body axes of the object with respect to a selected reference set of axes, where
the Yaw, Pitch, and Roll angles are defined using the YPR 123 sequence. The reference set of axes can be selected from any axes in the Vector Geometry Tool owned by the object.
Similar to Euler angles, YPR angles specify attitude using three rotations in sequence: a rotation about the reference X axis is called roll (R), a rotation about the reference Y axis is called pitch (P), and a rotation about the reference Z axis is called yaw (Y). Unlike Euler angles, the rotations are not made about axes defined by an earlier rotation: each rotation is made about the reference system's axes. As used in YPR angles, the names yaw, pitch, and roll do not refer to the angles normally used in aviation; the terms yaw, pitch, and roll in aviation refer to 321 Euler angles. Selecting the Body axes as the reference axes results in no orientation difference nor any angular velocity between the Body axes and this reference axes. |
