LookAngleFrame Object

The LookAngleFrame object defines a 2D field-of-view with look angle coordinates. It contains an orientation, a boresight axis, look angle ranges, and definition for what each look angle axis represents.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Name	Description	Attributes
BoresightAxis	The axis of the transformed coordinate system which defines the boresight of the look angle frame coordinate system.	Type: Variable Access: Read/Write
DeclaredName	The name of the object as declared.	Type: String Access: Read-Only
Description	A description for the look angle frame.	Type: String Access: Read/Write
ID	A short string to identify the look angle frame.	Type: String Access: Read/Write
LookAngle1Label	A label for look angle 1.	Type: String Access: Read/Write
LookAngle1PlotReference	When plotting in this LookAngleFrame, this property determines if the look angle 1 axis goes from min-to-max or max-to-min.	Type: Variable Access: Read/Write
LookAngle1Range	The allowable range for look angle 1. The range is of the form: lower <= x <= upper.	Type: Array Access: Read/Write Units: deg
LookAngle1Type	The type of rotation represented by the first look angle with respect to the coordinate system defined by MountOrientation and NullOrientation.	Type: Variable Access: Read/Write
LookAngle2Label	A label for look angle 2.	Type: String Access: Read/Write
LookAngle2PlotReference	When plotting in this LookAngleFrame, this property determines if the look angle 2 axis goes from min-to-max or max-to-min.	Type: Variable Access: Read/Write
LookAngle2Range	The allowable range for look angle 2. The range is of the form: lower <= x <= upper.	Type: Array Access: Read/Write Units: deg
LookAngle2Type	The type of rotation represented by the second look angle with respect to the coordinate system defined by MountOrientation and NullOrientation.	Type: Variable Access: Read/Write
LookAngleMode	Determines whether the look angles represent rotations or displacements (Centerline-Horizontal-Vertical). Rotations are dependent and displacements are independent.	Type: Variable Access: Read/Write
MountOrientation	The orientation of the LookAngleFrame mount with respect to the Spacecraft body axis frame.	Type: Matrix Access: Read/Write
Name	The name displayed for this object in output windows such as views, plots, and reports.	Type: String Access: Read/Write
NullOrientation	A roll-pitch-roll sequence applied with respect to the MountOrientation describing the look angle frame coordinate system.	Type: Array Access: Read/Write Units: deg
ObjectId	The unique identifier for the object.	Type: Variable Access: Read-Only
ObjectType	The type of the object.	Type: String Access: Read-Only

Name	Description
CalculateLookAngles	Calculates the look angles for the calling LookAngleFrame to the target using the source as the position of the LookAngleFrame.
CalculateVectorFromAngles	Given a set of look angles, this method calculates a vector in the look angle frame.
ClearSavedStates	Clears previous saved states for this object.
GetBoresightVector	Returns the final vector based on the mounting matrix, null orientation, and boresight axis.
GetFromFile	Load the object state from the specified FreeFlyer object file.
GetFromString	Load the object state from the specified string.
PutToFile	Convert the object state to FreeFlyer object xml and write to a file.
PutToString	Convert the object state to FreeFlyer object xml and return as a string.
ReferenceEquals	Returns 1 if the argument refers to the calling object and 0 otherwise.
Restore	Restore an object's state from a previously saved state.
Save	Save the object's state so that it can be restored later.
