Description

IAgSnPtSpinning Interface for defining the pointing properties of a spinning sensor.

Public Methods

Method to set both the start and stop clock angles. Start/Stop use Angle Dimension.

Public Properties

ClockAngleStart	The start angle, i.e. the angle about the sensor's spin axis at which scanning begins. Zero is relative to the X axis in the spin axis coordinate frame. Uses Angle Dimension.
ClockAngleStop	The stop angle, i.e. the angle about the sensor's spin axis at which scanning ends and/or reverses direction. Uses Angle Dimension.
OffsetAngle	The initial offset angle, i.e. the angle about the spin axis where the sensor boresight is at time zero. Uses Angle Dimension.
ScanMode	The scan mode of the sensor, a member of the AgESnScanMode enumeration.
SpinAxisAzimuth	The azimuth of the spin axis, i.e. the angle from the parent object's +X axis about the +Z axis in a right-handed sense. Uses Angle Dimension.
SpinAxisConeAngle	The cone angle used in defining the spin axis, i.e. the angle between the spin axis and the sensor boresight. As the boresight spins about the spin axis, it maintains this angular distance away from the spin axis. Uses Angle Dimension.
SpinAxisElevation	the elevation of the spin axis, i.e. the angle between the spin axis and the parent object's body-fixed XY plane, measured as positive in the direction of the parent object's body-fixed +Z axis. Uses Angle Dimension.
SpinRate	The spin rate, i.e. the rate at which the boresight spins about the spin axis, measured in revolutions per minute. The spin is positive in a right-handed sense about the spin axis. Negative rate can be used to create a spin in the opposite direction. Uses AngleRate Dimension.

Example

Define spinning sensor pointing

[C#] Copy Code

// Set pattern type to Spinning 

sensor.SetPointingType(AgESnPointing.eSnPtSpinning); 

IAgSnPtSpinning spinning = sensor.Pointing as IAgSnPtSpinning; 

 

// Configure sensor 

spinning.SpinAxisAzimuth = 14.24; 

spinning.SpinAxisElevation = 7.68; 

spinning.SpinAxisConeAngle = 42.46; 

spinning.ScanMode = AgESnScanMode.eSnContinuous; 

spinning.SpinRate = 88.921; 

spinning.OffsetAngle = 110.44;

Define spinning sensor pointing (using common tasks)

[C#] Copy Code

// Configure sensor (using common taks) 

sensor.CommonTasks.SetPointingSpinning( 

    14.24, 

    7.68, 

    42.46, 

    AgESnScanMode.eSnContinuous, 

    88.921, 

    110.44, 

    1.20, 

    3.50);

Define spinning sensor pointing

[Visual Basic .NET] Copy Code

' Set pattern type to Spinning
 sensor.SetPointingType(AgESnPointing.eSnPtSpinning)
Dim spinning As IAgSnPtSpinning = TryCast(sensor.Pointing, IAgSnPtSpinning)

' Configure sensor
 spinning.SpinAxisAzimuth = 14.24
 spinning.SpinAxisElevation = 7.68
 spinning.SpinAxisConeAngle = 42.46
 spinning.ScanMode = AgESnScanMode.eSnContinuous
 spinning.SpinRate = 88.921
 spinning.OffsetAngle = 110.44

Define spinning sensor pointing (using common tasks)

[Visual Basic .NET] Copy Code

' Configure sensor (using common taks)
 sensor.CommonTasks.SetPointingSpinning(14.24, 7.68, 42.46, AgESnScanMode.eSnContinuous, 88.921, 110.44, _
     1.2, 3.5)
