IAgSnPtSpinning Interface

Description

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

Public Methods

Public Method SetClockAnglesSet both the start and stop clock angles. Start/Stop use Angle Dimension.

Public Properties

Public Property ClockAngleStartThe 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.
Public Property ClockAngleStopThe stop angle, i.e. the angle about the sensor's spin axis at which scanning ends and/or reverses direction. Uses Angle Dimension.
Public Property OffsetAngleThe initial offset angle, i.e. the angle about the spin axis where the sensor boresight is at time zero. Uses Angle Dimension.
Public Property ScanModeThe scan mode of the sensor, a member of the AgESnScanMode enumeration.
Public Property SpinAxisAzimuthThe 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.
Public Property SpinAxisConeAngleThe 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.
Public Property SpinAxisElevationThe 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.
Public Property SpinRateThe 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#]
// 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#]
// Configure sensor (using common taks)
sensor.CommonTasks.SetPointingSpinning(
    14.24,
    7.68,
    42.46,
    AgESnScanMode.eSnContinuous,
