Description

Look ahead and look behind duration options.

Public Properties

LookAhead	Look ahead duration: STK calculates attitude at a future point in time defined by adding the look ahead duration to the time of the most current data point. Uses Time Dimension. Valid value is between 1.0 and 1000000.0 seconds.
LookBehind	Look behind duration: specifies how long the temporary data points are to be stored by subtracting the look behind duration from the time of the most current data point. Uses Time Dimension.

Example

Configure real-time attitude

[C#] Copy Code

// set attitude type to real time 


satellite.SetAttitudeType(AgEVeAttitude.eAttitudeRealTime); 


IAgVeAttitudeRealTime realtime = satellite.Attitude as IAgVeAttitudeRealTime; 


 

// Set our Attitude Look Ahead method to Extrapolate 


realtime.LookAheadMethod = AgEVeLookAheadMethod.eExtrapolate; 


 

// Duration 


IAgVeDuration duration = realtime.Duration; 


duration.LookAhead = 1600.0; 

duration.LookBehind = 1600.0; 

 

// BlockFactor 


realtime.BlockFactor = 40; 

realtime.DataReference.SetProfileType(AgEVeProfile.eProfileInertiallyFixed);

Configure real-time attitude

[Visual Basic .NET] Copy Code

' set
attitude type to real time

satellite.SetAttitudeType(AgEVeAttitude.eAttitudeRealTime)

Dim realtime As IAgVeAttitudeRealTime =
TryCast(satellite.Attitude, IAgVeAttitudeRealTime)



' Set our Attitude Look Ahead method to
Extrapolate

realtime.LookAheadMethod = AgEVeLookAheadMethod.eExtrapolate



' Duration

Dim duration As IAgVeDuration = realtime.Duration

duration.LookAhead = 1600

duration.LookBehind = 1600



' BlockFactor

realtime.BlockFactor = 40

realtime.DataReference.SetProfileType(AgEVeProfile.eProfileInertiallyFixed)
