Description

Properties for a Propagate segment.

Public Methods

DisableControlParameter	Disables the specified control parameter.
EnableControlParameter	Enables or disables the specified control parameter.
IsControlParameterEnabled	Sees if the specified control is enabled.

Public Properties

ControlParametersAvailable	Returns whether or not the control parameters can be set.
EnableMaxPropagationTime	If true, the maximum propagation time is enforced.
EnableWarningMessage	If true, Astrogator will issue a warning message if propagation is stopped by the Maximum Propagation Time parameter.
MaxPropagationTime	The maximum propagation time, after which the segment will end regardless of whether the stopping conditions have been satisfied. Uses Time Dimension.
MinPropagationTime	The minimum time that must elapse from the beginning of the segment until Astrogator will begin checking stopping conditions for satisfaction. Uses Time Dimension.
OverrideMaxPropagationTime	Override Maximum Propagation Time - if there is a duration or epoch stopping condition that occurs after the maximum propagation time, ignore the maximum propagation time.
PropagatorName	The propagator.
ShouldReinitializeSTMAtStartOfSegmentPropagation	If this segment is propagating the state transition matrix, reset it to the identity matrix at the start of the segment.
ShouldStopForInitiallySurpassedEpochStoppingConditions	Stop immediately if propagation begins beyond an active epoch stopping condition.
StoppingConditions	The list of stopping conditions defined for the segment.

Example

Configure propagate segment

[C#]

// Add a propagate segment to our sequence
IAgVAMCSSegment segment = driver.MainSequence.Insert(AgEVASegmentType.eVASegmentTypePropagate, "Propagate", "-");
IAgVAMCSPropagate propagate = segment as IAgVAMCSPropagate;
propagate.PropagatorName = "Earth Point Mass";

// Configure propagtor advanced properties
propagate.MinPropagationTime = 0;
propagate.EnableMaxPropagationTime = true;
propagate.MaxPropagationTime = 72000000;
propagate.EnableWarningMessage = true;

// Configure stopping conditions
IAgVAStoppingCondition duration = propagate.StoppingConditions["Duration"].Properties as IAgVAStoppingCondition;
duration.Trip = 7200;
duration.Tolerance = 0.00001;

// Add any addition stopping conditions
IAgVAStoppingCondition lightning = propagate.StoppingConditions.Add("Lighting") as IAgVAStoppingCondition;

Configure propagate segment

[Visual Basic .NET]

' Add a propagate segment to our sequence
Dim segment As IAgVAMCSSegment = driver.MainSequence.Insert(AgEVASegmentType.eVASegmentTypePropagate, "Propagate", "-")
Dim propagate As IAgVAMCSPropagate = TryCast(segment, IAgVAMCSPropagate)
propagate.PropagatorName = "Earth Point Mass"

' Configure propagtor advanced properties
propagate.MinPropagationTime = 0
propagate.EnableMaxPropagationTime = True
propagate.MaxPropagationTime = 72000000
propagate.EnableWarningMessage = True

' Configure stopping conditions
Dim duration As IAgVAStoppingCondition = TryCast(propagate.StoppingConditions("Duration").Properties, IAgVAStoppingCondition)
duration.Trip = 7200
duration.Tolerance = 1E-05

' Add any addition stopping conditions
Dim lightning As IAgVAStoppingCondition = TryCast(propagate.StoppingConditions.Add("Lighting"), IAgVAStoppingCondition)

Insert a Propagate State Segment into the MCS and configure

[MATLAB]

% IAgVADriverMCS driver: MCS driver interface
propagate = driver.MainSequence.Insert('eVASegmentTypePropagate', 'Propagate', '-');
propagate.PropagatorName = 'Earth Point Mass';
propagate.Properties.Color = 16711680;  % Blue
propagate.StoppingConditions.Item('Duration').Properties.Trip = 7200;

Insert a Propagate State Segment into the MCS and Add/Remove Stopping Conditions

[MATLAB]

% IAgVADriverMCS driver: MCS driver interface
transferEllipse = driver.MainSequence.Insert('eVASegmentTypePropagate', 'Transfer Ellipse', '-');

transferEllipse.Properties.Color = 255; % Red
transferEllipse.PropagatorName = 'Earth Point Mass';
transferEllipse.StoppingConditions.Add('Apoapsis');
transferEllipse.StoppingConditions.Remove('Duration');
