Description

One Point Access.

Public Methods

Compute	Computes one point access results using the StartTime, StopTime, StepSize, and SummaryOption.
ComputeFirstSatisfaction	Computes and reports the first N satisfaction intervals (where N <= MaxNumAccessesToFind) over the specified interval whose spans meet the specified minimum duration. Does not use output file.
Remove	Removes the one point access component that was created.

Public Properties

OutputFile	If set to do so, results will be output to a file with this name.
OutputToFile	Whether to output to a file.
StartTime	Gets or sets the start time. Uses current animation time if none is entered.
StepSize	Gets or sets the step size. Default is 60 seconds.
StopTime	Gets or sets the stop time. Uses current animation time if none is entered. Set this to the same value as StartTime to report at a single time.
SummaryOption	Summary option that specifies the level of detail to provide in the computed results.

Example

Compute an access for one point

[C#]

IAgOnePtAccess onePtAccess = facility.CreateOnePointAccess("Satellite/Satellite1");

// Configure properties (if necessary)
onePtAccess.StartTime = "1 Jan 2012 12:00:00.000";
onePtAccess.StopTime = "1 Jan 2012 13:00:00.000";
onePtAccess.StepSize = 120;
onePtAccess.SummaryOption = AgEOnePtAccessSummary.eOnePtAccessSummaryDetailed;

// Compute results
IAgOnePtAccessResultCollection results = onePtAccess.Compute();

// Print results
for (int i = 0; i < results.Count; i++)
{
    IAgOnePtAccessResult result = results[i];

    Console.WriteLine("Time: {0}, HasAccess: {1}", result.Time, result.AccessSatisfied);

    for (int j = 0; j < result.Constraints.Count; j++)
    {
        IAgOnePtAccessConstraint constraint = result.Constraints[j];
        Console.WriteLine("Constraint: {0}, Object {1}, Status {2}, Value {3}",
            constraint.Constraint,
            constraint.ObjectPath,
            constraint.Status,
            constraint.Value);
    }
}

Compute an access for one point

[Visual Basic .NET]

Dim onePtAccess As IAgOnePtAccess = facility.CreateOnePointAccess("Satellite/Satellite1")

' Configure properties (if necessary)
onePtAccess.StartTime = "1 Jan 2012 12:00:00.000"
onePtAccess.StopTime = "1 Jan 2012 13:00:00.000"
onePtAccess.StepSize = 120
onePtAccess.SummaryOption = AgEOnePtAccessSummary.eOnePtAccessSummaryDetailed

' Compute results
Dim results As IAgOnePtAccessResultCollection = onePtAccess.Compute()

' Print results
Dim i As Integer = 0
While i < results.Count
	Dim result As IAgOnePtAccessResult = results(i)

	Console.WriteLine("Time: {0}, HasAccess: {1}", result.Time, result.AccessSatisfied)

	Dim j As Integer = 0
	While j < result.Constraints.Count
		Dim constraint As IAgOnePtAccessConstraint = result.Constraints(j)
		Console.WriteLine("Constraint: {0}, Object {1}, Status {2}, Value {3}", constraint.Constraint, constraint.ObjectPath, constraint.Status, constraint.Value)
		System.Math.Max(System.Threading.Interlocked.Increment(j),j - 1)
	End While
	System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
End While

Compute an access for one point

[Python - STK API]

# IAgStkObject facility: Facility object
onePtAccess = facility.CreateOnePointAccess('Satellite/MySatellite')

# Configure properties (if necessary)
onePtAccess.StartTime = root.CurrentScenario.StartTime
onePtAccess.StopTime = root.CurrentScenario.StopTime
onePtAccess.StepSize = 600
onePtAccess.SummaryOption = AgEOnePtAccessSummary.eOnePtAccessSummaryDetailed

# Compute results
results = onePtAccess.Compute()

# Print results
for i in range(0, results.Count):
    result = results.Item(i)
    print('Time: %s HasAccess: %s' % (result.Time, str(result.AccessSatisfied)))

    for j in range(0, result.Constraints.Count):
        constraint = result.Constraints.Item(j)
        print('Constraint: %s Object: %s Status: %s Value:%s' % (constraint.Constraint, constraint.ObjectPath, constraint.Status, str(constraint.Value)))

Compute an access for one point

[MATLAB]

% IAgStkObject facility: Facility object
onePtAccess = facility.CreateOnePointAccess('Satellite/MySatellite');

% Configure properties (if necessary)
onePtAccess.StartTime = root.CurrentScenario.StartTime;
onePtAccess.StopTime = root.CurrentScenario.stopTime;
onePtAccess.StepSize = 600;
onePtAccess.SummaryOption = 'eOnePtAccessSummaryDetailed';

% Compute results
results = onePtAccess.Compute();

% Print results
for i = 0:results.Count - 1
    result = results.Item(i);
    disp(['Time: ' result.Time ' HasAccess: ' num2str(result.AccessSatisfied)]);

    for j = 0:result.Constraints.Count - 1
        constraint = result.Constraints.Item(j);
        disp(['Constraint: ' constraint.Constraint ' Object: ' constraint.ObjectPath ' Status: ' constraint.Status ' Value: ' num2str(constraint.Value)]);
    end
