Description

Object Model

Public Methods

GetAccessBetweenObjectsByPath	Returns the access object currently associated with the two STK objects specified using their paths. The paths can be fully-qualified or truncated.
GetExistingAccesses	Returns an array of existing accesses in the current scenario. The result is a two-dimensional array of triplets where each triplet contains the paths of two objects participating in the access and a flag indicating whether the access is computed.
SetDirty	Sets the flag indicating the scenario has been modified.
SetTimePeriod	Method to set the Scenario time period. startTime/stopTime use DateFormat Dimension.

Public Properties

AcWGS84Warning	Specify when to display the aircraft mission modeler WGS84 warning.
AnalysisEpoch	Allows the user to configure the scenario's analysis epoch.
AnalysisInterval	Allows the user to configure the scenario's analysis time period.
Animation	Scenario animation settings.
ComponentDirectory	The component directory interface
EarthData	Scenario Earth Data settings.
Epoch	Scenario epoch. Uses DateFormat Dimension.
GenDbs	Scenario database settings.
Graphics	Scenario 2D Graphics settings.
IsDirty	Specify whether scenario needs to be saved
MslNoOrbitWarning	Specify whether to display a warning when a missile trajectory does not impact the central body.
MslStopTimeWarning	Generate a message that warns the user if the missile achieves orbit (and give the perigee) or impacts the surface (and give the interval after missile's stop time).
RadarClutterMap	Returns the global radar clutter map.
RadarCrossSection	Returns the global radar cross section.
RFEnvironment	Returns the RF environment.
SatNoOrbitWarning	Specify whether to display a warning when a satellite orbit intersects the central body.
ScenarioFiles	Returns list of scenario files.
SceneManager	A scene manager.
SpaceEnvironment	Scenario SpaceEnvironment settings.
StartTime	Scenario start time. Uses DateFormat Dimension.
StopTime	Scenario stop time. Uses DateFormat Dimension.
Terrain	Returns a list of central bodies and their terrains.
UseAnalysisStartTimeForEpoch	Whether the scenario Epoch is the same as the scenario's StartTime.
VO	Scenario 3D Graphics settings.

Example

GetAccessBetweenObjectsByPath using the output of GetExistingAccesses

[C#]

Copy Code

IAgScenario scenario = stkRoot.CurrentScenario as IAgScenario;  Array accesses = scenario.GetExistingAccesses();    int numAccesses = accesses.GetLength(0);  // number of accesses    string object1 = accesses.GetValue(0, 0).ToString();    // e.g. "Facility/Fac1"  string object2 = accesses.GetValue(0, 1).ToString();    // e.g. "Satellite/Sat1"  bool computed = (bool)accesses.GetValue(0, 2);          // e.g. true  (if access has been computed)    IAgStkAccess access = scenario.GetAccessBetweenObjectsByPath(object1, object2);

Copy Code

IAgSatellite satellite = stkRoot.GetObjectFromPath("/Satellite/GeoEye") as IAgSatellite;    IAgCrdnProvider vgtProvider = stkRoot.VgtRoot.GetProvider("/Satellite/GeoEye");  IAgVePropagatorTwoBody twoBody = satellite.Propagator as IAgVePropagatorTwoBody;  IAgCrdnEventSmartEpoch startEpoch = twoBody.EphemerisInterval.GetStartEpoch();  IAgCrdnEventSmartEpoch stopEpoch = twoBody.EphemerisInterval.GetStopEpoch();    scenario.AnalysisInterval.SetStartAndStopEpochs(startEpoch, stopEpoch);

Sets the scenario analysis time to today and the duration to one day.

[C#]	Copy Code
scenario.AnalysisInterval.SetStartTimeAndDuration("Today", "+1 Day");
