Description

Access or create VGT systems associated with an object or a central body.

Object Model

Public Methods

Contains	Searches for a an element with a given name. Returns false if the specified element does not exist.
Remove	Removes a specified System.

Public Properties

CommonTasks	Provides access to common tasks that allow users quickly carry out tasks such as creating known systems, etc.
Context	Returns a context object. The context can be used to find out which central body or STK object this instance is associated with.
Count	Returns a number of elements in the collection.
Factory	Returns a Factory object used to create custom VGT systems.
Item	Returns a System by name or at a specified position.

Example

Enumerate the existing systems.

[C#] Copy Code

// Enumerate the existing Systems using specified CrdnProvider. 


foreach (IAgCrdnSystem system in provider.Systems) 


{ 

    // All systems implement IAgCrdn interface which provides 


    // information about the system instance and its type. 


    IAgCrdn crdn = system as IAgCrdn; 


    Console.WriteLine("Name: {0}, type: {1}", crdn.Name, system.Type); 


}

Iterate through existing systems (coordinate reference frames).
