Type: Satellite
The satellite.
Type: System..::..DateTime
The start time.
Type: System..::..DateTime
The end time.
Type: System..::..Double
Distance, in kilometers, between each point in the ground track (approximate).
Type: System..::..Double
The desired height of the ground track points above the Earth ellipsoid model, in kilometers.

Return Value

A list of equidistant ECF coordinate points that define the subpoint locations of the satellite over the given time period. The last point in the list corresponds to time "t2" regardless of distance spacing.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Satellite. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
