Time of calculation, in minutes-past-epoch.
The viewing angle, from the earth to the satellite, [0..90] degrees.
The distance between each point, in kilometers.
The height of the set of points above the Earth ellipsoid model, in kilometers.
Return ValueA list of ECF coordinate points that form a circle on the surface of the earth. The points all have the same angle of elevation to the given satellite.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type . When you use instance method syntax to call this method, omit the first parameter. For more information, see
The returned points do not always form a perfect circle due to the Earth's equatorial bulge.
When the elevation angle of the points is specified as zero, the points form the satellite's "circle of visibility", which represents the area of the earth visible from the spacecraft.
