All Implemented Interfaces:

IStelaSolarActivity, Serializable

public class StelaLOSConstantSolarActivity
extends AbstractStelaSolarActivity

Mean constant model of solar activity. This solar activity uses calculated constant F107 depending on the orbit and the ballistic coefficient (see User guide for more information). This computation is performed using the method updateF107(StelaSpaceObject, SpacecraftState). Resulting value is stored in losF107.

Since:

4.16
