org.orekit.models.earth.ionosphere.SingleLayerModelMappingFunction

All Implemented Interfaces:

IonosphericMappingFunction

public class SingleLayerModelMappingFunction
extends Object
implements IonosphericMappingFunction

Single Layer Model (SLM) ionospheric mapping function.

The SLM mapping function assumes a single ionospheric layer with a constant height for the computation of the mapping factor.
