Class DummyMappingFunction

java.lang.Object

org.orekit.models.earth.troposphere.DummyMappingFunction

All Implemented Interfaces:

TroposphereMappingFunction

public class DummyMappingFunction
extends Object
implements TroposphereMappingFunction

Dummy mapping function.

This mapping function just uses 1.0 as constant mapping factors, which implies the slanted tropospheric delays are equal to the zenith delays. This is mainly useful when only zenith delays are needed.

Method Details

mappingFactors

public double[] mappingFactors(TrackingCoordinates trackingCoordinates,
 GeodeticPoint point,
 AbsoluteDate date)

This method allows the computation of the hydrostatic and wet mapping functions. The resulting element is an array having the following form:

• double[0] = m_h(e) → hydrostatic mapping function
• double[1] = m_w(e) → wet mapping function

Specified by:

mappingFactors in interface TroposphereMappingFunction

Parameters:

trackingCoordinates - tracking coordinates of the satellite

point - station location

date - current date

Returns:

a two components array containing the hydrostatic and wet mapping functions.

mappingFactors

public <T extends CalculusFieldElement<T>> T[] mappingFactors(FieldTrackingCoordinates<T> trackingCoordinates,
 FieldGeodeticPoint<T> point,
 FieldAbsoluteDate<T> date)

This method allows the computation of the hydrostatic and wet mapping functions. The resulting element is an array having the following form:

• T[0] = m_h(e) → hydrostatic mapping function
• T[1] = m_w(e) → wet mapping function

Specified by:

Type Parameters:

T - type of the elements

Parameters:

trackingCoordinates - tracking coordinates of the satellite

point - station location

date - current date

Returns:

a two components array containing the hydrostatic and wet mapping functions.
