Constructor Details

AbstractChaoMappingFunction

protected AbstractChaoMappingFunction(double ad,
 double bd,
 double aw,
 double bw)

Builds a new instance.

Parameters:

ad - first coefficient for hydrostatic (dry) component

bd - second coefficient for hydrostatic (dry) component

aw - first coefficient for wet component

bw - second coefficient for wet component

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:

mappingFactors in interface TroposphereMappingFunction

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.
