Constructor Details

ITURP834MappingFunction

public ITURP834MappingFunction(TimeScale utc)

Simple constructor.

Parameters:

utc - UTC time scale

Method Details

mappingFactors

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

Description copied from interface: TroposphereMappingFunction

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,

Type Parameters:

T - type of the elements

Parameters:

trackingCoordinates - tracking coordinates of the satellite
