Method Summary

Modifier and Type	Method and Description
double[]	mappingFactors(double elevation, GeodeticPoint point, AbsoluteDate date) This method allows the computation of the hydrostatic and wet mapping functions.
<T extends CalculusFieldElement<T>> T[]	mappingFactors(T elevation, FieldGeodeticPoint<T> point, FieldAbsoluteDate<T> date) This method allows the computation of the hydrostatic and wet mapping functions.

Method Detail

mappingFactors

double[] mappingFactors(double elevation,
                        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

Parameters:

elevation - the elevation of the satellite, in radians

point - station location

date - current date

Returns:

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