public class ViennaOne extends AbstractVienna
The Vienna 1 tropospheric delay model for radio techniques. The Vienna model data are given with a time interval of 6 hours as well as on a global 2.5° * 2.0° grid. This version considered the height correction for the hydrostatic part developed by Niell, 1996.- Since:

mappingFactors
public double[] mappingFactors(TrackingCoordinates trackingCoordinates, GeodeticPoint point, PressureTemperatureHumidity weather, 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] = mh(e) → hydrostatic mapping function
- double[1] = mw(e) → wet mapping function
- Parameters:
trackingCoordinates
- tracking coordinates of the satellitepoint
- station locationweather
- weather parametersdate
- current date- Returns:
- a two components array containing the hydrostatic and wet mapping functions.
