    ViennaOneModel

    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.

      • 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 satellite
        point - station location
        weather - weather parameters
        date - current date
        Returns:
        a two components array containing the hydrostatic and wet mapping functions.

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