mappingFactors
public double[] mappingFactors(TrackingCoordinates trackingCoordinates, GeodeticPoint point, PressureTemperatureHumidity weather, AbsoluteDate date)
With the Mendes Pavlis tropospheric model, the mapping function is not split into hydrostatic and wet component.Therefore, the two components of the resulting array are equals.
- double[0] = m(e) → total mapping function
- double[1] = m(e) → total mapping function
The total delay will thus be computed as:
δ = Dhz * m(e) + Dwz * m(e)
δ = (Dhz + Dwz) * m(e) = δz * m(e)- Specified by:
mappingFactors
in interfaceTroposphereMappingFunction
- 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.
