@Deprecated public class EstimatedTroposphericModel extends EstimatedModel implements DiscreteTroposphericModel
Deprecated.as of 12.1, replaced byEstimatedModel
An estimated tropospheric model. The tropospheric delay is computed according to the formula:δ = δh * mh + (δt - δh) * mw
With:
- δh: Tropospheric zenith hydro-static delay.
- δt: Tropospheric total zenith delay.
- mh: Hydro-static mapping function.
- mw: Wet mapping function.
The mapping functions mh(e) and mw(e) are computed thanks to a
EstimatedModel.model
initialized by the user. The user has the possibility to use several mapping function models for the computations: theGlobal Mapping Function
, or theNiell Mapping Function
The tropospheric zenith delay δh is computed empirically with a
tropospheric model
while the tropospheric total zenith delay δt is estimated as aParameterDriver
, hence the wet part is the difference between the two.
