public interface DiscreteTroposphericModel extends MappingFunction
Defines a tropospheric model, used to calculate the path delay imposed to electro-magnetic signals between an orbital satellite and a ground station.Models that implement this interface split the delay into hydrostatic and non-hydrostatic part:
δ = δh + δnh
With:- δh = hydrostatic delay
- δnh = non-hydrostatic (or wet) delay

- Parameters:
height
- the height of the station in m above sea level.parameters
- tropospheric model parameters.date
- current date- Returns:
- a two components array containing the zenith hydrostatic and wet delays.
