Detailed Description

template<class Model>
class gnsstk::TropCorrector< Model >

Provide a means for estimating the pseudorange delay due to tropospheric conditions. To use it, instantiate one of the typedefs, then call one of either setDefaultWx() or loadFile() (the most recently called will be used to set the model's weather data). At that point, the getCorr() methods may be used.

gnsstk::GlobalTropCorrector trop;
double corr;
if (!trop.loadFile("arlm2000.15m"))
   return false;
if (!trop.getCorr(stnPos, svPos, sat, obsID, when, nav, corr))
   return false;
cout << "trop delay: " << corr << " m" << endl;

Note: The NBTropModel::setWeather() approach (calling with no arguments so that the data may be modeled using latitude and time) can be used by simply not calling setDefaultWx() or loadFile() either one. This approach is unique to NBTropModel. All other models will indicate an error condition if no weather data is loaded.

Parameters

Model The tropospheric model class, which is expected to be derived from the TropModel class. Since there is a relatively limited number of these, there are typedefs for each of the existing TropModel classes.
