Detailed Description

This is a class to compute the main values related to a given GNSS tropospheric model.

This class is intended to be used with GNSS Data Structures (GDS). It is a more modular alternative to classes such as ModelObs and ModelObsFixedStation.

A typical way to use this class follows:

      // Input observation file stream
   RinexObsStream rin("ebre0300.02o");

      // Define the tropospheric model to be used
   NeillTropModel neillTM;
   neillTM.setReceiverLatitude(lat);
   neillTM.setReceiverHeight(height);
   neillTM.setDayOfYear(doy);

      // Now, create the ComputeTropModel object
   ComputeTropModel computeTropo(neillTM);

   gnssRinex gRin;  // GNSS data structure for fixed station data

   while(rin >> gRin)
   {
         // Apply the tropospheric model on the GDS
      gRin >> computeTropo;
   }

The "ComputeTropModel" object will visit every satellite in the GNSS data structure that is "gRin" and will try to compute the main values of the corresponding tropospheric model: Total tropospheric slant correction, dry vertical delay, wet vertical delay, dry mapping function value and wet mapping function value.

When used with the ">>" operator, this class returns the same incoming data structure with the extra data inserted along their corresponding satellites.

Be warned that if a given satellite does not have the information needed (mainly elevation), it will be summarily deleted from the data structure. This also implies that if you try to use a "ComputeTropModel" object without first defining the tropospheric model, then ALL satellites will be deleted.
