Detailed Description

This is a class to compute the main values related to a given GNSS ionospheric 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");

      // Now, create the ComputeTropModel object
   ComputeIonoModel computeIono(nominalPosition);
   computeTropo.setIonosphereMap(ionexFile);

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

   while(rin >> gRin)
   {
         // Apply the ionoospheric model on the GDS
      gRin >> computeIono;
   }

The "ComputeIonoModel" object will visit every satellite in the GNSS data structure that is "gRin" and will try to compute the main values of the corresponding ionospheric model.

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.
