Detailed Description

This class computes satellites weights based on URA Index.

This class is meant to be used with the GNSS data structures objects found in "DataStructures" class.

A typical way to use this class follows:

   RinexObsStream rin("ebre0300.02o");
   RinexNavStream rnavin("brdc0300.02n");
   RinexNavData rNavData;
   GPSEphemerisStore bceStore;
   while (rnavin >> rNavData) bceStore.addEphemeris(rNavData);
   bceStore.SearchPast();  // This is the default

      // Declare a GDS object
   gnssRinex gRin;

      // Create a 'ComputeIURAWeights' object
   ComputeIURAWeights iuraW(bceStore);

   while(rin >> gRin)
   {
      gRin >> iuraW;
   }

The "ComputeIURAWeights" object will visit every satellite in the GNSS data structure that is "gRin" and will try to compute its weight based on the corresponding IURA. For precise ephemeris, a fixed value of IURA = 0.1 m will be set, returning a weight of 100.

When used with the ">>" operator, this class returns the same incoming data structure with the weights inserted along their corresponding satellites. Be warned that if it is not possible to compute the weight for a given satellite, it will be summarily deleted from the data structure.
