Detailed Description

This class defines handy linear combinations of GDS data.

This class is meant to be used with the GNSS data structures (GDS) objects found in "DataStructures" class, and it is intended to be coupled with class ComputeLinear.hpp.

A typical way to use this class follows:

      // Define a LinearCombinations object
   LinearCombinations comb;

      // Object to compute linear combinations of data
      // Linear combinations will be computed in a FIFO basis
   ComputeLinear linear;

      // Add a linear combination to compute PC combination using C1
   linear.addLinear(comb.pcCombWithC1);

      // Add a linear combination to compute prefit residual using PC
   linear.addLinear(comb.pcPrefit);


      // Load observation data
   RinexObsStream rin("ebre0300.02o");

      // Loads precise ephemeris object with file data
   SP3EphemerisStore SP3EphList;
   SP3EphList.loadFile("igs11513.sp3");

      // Sets nominal position of receiver
   Position nominalPos(4833520.3800, 41536.8300, 4147461.2800);

      // Declare a MOPSTropModel object, setting the defaults
   MOPSTropModel mopsTM( nominalPos.getAltitude(),
                         nominalPos.getGeodeticLatitude(), 30);

      // Object to compute the tropospheric data
   ComputeTropModel computeTropo(mopsTM);

      // Declare a basic modeler
   BasicModel basic(nominalPos, SP3EphList);

   gnssRinex gRin;

   while(rin >> gRin)
   {

      gRin >> basic >> computeTropo >> linear;

         // Dump results
      gRin.body.dump(cout,1);

   }
