Detailed Description

This class eases computing Ldelta combination for GNSS data structures.

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");

   gnssRinex gRin;
   ComputeLdelta getLdelta;

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

The "ComputeLdelta" object will visit every satellite in the GNSS data structure that is "gRin" and will try to compute its Ldelta combination.

When used with the ">>" operator, this class returns the same incoming data structure with the Ldelta inserted along their corresponding satellites. Be warned that if a given satellite does not have the observations required, it will be summarily deleted from the data structure.

All observations are in meters.

See also:

ComputeLinear.hpp and LinearCombinations.hpp for a different approach to the same task.
