Detailed Description

This class eases computing Pdelta 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;
   ComputePdelta getPdelta;

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

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

When used with the ">>" operator, this class returns the same incoming data structure with the Pdelta 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.

Sometimes, the Rinex observations file does not have P1, but provides C1 instead. In such cases, you must use the useC1() method.

All observations are in meters.

See also:

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