Detailed Description

This class eases computing PC 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;
   ComputePC getPC;

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

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

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

Warning:

When using C1 instead of P1 to compute this combination, be aware that instrumental errors will NOT cancel, introducing a bias that must be taken into account by other means.
