gnsstk::DCBDataReader Class Reference

Detailed Description

This is a class to read and DCB(Differences of Code Biases) data file from CODE.

You can find DCB data at:

ftp.unibe.ch/aiub/BSWUSER50/ORB - daily P1-P2 ftp.unibe.ch/aiub/CODE - monthly P1-P2 and P1-C1

You should use different objects to load different DCB files. A typical way to use these classes follows:

   // Declare some Antenna objects
DCBDataReader dcbP1P2("P1P21002_ALL.DCB");
DCBDataReader dcbP1C1("P1C11002.DCB");
 
double p1p2Sat1 = dcbP1P2.getDCB(1, SatelliteSystem::GPS);
double p1c1Sat1 = dcbP1C1.getDCB(1, SatelliteSystem::GPS);
 
double p1p2ALGO = dcbP1P2.getDCB("ALGO");
