use of COD sp3 files

[LucaFibbi]

To compile on my platform (Ubuntu 18.04) I had to modify the code like this:

diff --git a/QtMyTest.cpp b/QtMyTest.cpp

For use the program I had to modify the code like this:

Two subsequent sp3 files product of CODE centre have an epoch equal:
the last of first file and the first of second file. This produce an
problem in the program that it not find the correct epoch at boundary
of the files. To overcome the problem I made the following change:

                sp3file.close();
        }//for (int i = 0;i < SP3FileNames.length();i++)//Read multiple files at the end

I attach a test case with sp3 and clk CODE files.
test_data.zip

In the this test case the station geno have:
C 8 C2I L2I D2I S2I C7I L7I D7I S7I
observations for BeiDou costellation.
With the change from 2-7-6 to 2-6-7 in frequences selection the BeiDou observations
not are most used.

Dear LucaFibbi,
Thank you for your contribution to MG-APP. These questions are very important, thank you again.
Some observaion type mybe missing in BDS (SYS / # / OBS TYPES in RINEX). so, I use C1I replace C2I, C7I replace C6I.
Below is detaill code. I have updated MG-APP according to your question.

QReadFile::ProcesCLPos: 583

else if(epochSystem.SatType.contains("C", Qt::CaseInsensitive))
{// BDS 1 7 6 or 2
// "2" -> "6" -> "7" is for BDS-III
frqenceStr[0] = "2"; frqenceStr[1] = "6"; frqenceStr[2] = "7"; frqenceStr[3] = "1";
prioLen = 3;
prioArry[0] = "I"; prioArry[1] = "Q"; prioArry[2] = "X";
}

QReadFile::ProcesCLPos: 643
// if BDS
if(epochSystem.SatType.contains("C", Qt::CaseInsensitive))
{
QString C1i = "C" + frqenceStr[3] + prioArry[i], L1i = "L" + frqenceStr[3] + prioArry[i];
QString C2i = "C" + frqenceStr[2] + prioArry[i], L2i = "L" + frqenceStr[2] + prioArry[i];
int tempPos1 = -1, tempPos2 = -1;
// If C1I is missing, use C2I instead
// C1 L1
tempPos1 = obsType.indexOf(C1i);// find pos of C1P etc
tempPos2 = obsType.indexOf(L1i);// find pos of L1P etc
if(tempPos1 != -1 && tempPos2 != -1)
{
ObsTypePos.C1Type.append(C1i);
ObsTypePos.C1Pos.append(tempPos1);
// L1
ObsTypePos.L1Type.append(L1i);
ObsTypePos.L1Pos.append(tempPos2);
}
// If C6I is missing, use C7I instead
// C2 L2
tempPos1 = obsType.indexOf(C2i);// find pos of C2P etc
tempPos2 = obsType.indexOf(L2i);// find pos of L2P etc
if(tempPos1 != -1 && tempPos2 != -1)
{
ObsTypePos.C2Type.append(C2i);
ObsTypePos.C2Pos.append(tempPos1);
// L2
ObsTypePos.L2Type.append(L2i);
ObsTypePos.L2Pos.append(tempPos2);
}
}
