@Alexey Razumovsky, Attached is a report that I got from Web DPOS. Can anyone explain what the Cor. EN, Cor. EU and Cor. NU represent.

Thanks

Cor.EN, Cor.EU, Cor. NU are Site position correlations. For the report in latitude, longitude we print correlations in North, East, Up coordinate system.
Correlations are non diagonal elements of Site correlation matrix.
Gotten separately Site correlation matrix. has no practical sense.
Correlation matrixes has sense for new adjustment based on previously adjusted/reference Sites. Reference points comes in adjustment with coordinates and correleation matrixes.
