The quality of a geodetic network is concerned with the precision and the reliability of the coordinates. The paper reviews various measures for precision and reliability which are related to the specification of the functional use of the network. The difficulties in using a criterion, which is not invariant with respect to S-transformations, are indicated. The use of a criterion matrix is outlined.

The sensitivity of a network for checking special hypotheses is discussed.
