Abstract
Free networks only, i.e. networks for which the datum has to be defined, will be considered in the following. Thus, the property of these networks, especially the dependency of the covariance matrix of the estimated coordinates on the choice of the datum will be reviewed first. Estimable coordinates for the free nets will be obtained by means of projected parameters and it will be shown that these projections also give the transformations between different datums.
