 abstract={The paper presents a suggestion of modification of Otrebski' s theorem for some special structures of geodetic networks. The modification leads to forming up the conditional equation system with unknowns. A new parameter as a global criterion of evaluation of the quality of the networks characterized by an inhomogenous observation system, has been introduced as well.},
