Underground geodesy, been developed and implemented, related to the link between the surface and underground geodetic networks, the guiding control with accurate gyro traverses and the check of cross sections with photoprofiling or profile scanners. Instruments and methods are described by the authors and the results presented.

Enterprise Interoperability VIIIern instruments and observation methods it is presently possible to determine an azimuth with a standard deviation of 3″ to 6″ within less than one hour. The principles of non-rotating optical gyroscopes are presented and their potential as alternatives to conventional instruments is discussed.

Accuracy problems when combining terrestrial and satellite observations,s affected by a number of network external influences. The first task can be overcome by the technique of estimating variance components of the individual observation groups, the second one can be handled by applying S-transofrmations to covariance matrices. The paper deals with problems of the hybrid stochastic model. Examples are given.
