First Order Design: Optimization of the Configuration of a Network by Introducing Small Position Chpecially 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

Second Order Design, point 10; as observations three distances from or to the fixed points 1, 2 and 3 are planned. The accuracy postulation is given by a circle with the radius 1 cm as error ellipse. This postulation is represented by the identity matrix as criterion matrix.and a standard deviation of the weight unit σ

Optimization Problems in Geodetic Networks with Signals,hysical sciences, geodesy being one of them, the relative simplicity of the considered part of the physical world allows the construction of models, i.e., creations of the human mind which with the help of the language of mathematics are more or less valid images of the relevant phaenomena in the re

Continuous Networks I,ond order. The method of constrained least- squares leads to differential equations up to fourth order, to characteristic boundary values and constraints according to the datum choice. Here only onedimensional networks on a line and on a circle are discussed. Their characteristic (modified) Green fu
