Abstract

A more simple alternative for the solution of the second order design
problem of geodetic networks with respect to realization of the results has
been developed. One of the main poblemes, which can arise when solving
the SOD problem is that, the resulting weight vector may not reproduce a
cofactor matrix, which ensures the criteria requerements, in some parts of
the network, or all over the network. In this paper, this problem is treated
by modifying the resulting weight vector linearly, by its multiplication by a
scaler value . Numerical examples are given to illustrate its application.The
commercial "Matlab" program was used to solve the case studies
