Today, just by activating a button on the display panel of a total station, one can measure horizontal and vertical angles or calculate distances and coordinates of points. For this reason, it has become necessary to improve the check of a total station in order to respond to its contemporary way of use. The aim of this research is to create a new method for checking total stations using only one check-field, in a different way of the today's standards. The basic principle, of the comparison of an instrument's measurements to those of another instrument with higher accuracy, is implemented into a mathematical model such as the adjustment of an indoor geodetic network. Thus, the check of the proper function of a total station is applied. An a-priori calculation of σ o of the network's adjustment can be calculated by modeling the uncertainties using statistical methods as the random number generators by means of the Monte Carlo method. The prospective σ o can then be compared to the a-posteriori σ o provided by the adjustment of the measurements which are carried out by using the total station under check.Key words: Single control network, geodetic network, Monte Carlo techniques.

The elements of the matrix are formed as the difference between the calculated horizontal angles by using the reference coordinates and the l 1 measured horizontal angles by the TS ch δl V The matrix (1 × l 2 ). The elements of the matrix are formed as the difference between the calculated vertical angles by using the reference coordinates and the l 2 measured vertical angles by the TS ch δl D The matrix(1 × l 3 ).
