Original Abstract

V článku jsou popsány odhady přesnosti polohy založené na zákonu šíření pravých a středních chyb.

English abstract

In the paper the estimates of position accuracy are given which are based on consistent and subsequent use of the true and mean square errors propagation laws. Firstly the covariance matrices MU of the simple functions FX , FY, FZ of measured quantities Li, e.g. of the coordinates X, Y, Z of termined points U, are computed for each of the two measuring epochs compared. In following phase the acuuracy of the polar coordinates s, á of the monitored points displacements vectors s are derived. Reliability of the vectors depends upon proper relations of the introduced weights pi of the measured quantities Li , upon degrees of freedom in the horizontal network parametric adjustment, upon stableness of the given points (ties) K, and upon relative size of the residual systematic errors ci of measured quantities Li in relation to the respective random errors.
