Complex processing of geodetic measurements

About Us

Prof. Martin Štroner, Ph.D.
Pavel Třasák, Ph.D.

In the long term we deal with an adjustment of geodetic measurements. Our specialty is the least squares adjustment extended by robust estimators enabling an automatic rejection of outlying measurements. Our unique knowledge is also an analysis of a prior and a posterior accuracy of the measurements and a complex exact processing of movement and deformation measurements. In addition to the data processing we focus on a highly accurate engineering surveying.

Beside the software development we also deal with a research of above topics, as can be seen below in an overview of selected publications.
