摘要本文介绍了Ubisense RTLS定位系统的精度调查结果和功能。进行了标定精度检验、坐标确定理论精度分析和现场条件下精度测量三方面的研究。采用不同几何星座的参考点（标签位置）对标定精度进行了测试。我们确定了接收机方向参数的变化和定位点坐标对选定参考点星座的扰动。对几种接收机空间位置及其方位进行了理论精度分析。它允许在考虑精度和可靠性的情况下指出有利和不利的测量区域。通过与精密测速计TCRP1201+测量坐标的对比，确定Ubisense系统的真实定位精度。所进行的实验结果和测试测量的精度分析以图形和图表的形式给出。
Abstract This paper presents the accuracy investigation results and functionality of Ubisense RTLS positioning system. Three kinds of studies were conducted: test of calibration accuracy, analysis of theoretical accuracy of the coordinates determination as well as accuracy measurements in field conditions. Test of calibration accuracy was made with several different geometric constellation of reference points (tag positions). We determined changes of orientation parameters of receivers and disturbance of positioning points coordinates against chosen reference points constellations. Analysis of theoretical accuracy was made for several receivers spatial positions and their orientations. It allowed to indicate favourable and unfavourable measurement area considering accuracy and reliability. Real positioning accuracy of the Ubisense system was determined by comparison with coordinates measured using precise tacheometer TCRP1201+. Results of conducted experiments and accuracy analysis of test measurement were presented in figures and diagrams.
