Testování nízkonákladových přijímačů GNSS ve statickém režimu

Abstract

This bachelor thesis evaluates the positioning accuracy of low-cost u-blox GNSS receivers (the dual-frequency ZED-F9R and the triple-frequency ZED-X20P) in static mode across three locations, using the Trimble R10 geodetic receiver as a source of reference coordinates. Repeated six-hour measurements were conducted at all locations. Data processing using the static relative differential method (GPS+Galileo) demonstrated that the low-cost receivers achieved an agreement with the reference coordinates on the order of single centimeters across all 3D position components. Incorporating the BeiDou system into this processing method did not result in any significant differences. When employing the Precise Point Positioning method, the average agreement with the reference coordinates for both low-cost receivers remained at the single-centimeter level; however, discrepancies exceeding two decimeters were observed in certain cases.
