Sažetak
GNSS has limitations or cannot be applied in specific environments with poor geometry likecity streets, tunnels, bridges, quarries, mines, ports or in indoor environment in general. In 2003Locata Corporation from Australia began with the development of a new, completelyindependent technology called Locata, which was designed to overcome the limitations ofGNSS. It can be combined with GNSS, or can be used as an independent measuring system, where the GNSS limitations are the biggest. Within the project “Wearable outdoor augmentedreality system for enrichment of touristic content” for the first time one Locata system wasimplemented in Croatia. Established LocataNet consists of six LocataLites and two Locatareceivers. Before establishing LocataNet it was necessary to simulate different networkconfigurations to get insight into geometry influence on positioning accuracy, i.e. the dilutionof precision (DOP) values inside LocataNet. The most demanding task was to achievereasonable VDOP values (i.e. to get largest possible area with VDOP values below 3). In thesimplest way, we could have made configuration of all LocataLites set on the ground and withapproximately same height which would lead up to high VDOP values inside LocataNet.Because of that, we decided to do optimal configuration with rectangular shape 100 meters longand 50 meters wide with two LocataLites in the middle of longer rectangular lines set up higherthan the others (12 meters above ground, compared to others that are set to 4 meters aboveground). This LocataNet was established in the field with permanent installation of antennas onstable concrete- steel pillars. In this paper, the basic theory behind calculating DOP values willbe given as well as results of simulating different LocataNet configurations and comparisons ofsimulation results with gathered data in the field.
