Sažetak
GNSS has limitations or cannot be applied in specific environments with poor geometry like city streets, tunnels, bridges, or in indoor environment in general. To overcome these difficulties many researches have supplemented GNSS with pseudolites which also have their own limitations. Locata Corporation developed Locata system which relies on the network of ground-based, time synchronised transceivers (LocataLites) that transmit positioning signals. Locata system has patented wireless technology for time synchronization between LocataLites-TimeLoc. Within the project “Wearable outdoor augmented reality system for enrichment of touristic content” Locata system was implemented in the City of Čakovec, Croatia. Installed Locata equipment consists of six LocataLite transceivers and two Locata receivers with corresponding antennas. Prior to establishing Locata network (LocataNet) in the field, different network configurations were simulated to achieve best possible accuracy in horizontal and vertical direction. As optimal configuration, rectangular shape 100 long and 50 meters wide was chosen and established in the field. Established LocataNet, measurements were conducted and analysed to get insight into the precision and accuracy of absolute and relative positioning. After this, measurements of different long and short term simulated displacements were and will be conducted in the established LocataNet. The goal of research is to get the insight into the possibilities of the Locata positioning system to determine both long and short term displacements of constructions. Future research will include establishment of LocataNet on the constructions like bridges and dams to determine construction displacements and comparison of Locata positioning system with other geodetic measurement systems and methods.
