This thesis investigates the applicability of ultra-wideband (UWB) technology for local positioning, with an emphasis on the use of DW3110 integrated circuit. Different methods for distance measurement using UWB technology were analyzed, and a mathematical model for solving trilateration and multilateration problems was developed. Based on defined functional requirements and architecture, a prototype of a local positioning system was implemented, using development modules with DW3110 integrated circuit. A custom communication protocol and an algorithm for automatic determination of stationary node arrangement were developed, enabling network autocalibration for cases where their initial positions are unknown. A demonstration system for realtime mobile node tracking was implemented, and experimental evaluation under various operating conditions provided an estimate of measurement uncertainty, confirming the functionality and practical applicability of the developed solution.
U ovom radu istražene su mogućnosti primjene ultraširokopojasne tehnologije (UWB) za lokalno pozicioniranje, s naglaskom na korištenje integriranog sklopa DW3110. Analizirane su metode mjerenja udaljenosti primjenom UWB tehnologije teje razvijen matematički model za rješavanje problema trilateracije i multilateracije. Na temelju definiranih funkcionalnih zahtjeva i arhitekture, realiziran je prototip sustava za lokalno pozicioniranje, zasnovan na odabranim razvojnim modulima s integriranim DW3110 sklopom. Razvijen je komunikacijski protokol i algoritam za automatsko određivanje rasporeda stacionarnih čvorova, čime je omogućuna autokalibracija mreže u slučajevima kada njihove početne pozicije nisu poznate. Implementiran je demonstracijski sustav za praćenje mobilnog čvora u stvarnom vremenu, a eksperimentalnom evaluacijom u različitim uvjetima rada utvrđene su granica mjernih pogrešaka te potvrđena funkcionalnost i praktična primjenjivost razvijenog rješenja.
