20.500.12556/RUL-73031 Analiza natančnosti in uporabnosti enofrekvenčnih GNSS-senzorjev diplomska naloga Accuracy and Applicability of Single-Frequency GNSS Sensors Ena osnovnih nalog geodezije je natančna določitev položaja (koordinat) v terestričnih koordinatnih sistemih. Zaradi hitrega tehnološkega napredka in razvoja satelitske geodezije lahko danes to nalogo izvajajo tudi uporabniki, ki ne poznajo konceptov satelitskega pozicioniranja. A ne zanima nas le položaj, zelo pomembna je tudi položajna kakovost. Trenutno niti GNSS-sistemi niti GNSS-sprejemniki ne zagotavljajo ustreznih podatkov o kakovosti pridobljenega položaja. Osrednja motivacija za nastanek naloge je ravno pomanjkanje teh podatkov. V diplomski nalogi so predstavljeni osnovni koncepti kodnih opazovanj GNSS. Opisani so sistemi in podsistemi GNSS, ki se jih poslužujejo enofrekvenčni sprejemniki. Pripravili smo dva preizkusa položajne kakovosti: statični in kinematični način. Oba smo izvedli v »skoraj popolnih« in zahtevnih razmerah za sprejem satelitskega signala. One of the basic tasks of geodesy is determination of accurate position (coordinates) in terrestrial coordinate systems. Due to a rapid technological and satellite geodesy development, also a common user nowadays is able to find out his position accurately, despite not being familiar with concepts of satellite aided positioning. Besides position itself, the position quality is of great importance. We may stress that nor GNSS nor GNSS-receivers do not provide relevant information regarding quality of acquired position. Absence of relevant information about positioning quality was the motivation for our testing of few GNSS sensors, available in present-day single-frequency GNSS receivers. GNSS and supporting systems, used by single-frequency GNSS receivers are also described. Two tests were set up for testing position quality: static and kinematic mode. Both were conducted in »near perfect« and difficult conditions. for the reception of satellite signal. geodezija diplomska naloga UNI GIG natančnost uporabnost GNSS enofrekvenčni sprejemnik ročni sprejemnik graduation thesis geodesy accuracy applicability GNSS single-frequency receiver hand-held receiver true false false [K.
