Abstract
The article presents results of verification of the kinematic measurements usefulness for precise real-time positioning RTK in the local reference system. These measurements allow for continuous RTK measurements in the event of temporary interruptions in radio or internet connections, which are the main reason for interruptions in RTK kinematic measurements and cause a decrease in the reliability and efficiency of this positioning method. Short interruptions communication are allowed during the loss of the key correction stream from the local RTK support network, so the global corrections obtained from the geostationary satellite are used. The aim of the article was to analyze the accuracy of measuring the position of moving objects. Practical conclusions were formulated according to the research subject, the presented mathematical models, the experiment and the analysis of the obtained results.
Highlights
The key point of precise positioning of the Global Navigation Satellite Syste) (GNSS) is the ability to mitigate all the potential source errors and interference in the system
The presented work has shown that use of the GNSS system integration can improve accuracy and reliable positioning of the GNSS navigation system
Since the Galileo system and the BeiDou satellite navigation system (BDS) have not yet reached full readiness, only the GPS systems and GLONASS were used in this article for research into the combination of multiple systems (Figures 3-6)
Summary
The key point of precise positioning of the Global Navigation Satellite Syste) (GNSS) is the ability to mitigate (reduce) all the potential source errors and interference in the system. All errors in the GNSS observations caused by signal propagation, the environment around the receiver and the equipment of the recipient, must be mitigated [1,2,3,4]. Limitation can be improved by modeling, estimating and creating individual combinations of station observations, as well as application of the differential mechanism of technique. Such errors of the analyzed observation are the subject of detailed considerations, included in the further part of this article
