GNSS INVENTORY OF HISTORIC NARROW-GAUGE RAILWAY LINE IN KOSZALIN UNDER EXTREMELY UNFAVORABLE MEASUREMENTS CONDITIONS FROM THE POINT OF VIEW OF SATELLITE SIGNALS AVAILABILITY
Abstrakt
A team of academic researchers from the Gdańsk University of Technology, Gdynia Maritime University and the Polish Naval Academy have been working since 2009 on the methodology of using active GNSS geodetic networks for geodetic inventory of railways and on adapting this measurement technique for designing geometric layouts of railway and tram lines. Over the years, the team tested a variety of configurations of receivers and settings of active GNSS networks with the objective to upgrade the accuracy of defining position coordinates and the availability of accurate determinations. The applied optimization methods helped to increase the accuracy of appointed positions in real-time measurements from 3 cm (DRMS) in 2009 to 6 mm (DRMS) in 2014, thus opening the possibility of simultaneous study of deformation of the rails. The article presents the assumptions and technology of implementation of the research; it presents the measuring system, the course of the measurements and the results of the inventory of the narrow-gauge railway routes in Koszalin (section length - 18 km) completed in May 2014. In contrast to the previous realizations, the conditions for the implementation of these measurements were extremely adverse (foliage), from the viewpoint of receiving GNSS signals. The results obtained were compared with analogous measurements performed in other measurement campaigns delivered by the research team. The paper points out existing limitations to the research implementation and proposes possibilities of their partial elimination.
