“…At other research centres, analogous studies were also undertaken to integrate tacheometric and GNSS surveys [ 26 ], with measurement support through the application of inertial navigation systems (INS) [ 27 , 28 ] or the application of mobile laser scanners [ 29 , 30 ]. In addition, studies were conducted to apply multisensor methods [ 31 , 32 , 33 , 34 , 35 , 36 ].…”

Satellite geodetic networks are commonly used in surveying tasks, but they can also be used in mobile surveys. Mobile satellite surveys can be used for trackage inventory, diagnostics and design. The combination of modern technological solutions with the adaptation of research methods known in other fields of science offers an opportunity to acquire highly accurate solutions for railway track inventory. This article presents the effects of work carried out using a mobile surveying platform on which Global Navigation Satellite System (GNSS) receivers were mounted. The satellite observations (surveys) obtained were aligned using one of the methods known from classical land surveying. The records obtained during the surveying campaign on a 246th km railway track section were subjected to alignment. This article provides a description of the surveying campaign necessary to obtain measurement data and a theoretical description of the method employed to align observation results as well as their visualisation.
