Purpose This paper aims to deal with the formulation of the technological principle for precise positioning using global navigation satellite systems (GNSS) in railway engineering during construction and maintenance of a railway line and its spatial position. Solution of optimal route is based on finding the shortest Hamiltonian path in the graph method with additional conditions in nodes. Design/methodology/approach The core of the algorithm is a dynamic data structure which is based on events list. The optimization of field measurement solves the time demands and brings economic effectiveness. Findings The technology enables to determine the precise position with absolute difference limit from 10 to 15 mm within GNSS CZEPOS permanent network in the territory of Czech Republic. Research limitations/implications Technology is the result of applied research. Practical implications This technology innovates the current procedure of geodetic control network determination used by Railway Infrastructure Administration (state organization) in Czech Republic. Originality/value The event means measurement at a given track point and time for a specified duration of observation. The algorithm was realized in Borland Delphi. The optimization of field measurement solves its time demands and increases economic effectiveness. The technology enables precise position determination with absolute difference limit from 10 to 15 mm within GNSS CZEPOS permanent network in the territory of Czech Republic. It has been verified in field selected electrified and non-electrified railway lines.

This paper presents results and remarks about the use of a global positioning system (GPS) geodetic network for the monitoring of surface deformations ongoing in the region of Bages, Catalonia (Spain). The area under investigation presents an extensive salt formation (2.100 km 2 ) known as 'Conca Potàsica'. The basin consists of a large block of potassium salts which were already used for extraction purposes in ancient times. Continuous underground and superficial mining from authorized private companies gave rise to a phenomena of subsidence in the past. This aggravated the existing natural subsidence caused by the dissolution of potassium and magnesium salts which affected many urban areas. By the second half of the twentieth century, deformations of about 1 m were recorded in this area. The GPS network consisting of 36 points distributed throughout the territory of Bages was firstly measured in December 2007, then a second survey took place in 2008. Results of this second campaign were compared with those of 2007 in order to detect surface deformations in the area of Bages. Statistical analysis of the position differences between the two epochs showed that significant displacements have occurred so far just for the sites actually located on the geologically unstable subareas of the 'Conca Potàsica'.
