USAGE OF HEURISTIC ALGORITHM FOR OPTIMIZATION OF PRECISE GNSS RTK MEASUREMENT
Original language description
The contribution deals with formulation of technology for precise positioning with use of global navigation satellite systems (GNSS) in railway engineering during construction and maintenance of railway line and its spatial position. The technology was developed for Railway Infrastructure Administration, state organization (SŽDC) in order to solve automated maintenance of spatial position of railway line on territory of the Czech Republic. There is a dense network of railways length about 9,600 km covering an area of about 68,300 km2. The paper describes basic context of GNSS technology usage for railway precise positioning, and proposition of algorithm for field GNSS measurement optimization with use of the shortest Hamilton's path in graph method with additional conditions in nodes. The core of the algorithm is a dynamic data structure which is based on events list. The optimization of field measurement solves its time demands and economic effectiveness. The technology enables precise position determination with absolute difference limit from 10 to 15 mm within GNSS CZEPOS permanent network on territory of the Czech Republic. The algorithm was realized in Borland Delphi and verified in field on selected railway lines.
