  W pracy przedstawiono przebieg dwóch kampanii pomiarów satelitarnych, zrealizowanych w celu oceny efektów regulacji osi toru kolejowego. Pierwsza kampania pomiarowa miała na celu identyfikację stanu istniejącego, druga zaś − określenie ukształtowania toru po przeprowadzonej regulacji jego osi. Ponieważ projekt regulacji został wykonany za pomocą tradycyjnych metod geodezyjnych, stworzyło to możliwość oceny poprawności tychże metod...

  - Zeszyty Naukowo-Techniczne Stowarzyszenia Inżynierów i Techników Komunikacji w Krakowie. Seria: Materiały Konferencyjne - Year 2013

  W artykule podjęto kwestię skuteczności wykorzystania wykresu strzałek poziomych do określania rzeczywistego kształtu toru kolejowego. Temat ten jest o tyle istotny, że przez dziesiątki lat wykres ten był wykorzystywany w metodach regulacji osi toru i dopiero od stosunkowo niedawna stracił swoje kluczowe znaczenie. Najnowsze publikacje o charakterze naukowym wskazują jednak, że poruszany temat nie został jeszcze wyczerpany i nadal...
