Abstrakt: A fiber delay measurement and tracking system,which consists of low-cost, off-the-shelf instruments and components, and finds application in several areas, such as Telecommunications, Radar and Radio Astronomy, is presented and tested in an on-the-field realisticscenario. Through a comparison performed with a correspondent high-cost version of the same system, and thanks to an accurate, physical-model-based postprocessing procedure, a precision of 0.1 ps is estimated for the fiber delay over a monitored distance of around 100 m.
