Abstract: This invention relates to a system and a method of positioning along the length of a cable. The positioning system (100) comprises the radiating cable (110), and also GNSS generator (120) generating the first and second GNSS signals, first injection module (131) to inject the first GNSS signals into a first end of the cable, and second injection module to inject the second GNSS signals into the second end of the cable. The first (second) GNSS signals are defined as signals that would be received at a point located at a first (second) virtual end of the cable, in an open sky configuration, from a first (second) set of satellites visible in a first (second) visibility cone.
