Abstract
There is described a method of determining a position of a pipeline inspection gauge (PIG) in a fluid conduit. While the PIG is moving through the fluid conduit, one or more sensors positioned along the fluid conduit are used to detect one or more signals. Parameter data is extracted from the detected one or more signals. The parameter data includes one or more parameters of the detected one or more signals as a function of time and position along the fluid conduit. PIG movement data indicative of a position of the PIG in the fluid conduit as a function of time is generated using the parameter data.
