How (and why) does one track a pipeline? Asking for a friend.

Layman’s terms we run tools called smart pigs thru the line that measure wall thickness, weak spots etc. of the pipe. We track them by going out before the tool runs and survey Above Ground Markers (AGM’s) every mile and place a wooden stake painted pink above the pipeline.
After the tool is launched me and some coworkers track the tool as it flows with the product via a listening device called a geophone and a visual program on a laptop that detects the magnets on the tool or the 22Hz frequency of a transmitter on the tool.
We record the passages and send them out on a text chain with operations so we can maintain a average speed of the tool till it comes to the end of the survey.
