Positioning system for pig iron torpedoes. These are the cars which transport pig iron (molten material is obtained by reduction of iron ore) from the blast furnace to steel mills, where it becomes steel. SATRA indicates what position in the cycle the torpedo is in: Load the blast furnace, desulphurized, or in a position in the steelworks. The system consists of:
  1. Two transmitters in each car, combining ultrasound with IEEE 802.15.4, to allow for positioning.
  2. A receiver-finder, in every position that we want to know, which receives the signals.
  3. And a basic TCP / IP in each area for communication with higher levels of control of the mill.
