I mentioned the rover navigation system. This was an ingenious system on the rover which, from wheel rotations and turning data, calculated the distance and direction (bearing) back to the LM. But the data was not transmitted to Earth, it was displayed to the crew on the rover. Every now and then they read out the values:

143:54:03 Irwin: Okay, Joe; here's some readings... [bearing to LM] 343, [distance driven] 06.5, [range to LM] 05.0...

How different it will be next time! #Apollo
