The comedic timing on some of this video is impeccable.
It can be done in real-time and really needs 3 towers that have accurate time (GSM towers to my knowledge do use GPS derived accurate time). For this rather than direction/signal strength it uses the minute difference in arrival time for a signal between towers and works like an inverse GPS to calculate position.
Just a being pedantic and a stickler for detail. I’d expect modern tracking to use trilateration/multilateration.
