How Radio Signals Were Used to Track Vehicles Before GPS

How feasible was the tracking technology depicted in 1960s spy movies?


I am curious about the realism of the scenes where the protagonists attach a small device to the antagonists' vehicle and then track its location on a map. This was before the advent of GPS, so what kind of mechanism could have enabled such tracking? Could it have been based on radio signals that needed to be triangulated by multiple receivers? How accurate would the location estimation have been?

The tracking technology in 1960s spy movies, while imaginative, likely relied on rudimentary radio signal triangulation methods, which could provide rough location estimates but lacked the precision and reliability of modern GPS systems. retro bowl college
