They have drones and satellites they routinely fly over large cities. Used to be they could track cars and by extention people. I would be surprised if they don’t have mostly accurate maps of here any given person is at any given time.
They don’t need satellites. They have Automated License Plate Recognition Systems by evil companies like flock that have laughably dystopian stated goals like “creating a crime free world” by tracking every vehicle everywhere and creating a national searchable database of ping points that they passed. And they’re expanding wildly, explosively year over year in the number of these they have deployed.
Even just looking at what’s available in the commercial sector, the dystopian tracking tech is wild. 3D reconstruction modelling of precise movement, number of people in a room, and pathtracing precise to the foot (way better than GPS) just based on disruption to WiFi signals in a room or area alone. No phone or connected device actually on you needed.
The limitation is computational cost and the amount of time and effort needed to focus on it. But you better believe that the NSA for example can do this sort of thing with a specific target and a starting point with good conditions for it to work.
