Bluetooth tracker in a postcard and mailed to a warship exposed its location

It would have to be something like an AirTag or Tile, otherwise it would be pointless? The only reason these are useful is because of the vast amount of phones that will report the location of the bluetooth tracker. A $10 chinese version wouldn’t work so well.

It’s pretty hard to hide warships these days. Imagery satellites with resolution good enough to track a ship capture every location on earth several times a day.

These days Bluetooth chips can be tracked using satellites using Hubble Network satellites (www.hubble.com)
