Proceed to the building northeast of Orlov Military Base and go up to the second floor to find a map on the wall.
You'll find 4 pictures posted beside the map itself showing the locations of the Calibration Data USBs around Urzikstan. Compare these locations with your own Tac-Map and head over there once you've confirmed a location.
Keep in mind that the locations of the USB sticks are random and will change each time you hop into a new game session.
Activate the console at the bottom of the Tower to receive a Calibration Data USB. Activating the console will take some time, so be sure you've cleared the area of zombies or have a squadmate watching your back.
It's important to note that you won't be able to exfil with these Calibration Data USBs and you'll lose all of them should you die in-game. However, if you have the Tombstone perk, you can retrieve them again in the next game!
NOTE: This is a list of all possible Calibration Data USB locations. The 4 locations that spawn during your Zombies match will depend on what you find when you visit the Orlov Military Base.
