How to unlock the Orbital Obliteration achievement in Grand Theft Auto V - Definitive Guide
You can purchase the upgrade at the same time you purchase your Facility, or you can purchase it later by heading to the in-game Maze Bank Foreclosures website (accessible from the Travel & Transport section of the in-game web browser). Once on the site, you can click on the Facility you own, which will show you various upgrades which can be purchased for your Facility: select the Orbital Cannon Upgrade and purchase it for $900,000.
Next, head to the Orbital Cannon room in your Facility, and kill another player with the Orbital Cannon for the trophy. With each Orbital Cannon shot costing $500,000 (manual) or $750,000 (homing, i.e. automatic lock-on), you should make your shot count.
I highly recommend having a friend tell you where they are while in a Private Session and using the green arrow to locate them. Once you've located your friend, hold for 3 seconds to launch the missile at them. Once they have been smitten, the trophy will pop.
This achievement is best done in a private session with at least one other player.
Once you have purchased your Facility, you are given the option to furnish and upgrade the building with a variety of rooms and services. One of these upgrades is the Orbital Cannon, which costs $900,000. Purchase this upgrade and then visit the Facility.
Make your way to the Orbital Cannon room. It's located towards the back of the building, right across the Heist Briefing Room. Approach the table and interact with the menu by pressing . You will now be able to surveillance the entirety of Los Santos via a bird's eye view.
Coordinate with the other player in your game to find where on the map they are located (there should be a faint green box around them). Once you know their position, you can choose to fire a manual targeting shot for $500,000, or an automatic targeting shot for $750,000. Since they should be standing still, the cheaper option is more advisable. The achievement will unlock once you have killed the other player with the Cannon.
NOTE: There is a 48-minute cooldown on the Cannon. Additionally, other players cannot use your Cannon whatsoever; however, they are able to spectate your actions through the surveillance feed while you are operating it.
