ADOS is built in public repositories. You can read every line that runs on your drone, fix it, extend it and run it on the hardware you choose.

Repositories

The Ground Agent is not a separate repository. It is the agent installed with the ground_station profile. The agent’s MAVLink router is native Rust; its Python helpers use pymavlink. For how the code in each repository is laid out, see Project structure.

What GPLv3 means for you

You cannot release GPLv3 code under a closed licence or add restrictions beyond what GPLv3 allows.
GPLv3 does not prevent commercial use. You can sell drones running ADOS, and you can charge for support, customization and integration. You cannot close the source.

MIT: the MCP server

ADOS-MCP is under the MIT licence. You can use, modify and redistribute it, including in closed-source software, as long as you keep the copyright and licence notice.

CC0: documentation and hardware designs

This documentation and the ADOS hardware designs (schematics, PCB layouts, mechanical drawings, enclosures and printable accessories) are dedicated to the public domain under CC0 1.0 Universal. You can copy, modify, manufacture and sell them with no obligation to credit Altnautica or share your changes.

Running without Altnautica infrastructure

Mission Control works with no backend: connect over USB, plan, fly and configure with no account and no internet. The agent works with no cloud: the cloud relay is off until you turn it on. To run the cloud features on your own servers, see Self-hosting. Mission Control works alongside other MAVLink ground control stations on the same vehicle.

FAQ

Can I use ADOS commercially? Yes. GPLv3 allows commercial use. If you distribute modified versions, those must also be GPLv3. Can I ship ADOS in a product without releasing my source? If you distribute ADOS, modified or not, you must provide the corresponding source under GPLv3, including your modifications. Running ADOS as a hosted service without distributing it does not trigger that requirement under GPLv3. Can I use parts of ADOS in a non-GPL project? Not the GPLv3 parts: work based on GPLv3 code must also be GPLv3. The MCP server is MIT and has no such requirement. Who owns the copyright? The original authors, Altnautica and contributors. Contributors keep the copyright on their contributions and license them under the repository’s licence. There is no contributor licence agreement.
