OpenJAUS 4.0 is a C++ Software Development Kit (SDK) based on the latest JAUS standards. You can use the OpenJAUS middleware on your unmanned systems. It gives you the ability to standardize your software in order to make it interoperable with other SAE JAUS based systems.

OpenJAUS is designed for software developers that want to use JAUS without needing to know the low-level details of the standard itself. With OpenJAUS, you have direct access to the C++ library source code, so you can see and control what is running on your system.

• A clear and simple C++ API
• A completely open codebase. You can see all of the code and modify it to your needs.
• Compliance with the published JAUS standards
• JAUS Core, Mobility, Environment Sensing, and Manipulator services and message sets
• Customizable composition of JAUS services
• Simplified state machine architecture
• JAUS TCP and UDP message transport implementations
• Runs natively in Windows and Linux
• Dynamic configuration and discovery of JAUS components
• Event service message engine

OpenJAUS 4.0 is supported under a two different license types. For academic research or personal use a free license is available, and must be applied for online with our Free License Request Form. For commercial, government, or customer funded academic projects, users must purchase one or more commercial developers' licenses. You must purchase a separate licene for each person developing software with OpenJAUS 4.0. You can read an example OpenJAUS commercial license agreement here. With both the free and commercial license you have access to read or modify all of the OpenJAUS source code.

The commercial license enables development of systems with OpenJAUS that may be sold, distributed, or demonstrated to paying customers. Additionally, modifications or customizations to the OpenJAUS code under this license may be owned and kept proprietary by the licensee organization. The purchased license also includes more direct support.

When you purchase a commercial developers' license, you automatically get OpenJAUS 4.0 support for 1 year. Support for the SDK includes:

• Access to OpenJAUS code repositories with all improvements and upgrades that are continually made available to you for no additional charge.
• Up to 16 hours of direct technical support for each developer’s license. This will be made available through email or phone. Additional support can be purchased if necessary.
• User’s guide and API documentation will be available online and is free to the public.
• You may renew your support annually at a reduced cost. This allows you to continually upgrade your OpenJAUS code to our latest versions.
