Install POSIM

POSIM (Platform for Ocean Simulation) uses ROS 2 Lyrical and Gazebo Jetty. Choose one installation route below, then run the POSIM Quickstart. All required installation instructions are maintained in this Wiki.

Start here

• Use the tested Docker candidate: POSIM Docker Guide. Select ARM64 or AMD64 and pin the image digest.
• Develop on Ubuntu 26.04: POSIM Native Installation. Build IOES-Lab/POSIM on main with ROS 2 Lyrical and Gazebo Jetty.
• Run scenes and check output: POSIM Quickstart & Backend Support.
• Check hardware/backend limitations: POSIM System Requirements and POSIM Multibeam Sonar — CUDA & WGPU.

Names retained for compatibility

The repository and product are POSIM. ROS packages (dave_demos, dave_worlds, etc.), launch files and model names remain dave_*. The native checkout stays at ~/posim_ws/src/dave because the dependency manifest uses that key. Published containers retain their existing workspace paths; follow the Docker guide rather than replacing every occurrence of dave with posim.

Candidate versus release

The published validation-pr5-abad9d70-* images are test candidates. PR #5 remains unmerged, and they are not a main/1.0 release. WGPU and WAM-V work are tracked in separate open PRs. Do not use an unverified latest tag in place of the documented digest.
