FISSURE is an open-source RF framework that supports both operational deployments and research and education.
- For operators, it provides a rapidly deployable toolkit for signal detection, classification, protocol discovery, fuzzing, vulnerability analysis, and real-time integration with TAK.
- For educators and researchers, it lowers the barrier to entry for SDR and reverse engineering, offering a shared environment for learning, experimentation, and publishing new methods.
FISSURE streamlines complex SDR workflows by centralizing software, libraries, and reference material into one consistent framework that runs on desktops, laptops, single-board computers, and ruggedized systems, or scales to distributed tactical nodes networked in the field.

Dual-Use Relevance
- Operators: Detect, geolocate, and respond to RF activity in the field
- Researchers: Test new algorithms, automation, and AI and ML approaches
- Educators: Teach SDR, DSP, RF security, real-time processing, and reverse engineering in the classroom
- Students and Hobbyists: Explore SDR workflows and learn about technology without steep setup overhead
Roadmap and Development
FISSURE’s roadmap evolves with customer demand and community feedback.
For the most up-to-date view, explore the interactive roadmap:
Current Priorities
- Plugin Ecosystem: Redefining plugin boundaries and execution, developing a standalone plugin editor, converting existing flow graph libraries into plugins, and improving how plugins are deployed on sensor nodes and loaded into TAK.
- TAK Integration: Creating a WinTAK application, enhancing the bridge between TAK and FISSURE’s hub, enabling plugin/action selection directly in TAK, and strengthening alerting and coordination features.
- Installer & Packaging: Breaking out installers by operating system, improving error logging, delivering prebuilt ISOs and VM images for popular platforms, and exploring Docker and Apptainer for deployable FISSURE components.
- Tactical Node Orchestration: Expanding plugin support on nodes, integrating new sensor types, laying the foundation for multi-node coordination, and improving artifact recording/synchronization and networking resilience.
- Electronic Support / Monitoring: Extending direction-finding and monitoring capabilities, with emphasis on practical electronic support workflows.

News
Updated Node Networking Nodes automatically connect to the HIPRFISR/hub over IP or Meshtastic and show up in WinTAK.
Headless HIPRFISR/Hub The HIPRFISR can be run without the Dashboard using the fissure-hiprfisr command with "auto_connect_hiprfisr=false". A remote Dashboard can then be connected to the HIPRFISR over an IP network from the status bar.
Apptainer Containerization Run FISSURE inside a lightweight Apptainer container for consistent, portable deployments with full GUI and hardware access.
Command Line Installer Quickly install FISSURE and its dependencies using a streamlined command line interface with mode selection and automation options.
