An open source framework for building positioning systems that fuses multiple positioning techniques and algorithms into a single data processing model.
What it is
OpenHPS is an open source framework for building hybrid positioning systems that helps developers fuse various positioning technologies and algorithms. The system offers a modular data processing framework with modules ranging from computer vision to common algorithms such as fingerprinting or data persistence of sampled data.
At its core, OpenHPS is a graph of connected nodes that process information, with three types of nodes: source nodes that generate new data frames from sensors, processing nodes that transform the data using positioning algorithms, and sink nodes that store or display results.
The framework supports 2D, 3D and geographical positioning, relative positioning such as distance or angle to landmarks, and common algorithms including trilateration, triangulation, fingerprinting and dead reckoning. It is extensible, allowing developers to add their own nodes, algorithms and data services, and modular so users can select only the modules needed for their use case.
The project is maintained and used by the Web and Information Systems Engineering Lab at the Vrije Universiteit Brussel.
What it is built with
- 2D, 3D and geographical positioning
- Relative positioning (distance or angle to landmarks)
- Common algorithms: trilateration, triangulation, fingerprinting, dead reckoning
- Computer vision through @openhps/opencv module
- Extensible with custom nodes and algorithms
- Modular architecture with optional components
- Runs in Node.js and browsers
- Protocol Buffers support for serialization

Questions from the bench
- What is OpenHPS?
- OpenHPS is an open source framework for building hybrid positioning systems that fuses multiple positioning techniques and algorithms into a single data processing model, allowing you to go from raw sensor data to a position for one or more objects.
- Do I need to know TypeScript to use OpenHPS?
- The OpenHPS examples are written in TypeScript, but the framework works fine in plain JavaScript. TypeScript simply gives you editor support and type safety.
- Do I need any hardware to try OpenHPS?
- No. The mouse example lets you build your first positioning model using nothing more than your mouse. Hardware-specific examples are available for devices such as smartphones, IMUs or RF beacons.
- Can OpenHPS run in the browser?
- Yes. OpenHPS can be loaded from a CDN and many modules provide browser builds.
- Where can I get help with OpenHPS?
- Open an issue on the relevant GitHub repository or contact the team at info@openhps.org.
