Sub-millimeter position and orientation tracking for robotics, industrial automation and metrology, indoors and in direct sunlight.
Enpose’s tracking technology is based on coded infrared light. A marker transmits a unique light code, which is captured by a network of high-speed cameras.
These cameras use our image processing algorithms to detect and decode the marker signals within less than 10 ms. The combined network of cameras accurately determines the full 6-DoF pose (position and orientation) of each marker with sub-millimeter-level accuracy, confirmed by our accuracy report.
Thanks to the coded light technology, markers can be detected reliably even in direct sunlight, making this solution ideal for both indoor and outdoor environments. The unique code also allows each marker to be uniquely identified and precisely tracked throughout the 3D measurement volume.
Compared to conventional radio-based RTLS, like UWB or BLE, our optical solution offers:
- Superior accuracy (0.33 mm RMS length measurement error)
- Full 6-DoF (6 Degrees of Freedom) pose – not just a position
- Faster tracking (66.6 updates per second)

Starter Kit
For € 7,965 (net, excl. VAT) – available from Q2 2027 – you get everything you need to track sub-millimeter 6-DoF poses on day one:
- 2× sensors (2.3 MP, 200 fps, PoE)
- 1× active marker (battery-powered)
- 1× calibration marker
- 1× PoE switch and all needed cables

Integration
The sensors do all the tracking themselves and stream finished 6-DoF poses over the network. Your PC just receives the data, so its full computing power stays free for your application.
- Open source API (MIT) for C, C++, Python, Rust and .NET
- ROS2 node for robotics applications
- Automatic device discovery on the local network
- Accuracy estimate with every pose (position and rotation error, sensors used)
