FAQ
FAQ
Can Haoru UWB positioning modules measure angles?
The Haoru ULM3-PDOA anchor measures angles over a ±60° range with ±5° accuracy. Standard tags such as ULM1 and ULM3 measure distance only and do not measure angles.
Do Haoru UWB modules need antenna calibration before use?
The source describes the modules as ready to use without user calibration. Check the applicable manual for factory calibration and any application-specific antenna-delay calibration requirements.
Is the Haoru UWB positioning system open source?
The source describes the Haoru UWB positioning system as fully open source, including embedded code, PC application code and algorithms. Development manuals and video tutorials are supplied to help customers learn and develop quickly. Confirm the licensing and available files for the specific product and firmware revision.
How can I display trajectories from UWB data? Is open-source software available?
The source describes embedded code, PC application code and algorithms as open source, with development manuals and video tutorials. Confirm the supplied software and licensing for the selected product.
Which Haoru products can quickly form a positioning system?
Haoru supplies modules and complete positioning solutions. Choose modules for product integration, or a complete system with anchors, tags and PC software for faster deployment. Select the configuration according to site size and indoor or outdoor use.
Why buy four anchors if three anchors can calculate a position?
1) Tags should operate inside the anchor coverage area. Four anchors can cover a rectangular area rather than a triangular one; the source describes an approximately doubled coverage area. 2) Wireless ranging can fail. With four anchors, a position can still be calculated when ranging to at least three succeeds; a three-anchor setup needs all three measurements to succeed. 3) A four-anchor, one-tag setup can be reconfigured as three anchors and two tags to learn multi-tag operation. 4) Four anchors can support 3D positioning when the installation spans length, width and height in a 1:1:1 arrangement.
