HR-RTLS4 UWB TDoA Positioning System

TDoA positioning with networked anchors

HR-RTLS4 is a UWB time-difference-of-arrival development system. Anchors receive tag transmissions and report timing information to a positioning engine, which uses the anchor configuration to calculate positions. Plan synchronization, anchor geometry, the network and host processing as parts of the same RTLS.

Host and anchor integration

The HR-RTLS4 user manual describes UTM1 anchor Wi-Fi configuration and UDP reporting, plus the host connection and coordinate setup. Confirm the documented synchronization arrangement and supported tag settings for the supplied version. A working network connection alone does not prove that the timing and geometry are correct.

Start with a representative area and the required number of tags. Verify individual anchor reports, then assess static points, movement, coverage boundaries and interrupted communication. Define per-tag update requirements and positioning error separately; do not transfer tag-capacity or accuracy figures from a different RTLS implementation.

Documentation for development

The documentation set includes user, embedded-development and PC-engine manuals. It describes a C++/Qt host environment and development resources for adapting the positioning system. Confirm the exact software package, supported platform and licence terms for your delivery. The currently linked RTLS4 manuals are Chinese PDFs, with English integration guidance provided on this page.

See the manuals below, the UTM1 anchor, TWR/TDoA/PDoA comparison and UWB deployment guide. For two-way-ranging development, compare HR-RTLS1.
