Specifications and performance
Can Haoru UWB positioning modules measure angles?
UWB PositioningAnswer
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.
Specifications and performance
What determines UWB update rate and end-to-end latency?
UWB PositioningAnswer
Per-tag update rate is how often a new measurement or position is produced for one tag. End-to-end latency also includes transmission, host processing and filtering. The fastest mode is not the default for every product or tag count. For example, the ULM1 manual specifies a 10 ms single-tag cycle at 6.8 Mbps, while the ULM3 manual describes a 12 ms slot at 850 kbps. Use the schedule for the actual model and firmware, then measure application latency under the intended tag count and network load. Do not treat radio data rate in Mbps as a position update rate.
Specifications and performance
Does Haoru offer centimeter-level positioning products?
UWB PositioningAnswer
Yes. The source states that the product range supports positioning accuracy of up to 10 centimeters under the applicable operating conditions.
Specifications and performance
What is the ranging accuracy of the modules?
UWB PositioningAnswer
The source gives centimeter-level ranging accuracy of 10 centimeters, with performance affected by factors such as obstructions and metal interference. Check the specific model's ranging specification.
Specifications and performance
What positioning accuracy can the UWB3000 achieve?
UWB PositioningAnswer
For 2D positioning in the XY plane, the source gives approximately 10cm accuracy in ideal open, unobstructed line-of-sight conditions. For 3D positioning, Z-axis height accuracy is approximately 30cm. Metal, walls, dense shelving and other obstructions can degrade performance, with source examples of errors from 50cm to 1m.
Specifications and performance
How are positioning accuracy and operating range related?
UWB PositioningAnswer
The source specifies XY accuracy of 10cm (CEP95) and Z accuracy of 30cm (CEP95). Operating range does not directly determine positioning accuracy. The higher transmit power of LD600 can produce noticeable multipath effects in a small 5 × 5m area; the source recommends it for larger spaces.
Specifications and performance
What are the dimensions of the positioning system's main board?
UWB PositioningAnswer
The referenced board is 10cm long and 6cm wide. Verify the specific model and revision.
Specifications and performance
How long do the UWB tags operate on a battery charge?
UWB PositioningAnswer
The source gives five days for the wristband tag and fifteen days for the badge tag. Battery life depends on the applicable configuration and use.
Specifications and performance
What battery runtime does the LD600 provide?
UWB PositioningAnswer
The source gives eight hours for the referenced configuration.
Specifications and performance
Do UTM1 and LD150 include batteries?
UWB PositioningAnswer
Yes. The source states that both referenced configurations include batteries.
Specifications and performance
What is the update interval with two tags?
UWB PositioningAnswer
For the referenced one-anchor, two-tag setup, the default interval is 48ms. It can be adjusted to a minimum of 24ms.
Specifications and performance
Can the system calculate a height difference?
UWB PositioningAnswer
For the referenced configuration, distribute the anchors in a cubic spatial arrangement as shown in the installation guide to obtain a Z-axis coordinate.
Specifications and performance
Can ranging be performed between vehicles rather than only between a tag and anchor?
UWB PositioningAnswer
Yes, using distributed ranging. For vehicles 1, 2 and 3, vehicle 1 can obtain ranges 1–2 and 1–3; vehicle 2 obtains 2–1 and 2–3; vehicle 3 obtains 3–2 and 3–1.
Specifications and performance
What is the positioning data update interval?
UWB PositioningAnswer
For the referenced configuration, the default is approximately 2.8 seconds, adjustable to approximately 1.2 seconds. This is configuration-specific and differs from high-update-rate modes.
Specifications and performance
What area can one anchor cover?
UWB PositioningAnswer
For the TDoA UTM1 configuration, the stated maximum ranging distance is 150m and the positioning range is approximately 50m, under completely open, unobstructed conditions. Positioning requires the applicable multi-anchor layout.
Specifications and performance
How long do badge and wristband tags operate on a charge?
UWB PositioningAnswer
At eight hours of use per day, the stated runtime is approximately fifteen days for a badge tag and five days for a wristband. Both normally use motion detection and enter sleep when stationary.
Specifications and performance
What is the operating temperature range?
UWB PositioningAnswer
The referenced module is specified for −20°C to 70°C. Verify the specification for the selected model.
Specifications and performance
What update rate do the positioning modules support?
UWB PositioningAnswer
The fastest referenced single-tag rate is 100Hz, or 10ms per update. Overall system latency increases as the number of tags increases.
Specifications and performance
What ingress-protection ratings are available?
UWB PositioningAnswer
The original answer gives IP31 for standard modules, with IP65/IP67 enclosed options for outdoor or damp environments. Verify the enclosure and rating of the exact product.
Specifications and performance
What operating temperatures are supported?
UWB PositioningAnswer
The modules use an industrial wide-temperature design. Check the particular module's manual for the numerical temperature limits.
Specifications and performance
How are the modules powered?
UWB PositioningAnswer
Most referenced modules use 5V DC through USB or a terminal. Wearable wristband and badge tags contain lithium batteries and support USB charging.
Specifications and performance
What is the standard operating temperature range?
UWB PositioningAnswer
The referenced standard range is −20°C to +70°C. Verify the chosen model's specification.
Specifications and performance
How does configured tag capacity affect UWB update intervals?
UWB PositioningAnswer
In the documented TDMA configurations, each configured tag slot contributes to the total cycle, including slots whose tags are absent. At 110 kbps, the ULM1 manual describes 28 ms per tag slot: four slots produce a 112 ms cycle, or about 8.9 updates per second per tag. At 850 kbps, the ULM3 example uses 12 ms per slot: eight slots produce a 96 ms cycle, or about 10.4 updates per second per tag. These examples apply to their specified modes; other firmware and configurations require their own schedule. They describe update intervals, not total application latency.
Specifications and performance
What battery or power-bank runtime is available?
UWB PositioningAnswer
Runtime depends on battery capacity and positioning frequency. Referenced ULM1 power-bank configurations give approximately ten hours for an anchor and fifteen hours for a tag. LD150/LD600 internal-battery configurations give approximately eight hours for an anchor and twelve hours for a tag.
Specifications and performance
Are IP65/IP67 module options available?
UWB PositioningAnswer
Yes. Applicable enclosed products such as IGA02-EP and ULM1-SH are available for outdoor or damp conditions. Verify the exact enclosure rating.
Specifications and performance
Are ranges below 1m less accurate?
UWB PositioningAnswer
Short-distance ranging can be affected on DW3000-based modules such as ULM3 and ULM3-PDOA. The referenced answer states that performance is generally maintained above 0.5m, while distances below 0.5m can show larger errors due to antenna and signal-processing effects. Verify short-range behavior in the intended configuration.
Specifications and performance
Can positioning accuracy be improved further?
UWB PositioningAnswer
For the referenced hardware and algorithm, ideal-condition figures are approximately 10cm in 2D and 30cm on the Z axis. Further improvement may require additional engineering, such as UWB/IMU, LiDAR or vision fusion; denser or better anchor geometry; and improved filtering or calibration. These approaches must be evaluated rather than treated as guaranteed accuracy improvements.
