I’m working on a project that requires precise real-time location tracking using Ultra-Wideband (UWB) technology. I chose UWB due to its pricing and accuracy compared to other sensors and due to project restrictions. The specific use case involves determining the exact distance between a moving horse and a stationary object. The UWB sensor needs to be attached to the horse’s leg. Hence, GPS or lidar sensors (which need a clear line of sight) would not be suitable. The receiver/anchor will be placed next to the stationary object. Here are the detailed requirements for the UWB tag:

• High Transmission Frequency: The sensor must support a minimum transmission frequency of 100 Hz to ensure real-time data updates.

• High Accuracy: The system should provide location accuracy of ±5 cm. It’s acceptable if this accuracy is achievable through calibration.

• Outdoor Use: The sensors need to be designed for outdoor environments, meaning they should be weather-resistant and durable.

• Small size & light: Needs to be attached to horse’s leg, so it should have a suitable size.

• Add on (not a hard requirement): Accelerometer included in the sensor

I’ve explored several options, but none have fully met my requirements. For example:

• Inpixon Sensor Ultra offers high accuracy and BLE capabilities but is mainly marketed for indoor use.

• Pozyx UWB Tags have good accuracy and are robust, but their update rates and outdoor suitability are unclear.

• KKM K4W UWB Tag is industrial-grade with good accuracy but doesn’t specify 100 Hz update rates.
  Zebra UWB System, KINEXON RTLS, and Eliko UWB RTLS come close, with configurable update rates and robust designs, but still fall short of the 100 Hz requirement or specific outdoor durability.

Given these considerations, can anyone recommend a UWB sensor system that fits all these criteria? Detailed insights into the practical performance of the recommended systems in similar use cases would be highly appreciated. Alternatively, if I am on the wrong track with UWB sensors, I would appreciate any other suggestions you might have!

Thank you for your help!
