Abstract | The precision of measurements ranged from 4.09% to 96.73% depending on tag location. The average accuracy of stationary tags was 0.126 +/- 0.278 m, improving to 0.063 +/- 0.066 m following automatic system updates. Only 0.62 % of measurements exceeded the 30 cm threshold. The proximity of cows to stationary tags was correctly identified in 81.42 % of cases, with misclassification amounting to just 9 minutes over 24 hours of observation. Tags fixed on the stick showed a precision of 84.6%, with the outermost tags positioned at an average distance of 0.41 +/- 0.20 m and 0.42 +/- 0.23 m from the central tag. Despite variations in accuracy and precision, the tags met the manufacturer’s specifications. The findings confirm the potential of UWB technology for livestock monitoring, welfare assessment, and behavioural research, including the study of social interactions and spatial behaviour. For commercial application, regular system updates and data calibration are recommended. |
