The present study aims to identify the accuracy of the NBN23&reg, system, an indoor tracking system based on radio-frequency and standard Bluetooth Low Energy channels. Twelve capture tags were attached to a custom cart with fixed distances of 0.5, 1.0, 1.5, and 1.8 m. The cart was pushed along a predetermined course following the lines of a standard dimensions Basketball court. The course was performed at low speed (&lt, 10.0 km/h), medium speed (&gt, 10.0 km/h and &lt, 20.0 km/h) and high speed (&gt, 20.0 km/h). Root mean square error (RMSE) and percentage of variance accounted for (%VAF) were used as accuracy measures. The obtained data showed acceptable accuracy results for both RMSE and %VAF, despite the expected degree of error in position measurement at higher speeds. The RMSE for all the distances and velocities presented an average absolute error of 0.30 &plusmn, 0.13 cm with 90.61 &plusmn, 8.34 of %VAF, in line with most available systems, and considered acceptable for indoor sports. The processing of data with filter correction seemed to reduce the noise and promote a lower relative error, increasing the %VAF for each measured distance. Research using positional-derived variables in Basketball is still very scarce, thus, this independent test of the NBN23&reg, tracking system provides accuracy details and opens up opportunities to develop new performance indicators that help to optimize training adaptations and performance.
