Vicon reference system +/-1mm, Vicon accuracy better then 5mm at 20m distance. Vicon reference system:, a millimeter accurate tracking system using infrared reflection of small reflective balls Limited in range to about 20meter for outdoors mainly because of illumination issues Tracab +/- 30cm:optical tracking systems non-intrusive solution to track both players and ball (no physical intervention by technical equipment) no data loss due to sensor failure since data can always be restored from video footage. data loss occur by obfuscation between players and for the ball mostly around the goal area. alleviated by placement of 10+ camera's around the field driving up cost accuracy decreases with distance where 70m is a practical limit for sub 20cm accuracy. ZXY LPS accuracy +/- 60cm: EPTS (Electronic performance and tracking systems) 1
