Position Tracking Devices

[BRAVESaj25bd8]

I am currently in an engineering class in my senior year in high school and we are developing a device that needs to be able to track where a basketball player is on the court at any time. I have found multiple positioning devices online but can't see if there are any devices that are exactly what my group and I would need to track a basketball player on a court. If anyone has any information for me regarding accurate position tracking systems or devices, my group an I would appreciate the help immensely. We have had the ideas to have the basketball player wearing a device on his/her wrist and be tracked or possibly use a tracking system where they would need to wear nothing in specific when playing. This is only for playing basketball alone so there would be no need to distinguish between players. Once again, any help would be greatly appreciated.
