A sport monitoring system includes a projectile(s) (e.g., ball), sensor units for players to wear, and a data processing arrangement. The projectiles are useable in a game played by players. Each projectile has a motion sensing arrangement for generating motion-indicative signals, and a data recording arrangement for recording the motion-indicative signals as a function of time. Each sensor unit is provided with a motion sensing arrangement for generating a motion-indicative signal(s), and a data recording arrangement for recording the motion-indicative signals as a function of time. The data processing arrangement receives data pertaining to the motion-indicative signals from the projectiles and/or the sensor units, and performs a temporal correlation of the data to determine one or more periods of time when the projectiles are likely to be spatially closely associated with the players (e.g. ball possession). |
