Abstract: A system is provided for measuring field conditions of soccer fields. In one embodiment, an inventive system includes a central management system; a testing soccer ball for testing a ground of a soccer field; a GPS receiver mounted inside the testing soccer ball, wherein the GPS receiver detects velocity of the soccer ball; sends RF signals to the central management system; locates current position of the soccer ball; and locates current attitude of the soccer ball from the ground of the soccer field. The system also includes a RFID tag including a RFID antenna mounted on surface of the testing soccer ball; a soccer ball transmitter located on one end of a field; a RFID reader located on another end of the field, wherein the reader detects the RFID tag when the soccer ball passes through the reader. The system further includes a control processing unit and a memory located inside the testing soccer ball.
