PROBLEM TO BE SOLVED: To provide a projectile calculation system and a method therefor for a golf ball which facilitates the determination of the projectile of the golf ball until the hit ball lands on the ground. SOLUTION: The projectile calculation system which calculates the projectile of the golf ball until the ball is hit and land on the ground has an initial projectile measuring means which measures the initial speed of the golf ball immediately after the hitting thereof, the angle at the start of hitting and the degree of back spin, a yardage measuring means which measures the yardage of the golf ball from the hitting point to the landing point thereof, a flight time length measuring means which measures the flight time length until the golf ball land on the ground after the hitting thereof and a calculation means which calculates the projectile of the golf ball based on the initial speed immediately after the hitting thereof, the angle at hitting, the degree of back spin, the carry and the flight time length thus measured.
