Abstract: The present invention provides a golf simulator comprising a launch area facing a screen at which the ball is driven and used to display part of a golf course. Sensors detect the impact of a ball on the screen, and/or flight towards it, and/or club head trajectory. The launch area is a playing surface panel tiltable by a displacement device, to provide a desired slope angle &agr; and slope direction &bgr; relative to a driving direction. A computer is connected to the sensors and displacement device, and programmed to control display of the course, based on its topography, and position of the launch area, and compute an estimated ball trajectory, ball lie based on the estimated trajectory and landing zone topography. The computer then controls the screen display and displacement device so that the next drive can be played from a realistic lie.

Abstract: The present invention relates to a tiltable tee apparatus suitable for use in practising golf driving. The apparatus comprises a ground support, and a tee platform rotatably mounted on the ground support. The tee platform comprises a base portion and a playing surface panel hingedly connected at a first edge portion to a corresponding edge portion of the base portion. The playing surface panel is supported at a jack support portion remote from the first edge portion on an upper end of at least one screw jack pivotally connected thereto. At least one screw jack has its lower end pivotally connected to the base portion. One of the ground support and the tee platform base portion has a fixed spur gear secured thereto in a substantially horizontal plane on the rotational axis of the rotatable tee platform, and the other has mounted thereon a drive motor with an elongate toothed drive output transmission member for driving engagement with the spur gear so as to rotate the tee platform in use of the apparatus.
