Abstract: A player position determining and course management system for a golf course having a plurality of roving units for use by players in playing the course is disclosed. Each roving unit includes a central processing unit (CPU) including a data processor for executing various tasks ranging from fastest-execution of a task to slowest execution of a task on a schedule of priorities of task completion, a real-time means for controlling the processor to give the tasks priority ranging from fastest execution of a task with highest priority to slowest execution of a task with lowest priority, and a means for precisely timing functions of the system including modulating means utilizing a common digital modulation technique for digitally modulating data transmitted to and from all of the roving units.

Abstract: A ball position determining and course management system for a golf course includes a base station for course management and a plurality of golf carts for use during play of the course. The base station and the golf carts are adapted to operate in conjunction with a system for use in determining the relative position of and distance between objects on the course. Each golf cart has a roof and a monitor for displaying a map of each hole of the golf course with its tee boxes, fairways, greens and cups, and hazards. The monitor is mounted on the underside of the roof for shading and ease of viewing in sunlight, and has a screen which is canted back by a predetermined angle to reduce the amount of light reflected from the screen into the eyes of a viewer seated in the golf cart. The underside of the roof has a diffuse, black coating to reduce the reflectivity of its surface and to enhance the contrast of the display on the monitor.
