Player Proximity Systems (PPXS) develops a suite of applications to enhance the control of sprinklers on golf courses. The system is designed to allow a course to water when they need rather than when they can fit in between play. PPXS members are tracked as they move around the course and as they approach an operating sprinkler it's cycle will be paused until they leave the area. Developed initially to turn sprinklers off as players approach, the system capabilities have been increase to provide more specific control of watering cycles.
