OEM Data Delivery has introduced the GSE Service Tracker, a radio-frequency technology that tracks, and transmits to headquarters, detailed information on dispensed fuel, equipment utilization, and equipment maintenance tasks, for use in reporting, purchasing and decision-making. GSE Service Tracker tracks location, the equipment in service, date/time, work classification (hydraulic, electrical, mechanical, etc.) and service tasks performed on passenger bridges and lifts, catering trucks, baggage handling systems and fuel trucks. It is wireless, and paperless. Use and service alerts are tracked continuously via an on-site tower. The tower interfaces with a PDA data collector, or computer. Data is typically downloaded into a web report. The system operates continuously, providing management the analytics for understanding what tasks are most time-consuming, what equipment requires the most service attention, and other useful metrics.
