GPS Tracker

A GPS tracker is a satellite-based location monitoring device installed on trucks, trailers, or individual shipments that transmits real-time position data to fleet management and shipment visibility platforms. In cold chain logistics, GPS trackers are frequently integrated with temperature sensors to provide simultaneous location and thermal condition monitoring, giving shippers and carriers continuous visibility into both where their freight is and what temperature conditions it is experiencing.

Modern GPS tracking devices use a combination of GPS satellite positioning, cellular network communication, and cloud-based software platforms to deliver location updates at intervals ranging from every few seconds to every 30 minutes depending on the configuration and service plan. The devices are typically hardwired into the trailer's electrical system or powered by long-life batteries that can last weeks or months between charges.

Integration with Cold Chain Monitoring

For refrigerated shipments, GPS trackers that include temperature monitoring capabilities provide exceptional value by correlating location data with temperature data. If a temperature excursion occurs, the combined data shows exactly where the excursion happened, whether the truck was moving or stationary, and how long the deviation lasted. This information is critical for root cause analysis, freight claim documentation, and carrier performance evaluation.

GPS tracking has become a baseline expectation in the cold chain industry. Major shippers and receivers require carriers to have tracking capabilities as a condition of doing business. The data feeds into transportation management systems and customer-facing portals that provide automated alerts for late shipments, geofence violations, and temperature deviations. This level of visibility enables proactive exception management rather than reactive problem-solving after damage has already occurred.
