RTK GNSS Personnel Tracker with 4G or LoRaWAN for Outdoor Worker Safety
The JSC-802R is a high-precision wearable personnel tracker developed for construction sites, open-pit mines, ports, energy facilities, industrial parks and other safety-critical workplaces. It combines RTK GNSS outdoor positioning with optional UWB, Bluetooth and Wi-Fi technologies for indoor and semi-indoor location monitoring. In open outdoor environments, the device can receive RTK correction data to deliver centimeter-level positioning under suitable satellite and network conditions. When a worker enters a building, tunnel, workshop or GNSS-denied area, the system can switch to UWB or Bluetooth-assisted positioning instead of relying on unstable indoor GPS signals. The JSC-802R also supports SOS alarms, man-down detection, configurable geofences, route history and worker-status monitoring. Location and alarm data can be transmitted through 4G, LoRa or a customized communication architecture and displayed on a web platform, Android application or iOS application.
