China Eforthink Dual-Frequency Differential GNSS Positioning Work Permit Card - Top Suppliers & Factory Solutions

The Eforthink Intrinsically Safe Dual-Frequency Differential GNSS Intelligent Positioning Work Permit Identification Card is an advanced RTLS (Real-Time Location System) terminal designed for effective personnel tracking in both indoor and outdoor environments. As a leading Personnel Location Tag developed by top China suppliers, it employs cutting-edge RTLS technology to ensure high-precision, real-time positioning even in complex settings, This innovative device incorporates UWB location technology, adhering to the 802.15.4 2011 UWB standard, alongside uBeacon, iBeacon, AOA (Angle of Arrival), and ZigBee communication protocols operating at 915MHz and 2.4GHz for reliable indoor positioning. In outdoor situations, its dual-frequency GNSS module surpasses traditional single-frequency systems by providing centimeter-level accuracy through dual-frequency RTK differential positioning, especially when used with ground-based differential reference stations. This hybrid technology allows for seamless operation across mixed environments, granting administrators real-time visibility into personnel movements, Safety is paramount, and this terminal includes essential features such as boundary alerts, proximity warnings for hazardous areas, and an SOS emergency button. Its 2.7-inch e-ink screen displays vital information, including messages, weather updates (dependent on network access), and alarm statuses. As part of a comprehensive RTLS system, this device also facilitates instant distress reporting, alerts for fire, flood, or hazardous material leaks, and enables automated health monitoring, ensuring swift emergency responses, Manufactured by a trusted factory, the Eforthink Intelligent Positioning card exemplifies reliability and innovation in personnel tracking solutions
