Portable None Installation,High Accuracy Positioning–GAT20
GAT20 is a 4G positioning terminaldesgned specificaily for asset cargo transportation management. It has built-in light sensing, temperatureand humidity, and adopts a card-typedesign. The body is compact and easy to place in more application scenarios

Strong Precision Positioning Capabilities
Supporting GPS/AGPS/Beidou positioning, as well as Wi-Fi/cellular/Bluetooth positioning, this combination of multiple positioning methods ensures accurate positioning in diverse environments with minimal error. For example, in urban areas with dense buildings, Wi-Fi and cellular positioning can complement satellite signals. In open areas outdoors, GPS and Beidou positioning are primarily used for precise positioning
Excellent Battery Performance
The built-in 2500mAh/3.7V industrial-grade lithium polymer battery features a low-power design and exceptionally long battery life. This allows the device to operate without charging for extended periods, making it particularly suitable for scenarios requiring continuous positioning, such as vehicle tracking and asset tracking. This reduces the need for frequent charging and improves the device’s ease of use and reliability


Comprehensive Sensor Configuration
For example, in logistics, temperature and humidity sensors can monitor temperature and humidity changes in the transport environment to ensure the quality and safety of goods. Accelerometers and gyroscopes can monitor vehicle acceleration, deceleration, and cornering, enabling analysis of driving behavior and preventing damage to goods from severe vibration during transport
Tamper & Condition Alerts
The built-in light sensor triggers an alert when the package is opened. An optional gyroscope can detect shocks and rolls, providing warnings for rough handling to safeguard your assets
