LGT-92 includes a low power GPS module L70 and a 9-axis IMU for motion and altitude detection. The power for both the GPS module and the IMU can be controlled by MCU to achieve the best energy profile for different applications.
The LoRa wireless technology used in LGT-92 allows the user to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Also, it targets professional tracking services.
This GPS tracker can be set up as follows in a LoRaWAN network:
Compared to traditional GPS trackers (base on GPRS or Cellular network), LGT-92 uses much lower power consumption hence can last for a longer time. It doesn’t need cellular service; system integrator can build their tracking network base on LoRaWAN technology or Join the device to existing LoRaWAN networks.
This is powered by a 1000mA rechargeable Li-on battery and charging circuit, which targets for real-time tracking with short tracking uplink.
Also, LGT-92 is an open-source project, and it is based on the STM32Cube HAL drivers. Therefore, many libraries can be found in the ST site for rapid development.
This LoraWAN GPS tracker can be configured by sending AT Commands via a Serial Port Tool running on your computer. You can access the guide for AT Commands list here.
