HERON DEVELOPMENT BOARD
The first domestic RTK-GPS development system Heron RTK-GPS System Multi-Band Real Time RTK-GPS system is a complete and integrated system for sensitive field studies such as lokaysan control, position and flight control. You can perform all precise positioning operations with centimeter-level accuracy with the Heron RTK-GPS system.
Heron RTK-GPS System is an RTK-GPS system consisting of a base station and rover boards that provide data exchange with 3 different communication methods. In addition to Lora or Zigbee methods, which are long-distance communication methods, as a communication method, it consists of data link boards that allow communication without distance using 4G-LTE technology. The Heron RTK-GPS system is a domestic precision positioning system that offers reasonable price and alternative communication methods with centimeter accuracy from existing systems in the market.
Quectel EC25-EU Mini PCIe Module is an LTE Cat 4 Wireless Communication System specifically designed for M2M and IoT domains. A PCI Express interface uses the Mini Card interface. This module meets the requirements of customers’ applications to raise cost and power consumption, and supports a maximum download speed of 150Mbps and a maximum connection speed of 50Mbps.
At the center of this module is the ESP32-Wroom chip. Embedded chips are designed to be scalable and adaptable. There are two CPU cores that can be controlled separately, and the CPU clock frequency can be adjusted between 80 MHz and 240 MHz. Users can also turn off the CPU and use a low-power coprocessor to constantly monitor peripherals for changes or threshold violations.
