The Here3 GPS is a high precision GNSS system, which also supports RTK navigation mode, that uses the CAN protocol for highly reliable communications with the flight controller.

It is also designed to be dust-proof and splash proof. Equipped with STM32F302 processor, the Here3 provides faster processing speed and better reliability than previous generations. The Here3 has built-in sensors including a compass, gyroscope, accelerometer, and status LED. It runs on a Chibios real-time operation system and it's open source structure is ideally suited to developers who need specialized requirements for their navigation system.

Features:

• Cost efficient, high precision and RTK supported GNSS chip (base station needed for RTK).Positioning accuracy down to centimetre-level in an ideal environment.
• Brand new design with improved visibility on signal LEDs. 
• Better dust proof and water repellent design.
• High data rate, upgradeability, noise immunity, and real-time features benefited from CAN protocol.
• Equipped with STM32F302 high-performance processor in real-time operation system. 
• Framework developed by Hex provides additional stabilities. 
• Supports future firmware updates.
• Supporting ground control station available. Easy update from Mission Planner.
• Built-in a complete set of Inertial Measurement Unit processors (compass, gyroscope, and accelerometer), which satisfies advanced navigation needs.
