Frequently Asked Questions:

Q1. How does the JIYI Terrain Radar Sensor enable "terrain following" for a drone?

Ans. The JIYI Terrain Radar Sensor continuously measures the drone's precise distance to the ground using 24GHz radar technology. This real-time altitude data is fed to the flight controller. The flight controller then intelligently adjusts the drone's height to maintain a constant, pre-set distance above the undulating terrain. This "terrain following" capability is vital for applications like agricultural spraying, ensuring uniform coverage regardless of ground variations.

Q2. What are the benefits of using radar over other sensors (like LiDAR or ultrasonic) for terrain following?

Ans. Radar offers significant advantages for terrain following, especially in real-world agricultural and industrial settings. Unlike LiDAR, which can be affected by dust, water droplets, or direct sunlight, or ultrasonic sensors, which have limited range and are sensitive to wind, radar performs reliably in challenging conditions like fog, rain, dust, and at night. Its robust penetration ensures consistent and accurate ground clearance measurements in varied environments.

Q3. Is the JIYI Terrain Radar Sensor difficult to integrate with a non-JIYI flight controller?

Ans. The JIYI Terrain Radar Sensor communicates primarily via a CAN (Controller Area Network) interface and is specifically optimized for seamless integration with JIYI's own K++ and KX series flight controllers, which have native support for its protocol. While CAN bus is a standard, using it with non-JIYI flight controllers would likely require custom firmware development or a dedicated CAN-to-UART/PWM converter and drivers to interpret JIYI's specific data packets, making it more complex than plug-and-play.
