after a flat fall and collapse of the gear and undercarriage I put my frankenstein 520 on the shelf. I was able to locate a rebuild kit so I'm now bringing it back, i think. I am haveing issues with firmware update and intial radio connection.
here are some answers
The Yuneec Typhoon H520 drone comes equipped with a ST16S Ground Station remote controller. This controller is a major part of the system, providing the interface for flight control and live video streaming from the drone's camera.
Here are some key details about the radio and communication system on the Yuneec Typhoon H520:
-
ST16S Ground Station Controller:
- The ST16S is a tablet-based controller that integrates a 7-inch touchscreen display, allowing for both control and live FPV (First-Person View) video feed.
- The radio communication between the drone and the ST16S controller typically operates on 2.4 GHz for control and 5.8 GHz for video transmission.
-
Communication Protocols:
- The 2.4 GHz band is used for control, ensuring reliable command input and telemetry data between the drone and the ground station.
- The 5.8 GHz frequency is used for transmitting high-definition video, ensuring minimal latency and better video quality during flight.
-
Radio Range:
- The radio communication typically has a range of around 1 km (0.6 miles), though this can vary depending on environmental factors like interference or obstacles.
This system provides solid and reliable control and telemetry, suitable for professional use cases like mapping, inspection, and public safety operations.
If you're asking about the internal radios used in the drone itself for communication, the Typhoon H520 uses built-in 2.4 GHz and 5.8 GHz radios for communication and video transmission to the ST16S ground station.
You're correct—aside from the ST16S ground station controller, the Yuneec Typhoon H520 has multiple radios involved in its communication system, including ones in both the camera and the airframe. Here’s a breakdown of the radios you are referring to:
1. Airframe Radio
The airframe of the Typhoon H520 houses the main flight controller and the radio responsible for handling communication between the drone's flight controller and the ST16S ground station.
- Radio Frequency: This is typically a 2.4 GHz radio for control communication (i.e., sending commands from the ground station to the drone).
- Function: This radio manages the link for the drone’s control signals (stick inputs, GPS positioning, telemetry) and can also handle features like obstacle avoidance, status feedback, and flight telemetry (speed, battery life, altitude, etc.).
- Range: The range of the airframe radio varies depending on environmental factors, but typically around 1 km (0.6 miles).
2. Camera Radio
The camera on the Yuneec Typhoon H520, specifically the E90 camera or similar models, has its own radio system, typically used for video transmission. This radio allows live streaming of the HD video feed to the ST16S ground station.
- Radio Frequency: The camera typically communicates over the 5.8 GHz frequency for video transmission to the ST16S.
- Function: This radio handles the transmission of live video from the camera mounted on the drone to the screen on the ST16S. The camera itself may have additional communication systems that help with controlling the camera's gimbal, camera settings, and video data encoding for transmission.
- Video Transmission: The 5.8 GHz band provides a reliable, low-latency connection that is crucial for live video streaming during flight, especially in inspection and survey tasks where real-time video is important.
How It Works Together:
- Flight Control Radio (Airframe): Operates on the 2.4 GHz frequency, ensuring reliable control of the drone, including telemetry and GPS data. This is the primary communication channel between the drone and the ST16S.
- Camera Video Radio: Operates on 5.8 GHz, transmitting HD video from the camera to the ST16S controller for live viewing.
The two radios work simultaneously to ensure that you have both control and live video feed without interference, and they typically use different frequency bands to minimize conflicts.
Summary of Radios:
- Airframe (Flight Controller): 2.4 GHz radio for control and telemetry data.
- Camera (Video Transmission): 5.8 GHz radio for live video feed.
This separation of radio frequencies allows for a stable and efficient communication system, ensuring that the Typhoon H520 can transmit high-quality video while maintaining reliable control.
If you're experiencing trouble with the **2.4 GHz radio connection** (the control link between the drone's airframe and the ST16S) but the **GPS** is still functioning fine, it suggests there may be an issue with the **control signal** specifically, rather than general flight or navigation systems. Since the GPS works, the drone is still receiving positioning data, which implies it's still receiving basic power and perhaps telemetry signals, but not full control input.
Here are a few troubleshooting steps to help resolve the issue:
### 1. **Check the Controller and Drone's Antennas**
The **2.4 GHz radio** system relies on antennas for stable communication between the drone and the controller:
- **ST16S Controller Antennas**: Make sure both antennas on the **ST16S** are properly attached and not damaged. Sometimes, a loose or broken antenna can significantly impact the connection.
- **Airframe Antennas**: The drone’s antennas also need to be intact and properly connected. Ensure that they are positioned correctly and are not obstructed by any part of the airframe.
### 2. **Interference or Obstructions**
2.4 GHz is a commonly used frequency, so it's susceptible to interference from other devices that use the same frequency range:
- **Nearby Wireless Devices**: Other Wi-Fi networks, Bluetooth devices, or even other drones nearby can cause interference. Try flying in a less congested area or turning off nearby devices that may be emitting 2.4 GHz signals.
- **Physical Obstructions**: Large objects (like buildings, trees, or even people) can block or weaken the 2.4 GHz signal, especially if you're flying at a distance or behind obstacles. Try flying in an open area with minimal interference.
### 3. **Radio Frequency Channel Settings**
The Typhoon H520 uses **auto-channel selection** on the 2.4 GHz frequency, but sometimes the controller and drone may be stuck on a noisy or crowded channel:
- **ST16S Settings**: Check the **ST16S** controller settings to see if you can manually change or reset the radio channel. Some users have had success with switching to a different channel in crowded environments.
- If possible, try to **reset the communication** between the drone and controller to ensure they're properly paired again.
### 4. **Check for Firmware Updates**
Occasionally, firmware issues can cause connectivity problems between the drone and controller, even if the GPS and other systems are working:
- **ST16S Firmware**: Make sure your **ST16S controller** is running the latest firmware. Check for updates in the **Settings** menu of the controller.
- **Drone Firmware**: Similarly, ensure the drone's firmware is up to date. You can check this through the **Yuneec app** or the drone's on-screen display.
### 5. **Re-pair the Controller and Drone**
If the drone and controller have lost their pairing or communication, resetting the link may help:
- **Power off** both the drone and the ST16S controller.
- **Power on the drone** first, then **turn on the ST16S controller**.
- If necessary, manually re-pair the controller and the drone by following the pairing process in the controller’s settings menu.
### 6. **Battery Power Levels**
Low battery levels on either the drone or the controller can cause issues with communication:
- Ensure both the drone's **battery** and the **ST16S** controller have adequate charge.
- Sometimes, low battery levels on the controller or drone can cause signal strength to drop, even if the GPS and other systems are still operational.
### 7. **Check for Internal Hardware Issues**
If none of the above steps help, it’s possible there’s an issue with the internal 2.4 GHz radio hardware, either in the drone’s airframe or in the ST16S controller:
- **Internal Radio Problems**: If you're still having trouble after checking all external factors (antennas, interference, etc.), you may want to contact Yuneec support to see if there’s an issue with the **radio module** in either the drone or the controller. A malfunctioning radio could be the cause of poor control communication.
### 8. **Perform a Range Test**
If possible, perform a **range test** in an open, safe area. Walk away from the drone with the controller while monitoring the telemetry:
- If the radio connection drops as you move further from the drone, it might indicate an issue with either the controller's antenna, the drone’s internal radio, or the environment causing signal interference.
### 9. **Check for Environmental Factors**
If you're flying in an area with a lot of **electromagnetic interference** (e.g., near power lines, radio towers, or large metal structures), the 2.4 GHz signal may be blocked or weakened.
---
### Summary Checklist:
- **Check antennas** on both the controller and drone.
- Ensure you're flying in an area with minimal **interference** from other wireless devices.
- Reset or change **radio channels** via the ST16S controller settings.
- **Update firmware** on both the controller and drone.
- Try **re-pairing** the drone and controller.
