What You Need to Know About Tethered Drones

Drones have revolutionized the way we view the world, both literally and figuratively. With their ability to fly and capture images and data from above, they have found uses in a wide range of industries, including agriculture, construction, and military operations. But while drones have proven to be incredibly useful, they also come with some limitations, such as limited battery life and the need for a clear line of sight. This is where tethered drones come in.
Tethered quadcopters are exactly what they sound like: drones that are attached to a tether, or a cable, that provides power and a secure connection to the ground. This type of drone offers some key advantages over traditional, untethered drones.

Advantages of Tethered Drones

  • Continuous Power Supply: One of the biggest limitations of untethered drones is their limited battery life. With a tethered drone, however, power is supplied continuously through the tether, allowing for longer flight times and more stable operation.
  • Increased Stability: The tether also provides stability to the drone, reducing the risk of crashes or sudden movements. This is especially important in windy conditions, where untethered drones can be difficult to control.
  • Increased Data and Video Transfer Speed: By being connected directly to the ground, tethered drones can transfer data and video much faster than untethered drones, which rely on Wi-Fi or other wireless connections.
  • Increased Flight Time: As mentioned, tethered drones can fly for much longer than untethered drones, making them ideal for long-duration missions.
  • Security: With a direct connection to the ground, there is a reduced risk of hacking or other security breaches. This is especially important in military and security applications.

Types of Tethered Drones

  • Military Grade: These are high-end, heavy-duty drones designed for military use. They are typically made from durable materials and are equipped with advanced sensors and cameras.
  • Commercial Grade: These are lighter and more affordable drones that are designed for use in the commercial sector, such as construction and agriculture.

Considerations for Choosing a Tethered Drone

  • Purpose of Use: It’s important to consider what you want to use your tethered drone for, as different drones are better suited for different applications.
  • Required Flight Time: As mentioned, tethered drones can fly for much longer than untethered drones. However, the length of the tether can still limit the drone’s flight time, so it’s important to consider how long you need to fly.
  • Payload Requirements: Different drones can carry different payloads, such as cameras or sensors. Make sure to choose a drone that can carry the payload you need.
  • Budget: Tethered drones can range in price from a few hundred dollars for a DIY kit to several thousand dollars for a commercial-grade drone. Make sure to choose a drone that fits your budget.
  • Available Space for Tethering: Finally, consider the space you have available for tethering the drone. You will need enough room to safely fly the drone and to store the tether when not in use.

Maintenance and Upkeep of Tethered Drones

  • Regular Checks and Maintenance: Like any other drone, tethered drones need regular checks and maintenance to ensure they are operating safely and effectively.
  • Tether Management: The tether is an essential part of a tethered drone, so it’s important to manage it carefully.

Miscellaneous Maintenance Tips

Taking care of tethered drones involves regular checks and maintenance to ensure they are operating safely and effectively. This includes

  • Regular inspections: Check the drone and tether for any signs of damage or wear and tear.
  • Cleaning: Clean the drone and tether to remove dirt and debris that can interfere with performance.
  • Storing the tether: Store the tether in a safe place when not in use to prevent damage.
  • Managing the tether: When using the drone, make sure the tether is not tangled or knotted and is not interfering with the drone’s movements.
  • Protecting from the environment: Protect the drone and tether from weather, wind, and other environmental factors that could cause damage.

By following these guidelines, you can help ensure your tethered quadcopter continues to perform at its best and remains a valuable tool for your operations.

  1. How can I get a tethered drone?

There are two options for acquiring a tethered drone system: fully integrated or DIY.

A fully integrated system comes complete with all necessary components, including the ground station, winch, tethers, data transmission, communication links, and a drone equipped with sensors. This option offers the convenience of having everything work together seamlessly.

DIY integration involves connecting a winch, tether, power source, data transmission, and communication system to a drone and ground control station that you already own. This option is more affordable but requires effort to ensure compatibility between components. It is suggested to go for the former since it comes with the specifications for your job without any hassle to figure out technicalities on your own, thus avoiding any failures or damages to the drone.
