Improving Agriculture through Autonomy: Unlocking the Future of Farming with Autonomous UAS
As the global population continues to grow, resources are steadily decreasing. Accordingly, the increasing demand for food has led to a rise in the need for resources like water, fertilizers, and manpower. In response to this problem, the agricultural industry has turned to innovative solutions such as autonomous farming, but what exactly is it?
Consequences of growing population
Precision farming (also known as autonomous farming or precision agriculture) uses technology to maximize yields while minimizing the use of these resources, thus saving time and costs. One of these technologies, known as Unmanned Aerial Systems (UAS), has become essential in this process. By frequently collecting high-quality, real-time data, UAS enhance the monitoring of agricultural assets such as crops and livestock.
Based on findings from the European Union’s AFarCloud research project (Aggregated Farming in the Cloud), autonomous agriculture is advancing rapidly. The project demonstrates the potential of fully autonomous UAS operations, detailing its integration with other cyber-physical systems and regulatory challenges across Europe. Additionally, EU-wide policies are being introduced to enhance UAS operations, ensuring safety and promoting the use of autonomous systems in agriculture.

The Need for Autonomous UAS in Agriculture
How can farmers keep up with agricultural monitoring when traditional methods rely on human-operated drones, making them costly and less efficient? The reliance on human intervention limits the scalability of UAS applications, particularly in larger and more complex farm setups where continuous monitoring and data collection are essential.
To overcome these barriers, the goal is to advance UAS technology toward greater autonomy, thus reducing operational costs and improving versatility. The key challenge lies in developing agricultural drones that offer flexibility, robustness, and require minimal human involvement. A future vision of autonomous UAS is to integrate drones into a comprehensive Farm Management System (FMS), which collects and analyzes data from various sources, including drones and ground-based sensors. Such a system would enable automated decision-making, providing farmers with actionable insights for irrigation, fertilization, pest control and thus ensuring plant health without requiring specialized technical knowledge.

The Role of European UAS Regulations in Agriculture
To ensure safety and efficiency in drone operations, the development of UAS technology has triggered a need for regulations. The newly introduced European Union UAS regulations impact the deployment of autonomous drones in agriculture.
The primary regulatory framework consists of two key regulations:
The primary regulatory framework consists of two key regulations:
- EU 2019/945 - This regulation outlines the requirements for UAS, including rules for drone design, manufacturing, and operation.
- EU 2019/947 - This regulation classifies UAS operations into three categories based on risk: Open (low risk), Specific (medium risk), and Certified (high risk).
The regulations also introduce the European Commission framework “U-Space (unmanned aircraft traffic management)”, which aims at ensuring safe integration of UAS into manned airspace. U-Space services will roll out in phases, with full implementation expected by 2030. Due to the low-risk nature of agricultural drone operations, they are likely to be among the first approved for fully autonomous usage under U-Space.
Beyond Remote Control: The Rise of Fully Autonomous UAS
Increasing the Level of Autonomy (LOA) in UAS operations is a significant part of the AFarCloud project. By integrating drones for agricultural use with middleware systems and developing advanced onboard functionalities, these drones are able to operate independently, using AI and sensors to make real-time decisions and complete missions without human intervention. To enable real-time communication between drones and the cloud-based platform, the Data Distribution Service (DDS) protocol was used.
To achieve full autonomy, battery life and communication infrastructure had to be further improved. Autonomous charging stations allowed UAS to dock and recharge without human intervention, thus enabling longer missions. A drone capable of operating for extended periods without requiring battery changes or direct human oversight is a big step into revolutionizing precision agriculture.

How are drones used for agricultural purposes?
Large-Area Monitoring
With the ability to cover vast areas, fixed-wing drones can monitor multiple farms in one flight. This reduces operational costs for farmers by providing shared data services. Drones equipped with RGB and infrared (IR) cameras can identify foreign objects like deer fawns or metal debris that could harm harvesting machinery or livestock.
Remote Sensor Data Collection
UAV remote sensing agriculture enables drones to collect data on environmental factors such as humidity and temperature through ground-based sensors. This integration helps to overcome the limitations of wireless sensors with restricted battery life by using drones to retrieve sensor readings.
In-Situ Measurements and Manipulation
Novel applications of UAS include drones equipped with manipulators to collect physical samples or perform simple tasks in hard-to-reach areas. This capability could revolutionize how farmers assess crop conditions or sample soil without damaging the terrain.
Low-Altitude Grass Analysis
A prototype UAS equipped with near-infrared (NIR) sensors was developed to analyze grass maturity for dairy farming. By measuring the digestibility of grass in real-time, farmers can optimize silage harvesting, which is crucial for ensuring feed quality.
Multispectral Imaging for Precision Farming
Drones equipped with multispectral cameras can collect data on crop health by capturing various spectral bands such as RGB, near-infrared, and red-edge. These images are then processed to generate detailed maps, which allow farmers to monitor nutrient deficiencies, pest infestations, and water stress.
Autonomous Drone Charging and Mobility
Autonomous charging is key to enabling long-term UAS missions. The development of drone charging stations enables recharging without human intervention. Additionally, integrating these charging stations with autonomous ground vehicles (AGVs) enhances the mobility of UAS operations across large farms.
System Requirements for Agricultural Unmanned Autonomous Vehicles (UAV)
To implement autonomous UAS in agriculture, several critical system requirements must be considered:
- Autonomous Base Stations - These stations support UAS with battery recharging and data transfer, allowing continuous operations without human intervention.
- Modularity - UAS must be designed in a modular fashion so that parts and payloads can be easily replaced depending on the task. This flexibility is crucial for the harsh environments typically found in agriculture.
- High-Precision Navigation - Precision farming demands accurate positioning, which can be achieved by using technologies like real-time kinematic (RTK) and post-processed kinematic (PPK) GNSS.
- Adaptable Communication Systems - UAS operations on farms, often in rural areas, require robust communication systems. The project tested various communication technologies, including Wi-Fi, Bluetooth, and 4G, for their suitability in different agricultural scenarios.
Challenges and Opportunities
While the technological advancements in autonomous UAS are promising, several challenges remain. For instance, there is a need for a standardized framework that supports the seamless integration of UAS with other farm systems. Additionally, regulatory hurdles, particularly around fully autonomous operations, must be addressed to unlock the full potential of UAS technology.
Despite these challenges, the future of UAS in agriculture looks promising. Autonomous UAS systems can significantly reduce labor costs, improve decision-making, and enhance productivity on farms. The flexibility of UAS also enables multiple use cases beyond simple crop monitoring, including livestock management, soil analysis, and even fruit picking. Furthermore, the AFarCloud project has demonstrated the feasibility of using drones in conjunction with AI-driven data analysis, offering farmers a more comprehensive solution for managing their operations.
