As a drone pilot with years of experience under my belt, the hum of rotors and the feel of precise control are second nature. But what truly allows us to push the boundaries of drone technology, to conduct increasingly complex missions safely and efficiently, is the continuous advancement of Sense-and-Avoid (SAA) systems. Imagine navigating a congested airspace, the sun glinting off a distant building, the wind subtly shifting – now picture your drone autonomously perceiving and reacting to its environment, a digital co-pilot ensuring a safe and smooth flight. That’s the promise, and increasingly the reality, of Sense-and-Avoid.
The following video highlights offer a fascinating glimpse into the evolution and practical implementation of this critical technology. From early radar systems retrofitted onto consumer drones to sophisticated AI-powered avoidance maneuvers, these moments showcase the ingenuity driving the future of safe drone operations. Let’s delve into these key developments that are reshaping our understanding of flight safety.
Key Takeaways: Charting the Course of Sense-and-Avoid
Early Adoption & Innovation (PMI RF Radar – Video 1): The PMI RF Radar system for the 3DR Solo highlights the initial push to integrate SAA into accessible platforms. This video demonstrates the practical steps of installation and underscores the core principle: detecting obstacles – even small ones like wires – to prevent collisions. Seeing the Doppler radar sensors being mounted offers a tangible picture of how early adopters tackled this challenge. This was about enhancing existing platforms with crucial safety features.
Consumer-Grade Advancements (Yuneec Typhoon H – Video 2 & Drones are Improving – Video 4 & Intel Demos – Video 5): Yuneec’s integration of Intel’s RealSense technology in the Typhoon H marked a significant leap for consumer drones. These videos from CES highlight the power of visual sensing – mapping and detecting objects in real-time. Visualize the drone effortlessly navigating a cluttered environment; that’s the power of this technology. The emphasis shifted from purely reactive avoidance to more proactive environmental awareness. The buzz around CES underscored the growing mainstream interest in these capabilities.
Autonomous Collision Avoidance in Action (Honeywell Aerospace – Video 3): Honeywell’s demonstration showcases the pinnacle of current SAA capabilities – truly autonomous detect-and-avoid. Imagine the tension in the air as two drones converge, then the smooth, decisive maneuver executed by the onboard system. This isn’t just about sensing; it’s about sophisticated algorithms making real-time decisions to prevent mid-air collisions with other aircraft. The focus here is on robust performance in complex, dynamic environments.
Understanding the Fundamentals (Sense and Avoid Explained – Video 6): This video provides a foundational understanding of SAA, exploring various technologies and their pros and cons. It’s a crucial reminder that there are multiple approaches to achieving effective SAA, each with its own strengths and limitations. Think of this as a pilot’s pre-flight briefing on the core principles at play. The discussion on passive radar and the challenges faced underscores the ongoing innovation and problem-solving within this field.
Piloting the Future: Trends in Sense-and-Avoid Technology
Analyzing these videos reveals a clear trajectory. We’ve moved from bolt-on solutions to integrated systems, from basic obstacle detection to sophisticated autonomous avoidance. The early focus was on retrofitting existing platforms, as seen with the PMI radar. This involved skilled technicians carefully integrating new hardware, a testament to the pioneering spirit of early drone enthusiasts. Then came the era of computer vision, exemplified by Intel’s RealSense. This shifted the paradigm, allowing drones to "see" and interpret their surroundings in a more nuanced way, paving the way for more intelligent navigation.
Today, companies like Honeywell are pushing the boundaries of autonomous flight with advanced radar systems and sophisticated algorithms capable of handling complex air-to-air scenarios. I’ve personally experienced the critical difference a reliable SAA system makes in high-pressure commercial operations, especially when unexpected air traffic appears. The trend is undeniably towards greater autonomy, where drones can react to unforeseen circumstances with minimal human intervention, making our skies safer and opening up new possibilities for drone applications. The computational power required for these advanced systems is immense, highlighting the critical role of advancements in processing technology. The integration of AI and machine learning will further enhance the predictive capabilities of SAA systems, allowing drones to anticipate potential conflicts and react even more proactively.
Your Flight Path to Knowledge: Exploring the Evolution of Drone Safety
The advancements in Sense-and-Avoid technology showcased in these videos are not just incremental improvements; they represent a fundamental shift in how we approach drone safety. From the early ingenuity of integrating radar onto existing platforms to the sophisticated autonomous maneuvers demonstrated by Honeywell, each step forward enhances the reliability and safety of drone operations. Scroll down to watch the video highlights and witness firsthand the innovations that are making our skies safer and unlocking the full potential of drone technology. Understanding these developments is crucial for any pilot, enthusiast, or anyone interested in the future of aviation.

PMI RF Radar Sense and Avoid MODEL: RSAAS 001 – Installation VideoPlanar Monolithics Industries, Inc.8,025 views | 78 | April 28 2017 18:55:20 (13 comments)[ Read more … ]
PMI MODEL: RSAAS-001 is a Radar Sense and Avoid System that has been designed to provide obstacle detection for the 3DR Solo drone. This system uses (four) Doppler Radar sensors to detect obstacles from all sides of drone. Using Doppler Radar allows obstacles from small size (such as wire or tree branch) to large (such as a wall) to be detected when in range. Mechanical mounting can be adapted to fit other UAV platforms. Low power requirements make this system ideal for UAV application. Each sensor has onboard adjustment for distance of detection. Communication with 3DR Solo over USB interface via 30-pin Accessories Port connector. Visit www.pmi-rf.com

Autonomous Detect-and-Avoid Demonstration | Drones | Honeywell AerospaceHoneywell Aerospace Technologies2,831 views | 47 | February 3 2022 15:38:06 (6 comments)[ Read more … ]
Watch as a drone piloted by Honeywell’s IntuVue RDR-84K swerves around an intruder aircraft in a high-stakes game of aerial dodgeball. This ability to avoid unexpected traffic is an important step toward self-flying aircraft. Join us in our test facility North of Phoenix to test Honeywell’s IntuVue RDR-84K. The purpose of running these different tests is to emulate some of the threats that’ll happen between a drone and a manned vehicle.
In this video, we are trying out our detect-and-avoid algorithm on two UAVs. Both the target and the sensing drone are going to be flying right at each other. The convergence speed and the distance is dramatically closing and using our radar technology, we’ll do an avoidance maneuver. The air-to-air is a challenging environment because the radar needs to have a lot of information on its own position to be able to take over the drone and to steer it in the right direction. It’s a complex algorithm that we’re implementing today.
See what happens with the IntuVue RDR84k and how the hard work of the engineers at Honeywell Aerospace paid off on this test day.

What is Sense And Avoid (SAA)?
Many people have asked me for some background on the SAA system for GA, drones and FPV models that I have been working on for the (almost) two years.
In this video I try to explain some of the basics of what an SAA system is, the various technologies that could be used to implement such a system and the pro’s/con’s of each.
As usual, some liberties have been taken in order to simplify things and I have not disclosed exactly how my own design has overcome the limitations that have prevented others from using technologies such as passive radar as an effective sense-element.
Readers should note that as of this moment in time, CAA New Zealand are actively standing in the way of my continued development of this system for what I believe are purely political reasons – a desire to protect MFNZ from some perceived challenge to their unhealthy monopoly over controlling the right to perform RC flight within 4Km of an airfield.
Disgraceful.
