GreenSight Developing Novel Aircraft Detection System With NASA

July 20, 2023

GreenSight is working with NASA to develop novel sense and avoid technology.

GreenSight, Inc. is proud to announce a Phase II Small Business Innovation Research (SBIR) award from NASA to help prepare its Automated DEcision Support System for Sense and Avoid (ADeSSSA) for commercialization. AdeSSSA uses novel  machine learning to fuse visual, acoustic and RF data to reliably detect aircraft from a distance. This system significantly improves performance over systems that use single methods of detection.

ADeSSSA has multiple applications in unmanned aircraft traffic management as well as aerial detection for counter-unmanned systems.

ADeSSSA improves safety for mixed operation of unmanned and manned aircraft in complex environments like wildfires where low altitude manned aircraft operations are happening at a rapid pace. Currently operation of unmanned aircraft in these environments is considered too risky.

The ADeSSSA approach transforms visual, acoustic, and RF data into a probabilistic model of imminent contact and subsequent collision free path planning for avoidance. This Sense and Avoid capability is paving the way to Beyond Visual Line-of-Sight (BVLOS) operation for SUAS, greatly expanding the utility of these platforms across the industry. The system is small enough for integration onboard even the smallest unmanned aircraft, but scalable for large cargo UAS and other advanced aerial mobility aircraft.

ADeSSSA’s objective is to equip sUAS with an advanced ability to detect and respond to aerial collision risks. This fills a need for UAS operators (including NASA and other US federal agencies) seeking to conduct advanced flight operations in mixed airspace. ADeSSSA can enable advanced regulatory waivers in a number of adjacent industries seeking to grow the UAS service sector by enabling autonomous sensing of aerial hazards during BVLOS flights. ADeSSSA could also address NASA’s interests in mixed airspace integration, Air-to-Air Mobility and Urban Airspace Mobility applications. The system’s modular deep learning based AI system combines visual, acoustic, and RF (ADS-B) modes of sensing in a modular package, taking advantage of the sophisticated sensors of today, but is also scalable to new sensor modalities in the future. More importantly, ADeSSSA leverages low-SWAPC components, making it an ideal bolt-on product to retrofit existing sUASs that don’t have sense and avoid capabilities.

About GreenSight, Inc. GreenSight’s industry-leading technology is developed and supported by a team with extensive backgrounds in robotics, autonomous vehicles, spacecraft, unmanned aerial vehicles (UAVs/drones), advanced communications and other forms of aerospace development as well as agriculture and land management.The GreenSight team has years of experience working with government offices and regulatory bodies both in the US and internationally. GreenSight’s automated drone based intelligence system operates daily over golf courses, farms and other facilities all over the world. GreenSight is a developer and manufacturer of drones, payloads and related components that integrate with its robotics platform. The company has conducted over 14,000 automated remotely managed SUAS flights in six countries. For more information on GreenSight or ADeSSSA please contact
