CAL Analytics Automated Collision Avoidance Technology Provides Scalable Solution for UAS Traffic Management

Beavercreek, OH – CAL Analytics recently tested a regional detect and avoid (DAA) system as a service capability for Unmanned Traffic Management (UTM) environments. The two-day demo showcased the technology’s ability to prevent collisions between unmanned aircraft and other airborne traffic in a variety of real-world scenarios.

CAL Analytics DAA service, powered by the FAA’s ACAS sXu software (Airborne Collision Avoidance System), enables the UAS to “see and avoid” using sensor and guidance technology that do not have to be equipped on the aircraft, thereby providing much needed relief to airborne equipage requirements. Until airborne DAA sensors can be matured to the point they provide affordable and reliable service, this scalable DAA service will provide much needed protections against airborne hazards for UAS to safely operate beyond visual line-of-sight (BVLOS) without ground observers.

“The successful flight tests are a key step to bringing routine commercial drone operations to a reality,” said Dr. Sean Calhoun, Managing Director of CAL Analytics. “By providing the UTM system-wide DAA as a service (without the need for onboard sensors), our cloud-based solution makes it easy for UAS service suppliers (USS) to provide automated DAA service with almost no overhead in any area with surveillance coverage.”

A key advancement of CAL’s DAA approach is the integration with a USS to receive real-time telemetry for the UAS and pass on DAA guidance commands for automated maneuvering. CAL partnered with AiRXOS (part of GE Aviation) to achieve this full representative integration. By working with the USS directly as the gateway to the UAS, the DAA system can scale as needed real-time based on demand.

“Surveillance, strategic deconfliction, and tactical deconfliction, i.e. DAA, are critical services to support a broad spectrum of advanced UAS operations including Beyond Visual Line of Sight (BVLOS), says Ted Lester, Chief Technologist, AiRXOS. In integrating CAL Analytics DAA-as-a-service with AiRXOS’ UAS Air Mobility Platform, the flight demonstrations show a clear path to safely operating BVLOS without ground observers that’s achievable now. AiRXOS is pleased to have helped perform this critical testing with CAL Analytics.”
Over the two-day live demonstration, CAL used telemetry, ground surveillance data from AiRXOS and SRC, Inc. to execute fully automated DAA guidance commands for both sUAS vs. sUAS and sUAS vs. manned aircraft. The integration of multiple UTM service providers provides system-wide layered deconfliction services including flight plan conflict detection and automated collision avoidance. 

“Our mission is to provide protection to the entire airspace, regardless of platform type or equipage restrictions,” said Josh Silbermann, ACAS sXu technical lead at the Johns Hopkins University - Applied Physics Lab supporting the FAA’s TCAS Program Office. “As we anticipate the introduction of automated and autonomous systems into the airspace, executing high densities of parallel critical missions, in order to maintain the level of safety that is expected of our national airspace, a robust DAA system needs to be at the heart of that airspace.”

Columbus, OH – CAL Analytics, in coordination with the Ohio Department of Transportation (ODOT), has launched a low-altitude air traffic management system for drones to support statewide operations. As the number of uncrewed aircraft systems (UAS), or drones, grows, a robust system for managing the low-altitude airspace where these aircraft operate is necessary to ensure safety. While the Federal Aviation Administration (FAA) provides air traffic control for traditional aircraft flying in certain airspaces, low-altitude traffic management for drones is the responsibility of individual operators. Currently, drone pilots are required to keep the aircraft within sight to avoid a collision. A UAS Traffic Management (UTM) system enhances safety by enabling sharing of flight details between UAS operators, providing a digital tool for flight planning, and allowing operators to eventually operate beyond visual line of sight (BVLOS) while continuing to minimize the risk of collision. “The introduction of this vital capability continues Ohio’s tradition of innovation in the aviation community while prioritizing safety,” said Rich Fox, director of the Ohio UAS Center at ODOT. “As we collaborate with others at the newly opened National Advanced Air Mobility Center of Excellence, we expect this to be the first of many industry-leading activities coming out of that state-of-the-art facility.” Following several state sponsored research efforts to determine the best way to develop and deploy traffic management for uncrewed aircraft in Ohio, this system, implemented by CAL Analytics, provides interoperability where any user can enroll to share and receive flight information. As drone technology continues to advance, traffic management will be a key enabler of BVLOS operations, which currently require special permission from the FAA once stringent safety requirements are met. “We couldn’t be more thrilled to continue our collaboration with ODOT by deploying this discovery and synchronization services to fully realize this first of a kind operational UTM capability throughout the state of Ohio,” said Dr. Sean Calhoun, managing director of CAL Analytics. “This realization is the result of a lot of industry development, including the essential work from The Ohio State University research team and sponsored research from the Ohio Federal Research Network (OFRN). We are looking forward to working with the various interested stakeholders throughout the state and the FAA to learn from this system and to start scaling UAS operations throughout Ohio.” ODOT and the City of Hilliard will be the first organizations to enroll in the system and begin exchanging information as they look to leverage UAS as a tool for everything from inspection and traffic monitoring to onsite situational awareness for first responders, such as police and fire department dispatches. “Hilliard is excited to leverage this and other airspace services that Ohio has established to enable our first responder drone operations” says Deputy Police Chief for Hilliard, Ron Clark. “These services will be critical for us to achieve FAA approval and operate our drones in a safe and effective manner.” In the coming years, more advanced and BVLOS drone operations will increase in Ohio, which means multiple operators may be flying in the same area to deliver medical supplies, perform emergency services, conduct infrastructure inspections, and even deliver commercial packages. For safe and successful scaling of commercial drone operations, it’s imperative that pilots have situational awareness for strategic deconfliction. While both private and public organizations can enroll in the traffic management system, this resource is particularly valuable for other state agencies and local governments across Ohio. These services are available at no cost to any operator or fleet manager that requests access and goes through the onboarding process.

Columbus, OH – CAL Analytics has been awarded a NASA Phase II-E Small Business Innovation Research (SBIR) award to deploy their Health & Integrity System (HIMS) to the Ohio Department of Transportation’s Uncrewed Traffic Management (UTM) system. This will be the first-time an In-time System-wide Safety Assurance (ISSA) system will be deployed and integrated into a functioning UTM environment for operations in an urban environment. This initiative is researching ways in which the resiliency and robustness of UTM ecosystems can and should be improved. The primary result of those activities was the formulation of a flexible, service-based architecture for Health & Integrity (H&I) monitoring, assessment, and mitigation of complex, federated System of Systems (SoS). This aptly named Health & Integrity Management System (HIMS) adds another dimension of capability to the UTM architecture wherein it is intended to holistically monitor and respond to the ecosystem, providing continuity between independent UTM services from a system reliability perspective “Being able to evaluate our ISSA implementation in an operational environment that Ohio offers will be a critical step for validating the our various HIMS safety monitors and system interactions what will be key to ensuring a robust UTM ecosystem for safe low-altitude operations,” said Dr. Sean Calhoun, Managing Director of CAL Analytics. “Our HIMS system not only provides various real-time monitoring of key systems, such as surveillance and navigation, but we also provide capabilities assessing the impacts to operations and how to relay that information to operators.” The CAL HIMS system builds off the Resilienx, Inc. FRAIHMWORK platform to realize a scalable ISSA system tailored specifically to UTM applications. The open architecture approach to the ISSA system enables seamless integration of future system monitoring and scalability. The effort builds off Ohio and NASA’s existing AAM National Campaign partnership, which includes System-Wide Safety, and The Ohio State Universities UTM development effort sponsored by the Ohio Department of Transportation (ODOT). “Safety is the number one goal at the Ohio Department of Transportation, operational assurance is the most important component in any aviation operation. As we continue to move towards highly automated and remote operations in the airspace, the health of systems and sensors providing information becomes crucial to maintain the safety for transportation on the ground and in the air,” said Fred Judson, UAS Director – Ohio UAS Center for ODOT. “Safety is the key to innovation in aviation. Learning how and when to automate our safety monitoring, assessment, and mitigation functions enables us to design air systems that benefit all of us.” said Dr. Misty Davies, NASA’s Project Manager for System-Wide Safety Project.
