Aurora Flight Sciences, a Boeing Company, recently completed a project to advance the capabilities of its Modular Intercept Drone Avionics Set (MIDAS) counter-unmanned aircraft system.
According to a press release, Aurora engineers designed, implemented, and tested improvements to the drone engagement device and onboard autonomy, as well as to the speed and maneuverability of the vehicle platform. Using similar test parameters to last spring’s demonstration for the Joint Counter-small Unmanned Aircraft System Office and the Army Rapid Capabilities and Critical Technologies Office, MIDAS autonomously defeated 83% of small UAS targets.
“Since our successful customer demos last year, we’ve continued to improve hardware and software systems on MIDAS to ensure we are prepared to meet the needs of future counter-sUAS programs,” said Jason Grzywna, director of small UAS programs at Aurora. “The vehicle we used for the most recent tests included enhancements in agility and autonomy, which improved target acquisition, and in the bolos fired by the DED, which proved more effective in completely disabling the target.”
Originally developed under a Defense Innovation Unit (DIU) contract, MIDAS is designed specifically to mitigate adversary sUAS with low collateral effects. Cued by ground radar, the multi-rotor, AI-enabled MIDAS uses an on-board sensor to autonomously identify and track adversary targets. Once the target is identified, MIDAS fires bolo projectiles that entangle the target’s propellers and disable the vehicle without endangering bystanders.
Part of the vehicle’s autonomy includes the use of perception and guidance, navigation, and control (GNC) algorithms to search for, track, and target drones within range of the vehicle’s perception sensors. These algorithms provide a localized position of the target in real time and determine how the system develops its autonomous intercept and firing solution. The vehicle then uses the information from these algorithms to provide control commands directly to the autopilot system and fire the drone engagement device.
The use of perception capabilities on MIDAS is just one example of Aurora’s expertise in autonomy. For over 30 years, Aurora has been an industry leader in autonomous capabilities including human-machine teaming, GNC, and early-stage technology development.
