For a defense OEM developing the next generation of its drone platform, ALTEN Technology led a ground-up redesign of the vehicle architecture intended to refine and sustain the current product offering while accelerating development, de-risking key subsystems, and supporting regulatory and export readiness. Their comprehensive approach combined requirements development and management with a full redesign of the chassis, legs, arms, deployment interfaces, radio interface, payload interfaces, sensor packaging, and battery charging system, supported by custom PCBA radio interface boards taken from schematic through layout and routing, flight controller and MCU development, and verification method planning. Key activities spanned the arms and chassis, a swappable radio bay, a redesigned architecture targeting design for manufacturing and cost reduction, battery enclosure and BMS integration, canopy design, and CE marking certification with export support. Based in Denver, CO, the 15-person team drew upon expertise in Electrical, Software, Mechanical, Systems, and Quality Engineering and Project Management, leveraging tools such as Altium, Zephyr, SolidWorks, UAVCAN, DroneCAN, and Cameo.
