Polish particle-velocity acoustic specialist (similar tech class to Microflown). Acquired by Quantum Systems (Bavaria-based ISR-drone maker) in February 2025. Now integrated onto Quantum's ISR drone platform for airborne acoustic detection and artillery ranging — a different deployment vector than ground-based arrays.
