OVERVIEW
LYNX – Ultra-Compact ISR Payload with EO Zoom and IR Imaging
Gremsy introduces LYNX, its most compact and lightweight ISR payload to date, weighing just 190 grams. Engineered for small UAV platforms, LYNX features a distinctive spherical design that enhances aerodynamics and flight stability. Despite its minimal form factor, it integrates a high-resolution EO camera with up to 10x digital zoom alongside an infrared (IR) thermal sensor—delivering powerful dual-spectrum imaging for mission-critical aerial surveillance and reconnaissance operations.
