# GENERAL

## 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.
