Product Overview
The Merak-G50S is a compact integrated fiber optic gyroscope (IFOG) delivering tactical-grade performance with 0.1°/hr accuracy (100 s, 1σ) and a dynamic range of ±400°/s. Its Φ50 mm × 19 mm package weighing under 500 g fits tightly integrated navigation and stabilization systems. RS-422 output at up to 2000 Hz and a 10 s turn-on time make it a drop-in sensing core for AHRS, INS and pointing-stabilization applications.
