Product Overview
The Merak-G70STR1 is a high-precision discrete fiber optic gyroscope providing 0.008°/hr accuracy (100 s, 1σ) and 0.003°/√hr angular random walk in a 70×70×32 mm module. The split-type architecture lets integrators place sensing heads remotely from their electronics, easing thermal and mechanical design. It is the sensing core of the Merak-H04/M04/L04 AHRS and INS products.
