Product Overview
The Merak-G50ST is a discrete (split-type) fiber optic gyroscope module in a 50×50×30 mm, 160 g package for flexible OEM integration. It shares the electronics of the customer’s navigation system while delivering 0.1°/hr accuracy (100 s, 1σ) and ≥±400°/s dynamic range. RS-422 output up to 4000 Hz and 150,000-hour MTBF make it suitable for high-reliability embedded navigation products.
Key Features
- Accuracy of ≤0.1°/hr (100 s, 1σ) with ≤1°/hr in-run bias
- Ultra-compact 50×50×30 mm discrete module weighing only ≤160 g
- Output update rate up to 4000 Hz over RS-422
- Low power consumption of ≤3 W from a 5 V supply
- MTBF ≥150,000 hours per MIL-HDBK-217-F
- Operating temperature -40℃ to +70℃ with 20–2000 Hz, 6.06 g vibration screening
