Key Features
Accuracy & Stability
The unit provides exceptional attitude measurement over time, with zero bias stability as low as 0.002 °/h (1σ, 100s). It maintains repeatable performance across a broad temperature range (-40℃ to +65℃), with full-temperature zero bias repeatability within 0.05°/h. The device also features a random walk coefficient below 0.001°/√hr, ensuring reduced signal noise and high data integrity.
Built for Demanding Conditions
Mechanical testing confirms that the device maintains consistent operation in harsh environments. Under random vibration (20Hz to 500Hz, 15 minutes per axis), the variation between average zero bias before and after vibration remains under 0.05°/h. The unit also withstands 30g mechanical shocks (half sine wave, 10ms), with zero drift changes under 0.02°/h, making it highly reliable for dynamic use cases including onboard and aerial platforms.
Rapid & Robust Communication
The G-F120H supports RS-422 bidirectional serial output, with data rates up to 460.8kbps for high-speed communication. Each transmission includes 32-bit gyroscope readings and 14-bit temperature information, with parity checking to maintain data accuracy and real-time delivery.
