Understanding G400D Gyroscope Specifications
Selecting a MEMS gyroscope involves much more than comparing angular rate ranges. Parameters such as Angular Random Walk (ARW), Bias Stability, Bandwidth and Latency often have a greater impact on real-world system performance than the basic measurement range itself.
The Gladiator Technologies G400D was designed for demanding stabilization, navigation, guidance and motion control applications where low noise, high bandwidth and minimal latency are critical.
Angular Random Walk (ARW)
Angular Random Walk (ARW) is a measure of gyro noise and is typically expressed in °/√Hr. Lower ARW values indicate cleaner measurements and allow more accurate angle estimation over time.
For applications such as antenna stabilization, EO/IR gimbals, robotics and navigation systems, low ARW helps reduce jitter and improve overall pointing accuracy.
Bias In-Run Stability
Bias In-Run describes how much the gyroscope output drifts while the sensor is operating under stable conditions.
A low bias value improves long-term accuracy and reduces accumulated angular errors, especially in systems that must operate for extended periods without external position updates.
Bias Over Temperature
Environmental temperature changes can significantly affect gyro performance.
Bias Over Temperature specifies how much the sensor bias shifts across the operating temperature range. Lower values allow the system to maintain accuracy without requiring frequent recalibration.
The G400D is factory calibrated and temperature conditioned from -50°C to +85°C to provide stable performance across demanding operating environments.
Bandwidth
Bandwidth determines how quickly a gyroscope can respond to changes in rotational motion.
A higher bandwidth enables the sensor to accurately measure rapid movements and dynamic maneuvers. This is particularly important in stabilization systems, autonomous platforms and guidance applications where response time directly impacts performance.
The G400D supports bandwidths up to 600 Hz when configured with VELOX™ Plus processing.
Data Rate
Data Rate defines how frequently measurement data is transmitted from the sensor.
Higher data rates provide more detailed motion information and improve control loop responsiveness.
With output rates up to 10 kHz, the G400D is capable of supporting high-speed control systems and demanding real-time applications.
Digital Message Delay
Latency is often overlooked when comparing MEMS gyroscopes.
Digital Message Delay represents the time required for sensor measurements to be processed and delivered to the host system. Lower latency allows control systems to react faster and reduces phase lag within closed-loop stabilization architectures.
The G400D delivers message delays as low as 20 µs using VELOX™ Plus processing.
G Sensitivity
Gyroscopes are intended to measure rotational motion, but linear acceleration can also influence sensor output.
G Sensitivity quantifies this effect. Lower values indicate better immunity to vibration, shock and platform acceleration, improving performance in dynamic environments.
Scale Factor Error
Scale Factor Error describes how closely the sensor output matches actual angular motion.
Lower scale factor errors improve measurement accuracy and simplify system calibration, especially in precision navigation and stabilization applications.
Why These Specifications Matter
For many modern aerospace, defense and autonomous systems, performance is determined not by a single specification but by the combination of low noise, stable bias, high bandwidth and low latency.
The Gladiator Technologies G400D combines these characteristics in a compact 17-gram package, delivering tactical-grade MEMS gyroscope performance for demanding motion sensing applications.
