What does a gyroscope mean for a drone?

In the wave of rapid development of drones, accurate, stable and reliable attitude perception is the key to achieve autonomous flight, complex maneuvers and environmental adaptation. The gyroscope measures the angular velocity of the drone around the X, Y, and Z axes in real time, and is the core input for the flight control system to perform attitude calculation and attitude stabilization control.

ER-3MG-103 MEMS three-axis gyroscope is becoming an ideal choice for drones due to its excellent performance and miniaturized design.

Miniaturization and Lightweight

Using the latest MEMS gyro technology, the thickness is compressed to 14mm, only 47×44×14 mm, which is easy to integrate into drones or small airborne devices with limited space or height. Weighing 40g, it has minimal impact on the payload and endurance of the drone.

High Precision and Stability

The bias instability <0.1 °/hr, which significantly reduces the cumulative error during long-term flight and improves the accuracy of hovering and track tracking.

Angle Random Walk (ARW) <0.05 °/√h, effectively suppressing random noise in attitude solution and improving the stability of the flight control system in a disturbed environment.

Excellent dynamic response

The range is ±400°/s, and the data update rate is 400 Hz. It can quickly capture the high-speed maneuvers of the drone, provide high-frequency, real-time angular velocity feedback for the flight control algorithm, and improve the controllability and stability of the aircraft in strong winds or rapid turns.

Strong environmental adaptability

Wide operating temperature range: -45℃ to +85℃, adapting to extreme flight environments such as severe cold at high altitudes and scorching heat in deserts.

Low power consumption design: Optimized for drone platforms that are sensitive to power consumption to extend flight time.

The ER-3MG-103 MEMS three-axis gyroscope combines the advantages of high precision, small size, light weight, wide temperature range, and low power consumption, perfectly meeting the high requirements of modern drones for attitude perception core sensors.

Its excellent bias instability, angle random walk and dynamic response performance provide solid technical guarantees for drones to achieve precise hovering, stable flight, rapid maneuvering and reliable navigation.
