What is a gyroscope used for?

 

A gyroscope is a sensor used to measure angular velocity. Its core function is to sense the rotational motion and attitude changes of an object. It can be applied to various fields that require navigation, positioning or stable control.

ER-MG-057, as a high-performance single-axis MEMS gyroscope (angular velocity sensor), has become an ideal choice for many professional fields due to its excellent performance and reliable design.

ER-MG-057 - Born for precise navigation and stable control in harsh environments

**Precise measurement and stable output**

Wide range: ER-MG-057 has a wide range of measurement up to ±400°/s, which can meet the angular velocity monitoring needs of various dynamic scenes, covering high-speed rotation scenes (such as drone maneuvers and high-speed operation of robotic arms).

Excellent stability: tactical-level high precision, zero bias instability as low as 1°/hr, angle random walk (ARW) 0.2°/√hr, 0.1dps ultra-low noise, 200Hz bandwidth combined with 2kHz data output rate, real-time capture of instantaneous angular velocity changes, and response delay of only 2ms.

**High integration and high reliability**

Ceramic LCC surface mount package, with airtight packaging to protect the core MEMS structure, is only 11x11x2mm in size, easy to integrate into various systems, and RoHS certified.

Supports 5V (4.75~5.25V) power supply, power consumption is only 35mA, with low power consumption, default internal synchronization mode, optional external synchronization, compatible with multi-system architecture.

Can work stably in strong shock (12g RMS) and vibration (1000g 5ms 1/2 sine wave) environment, suitable for high vibration scenarios such as aviation drones and unmanned vehicles.

**Application scenarios**

Navigation and positioning: suitable for scenarios such as inertial navigation system (INS), drones and autonomous driving. Combined with accelerometers, position, speed and direction are calculated by measuring the angle change and acceleration of movement.

Precision instruments and stabilization systems: Ensure precise control and attitude stability of mechanical movement, and improve the real-time and accuracy of target tracking.

UAV/aircraft stabilization: Provides data for the flight control system to sense the attitude changes (pitch, roll, yaw) of the aircraft, so that it can adjust the motor speed to keep the aircraft hovering steadily or flying according to instructions.

Ship/vehicle stabilization system: Large ships use gyro stabilizers to reduce roll; provide reliable attitude data support for autonomous driving.

Robot balance and control: Help robots sense tilt angles and maintain their own balance and motion control.

🛩️ The "Heart" of UAV Performance - Why IMU is Important?

 

✨ For drones, precise attitude control, stable flight performance, and real-time dynamic response capabilities are key. The core of drones relies on the accuracy and reliability of the inertial measurement unit (IMU).
✅ Take a nine-axis IMU ER-MIMU-07 as an example for analysis. It has a built-in three-axis gyroscope, three-axis accelerometer, and three-axis magnetometer. Combining excellent performance and ultimate cost-effectiveness, it is the first choice for drones. The measurement data is transmitted to the flight control system to obtain information such as the attitude, speed, and displacement of the drone.
🔷 Wind-resistant flight and aerial photography 🔷
👉 The built-in gyroscope has a measurement range of ±400º/s, bias instability <0.1 º/h, and angle random walk <0.05°/√h. The accelerometer has a measurement range of ±30g, bias stability <50ug, and bias repeatability of 100ug.
👉 The real-time feedback of the data measured by the IMU allows the drone to perform stable flight, precise hovering, flexible steering and other actions according to the instructions. The flight control system can monitor the pitch, roll and heading of the drone in real time.
🔷 Lightweight design releases the potential of drones 🔷
👉 The volume is only 38.6×44.8×25.5mm, and the weight is ≤70g, which can be easily installed in various fuselage spaces.
🔷 Compared with STIM300: Double Surpass of Performance and Cost 🔷
👉 Excellent Performance: With better performance, the drone can always maintain accurate flight, whether it is surveying, inspection or filming, it can perfectly complete the task.
👉 Strong Stability: Industrial-grade reliability, can work stably in the temperature range of -40℃ to 80℃, baud rate is 230400~921600, supports 400Hz data refresh rate, and real-time feedback without delay.
👉 Cost advantage: While ensuring high performance, the price is lower than STIM300. For drone manufacturers and enthusiasts, this means lower production costs and usage thresholds.

       GNSS satellite refresh rate is low and the signal is easily blocked or interrupted, resulting in GNSS signal loss. The integrated navigation system of GNSS+INS can make up for these problems, and the high-precision INS can keep working in a short time when GNSS loses lock.

GNSS+INS combined navigation is widely used in large unmanned aerial vehicles, mobile mapping, geographic information collection, urban intelligent transportation and other applications due to its sustainable navigation, high precision and high autonomy.

Our integrated navigation ER-GNSS/MINS-01 has ultra-high precision at the surveying and mapping level. It can provide continuous and high-precision position, velocity and attitude (roll, pitch and yaw) information.

**Mapping-level high-precision navigation**

The integrated navigation information provided has a roll and pitch accuracy of up to 0.01° and post-processing of 0.004°. The heading can reach 0.05°, 0.01° after post-processing, and the speed accuracy can reach 0.03m/s.

Supports RTK positioning, can automatically identify RTCM, and enter RTK state.

In the case of RTK interruption for 30 seconds, the roll and pitch accuracy can be maintained at 0.01°, and the heading accuracy can be maintained at 0.01°. The position is maintained at 0.2m and the height is maintained at 0.08m.

**High-precision core components**

Built-in high-performance navigation-grade MEMS gyroscope and accelerometer, the gyroscope measurement range is ±200°/s, and the bias instability is <0.02°/h. The accelerometer measurement range is ±60g, and the bias instability (Allen curve) is <2ug.

**Full-band full-system**

The built-in dual-antenna positioning and orientation GNSS module supports all major global satellite navigation systems (GPS/BDS/GLONASS/Galileo/QZSS), and can perform high-precision and rapid positioning and orientation. At the same time, it is compatible with all frequency points, and can obtain the best positioning effect at any location in the world.

The built-in satellite receiver has strong anti-interference ability, can still provide accurate positioning in complex electromagnetic environments, and also supports a variety of communication interfaces.

**Small size and light weight**

The size is only 65×70×45.5mm, the weight is less than 300g, and the aluminum alloy shell is used to ensure reliability. And the operating temperature range can reach -40°C to 80°C, which is suitable for most working environments.
