✈️Flight safety secrets: The core role of high-precision IMUs in aviation

 

✨ High-precision IMU plays an irreplaceable role in the aviation field. It provides key data support for the flight control system (FCS) by providing the acceleration and angular velocity of the carrier, and combining algorithms to solve attitude, speed and position information.
✅ Take a high-precision IMU ER-MIMU-02Mini as an example for analysis.
✅ In the flight control system, the data provided by IMU is the basis for the autopilot to achieve precise control. The autopilot continuously adjusts the flight parameters of the aircraft based on the data of IMU to ensure the stability and safety of the flight process.
๐Ÿ”ท Excellent precision performance ๐Ÿ”ท
๐Ÿ‘‰ Gyroscope bias instability is 0.03deg/hr, and angle random walk is <0.01 °/√h; accelerometer bias repeatability is 100ฮผg, and class II non-linearity coefficient is <100ฮผg/g². 400Hz high-frequency data output, power consumption as low as 2W.
๐Ÿ‘‰ Such high-precision measurement capabilities can accurately measure the attitude changes of aircraft in aerial photogrammetry. Using the information provided by IMU, the captured images can be accurately geometrically corrected and positioned.
๐Ÿ‘‰ This makes the drawn maps more accurate and can meet the needs of high-precision geographic information in urban planning, land surveying, geological exploration and other fields.
๐Ÿ‘‰ In the aircraft's navigation system, the high-precision IMU cooperates with other navigation equipment to form a navigation system. When the GPS signal is interfered with or fails, this IMU can switch to the main navigation data source in a short time to ensure that the aircraft's navigation system continues to provide accurate position and attitude information.
๐Ÿ”ท Compact and lightweight design ๐Ÿ”ท
๐Ÿ‘‰ Adopting modular design, the size is only 40*40*42 (mini version with shell)/27*26*34 (mini version without shell and baseboard), and the weight is 80g (mini version with shell)/ 40g (mini version without shell and baseboard).
๐Ÿ‘‰ This compact and lightweight design is crucial for the aviation field, which is extremely sensitive to weight and space. It can effectively reduce the load of equipment such as drones and aircraft, and improve flight performance and efficiency.
๐Ÿ”ท Powerful integration and compatibility ๐Ÿ”ท
๐Ÿ‘‰ It can be customized by OEM, has good integration and compatibility, and can be easily integrated into various systems.
๐Ÿ‘‰Simple operation can connect to the system and obtain IMU data. At the same time, by removing the baseboard shell, the size and weight of the IMU can be greatly reduced.

For drones, the choice of IMU is related to drone performance. Indicators such as accuracy, stability, and compatibility are all very critical. As the “nerve center” of drones, how does IMU enable flight?

Take a nine-axis IMU ER-MIMU-07 as an example, which has a built-in three-axis gyroscope, three-axis accelerometer, and three-axis magnetometer. The measurement data is transmitted to the flight control system to obtain information such as the attitude, speed, and displacement of the drone.

**The secret of wind-resistant flight and high-definition aerial photography**

The built-in gyroscope has a measurement range of 400ยบ/s, bias instability <0.1 ยบ/h, and angle random walk <0.05°/√h. The accelerometer measurement range is 30g, bias stability is <50ug, and bias repeatability is 100ug.

The data provided by the IMU can monitor the pitch, roll, and yaw attitude of the drone in real time. When the drone encounters strong winds or sharp turns, the real-time data of the IMU will trigger the flight control to quickly adjust the motor speed. Ensure stable flight and silky smooth shooting without shaking.

**Small and lightweight: flexible installation**

This IMU is only 38.6x 44.8 x25.5mm in size and weighs ≤70g, so it can be easily installed in various fuselage spaces.

**Better performance, lower price**

It has better performance than STIM300, but at a lower price, helping drones reduce costs.

       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.
