🛩️ 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.

✈️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.

Excellent precision performance

Gyroscope bias instability is 0.03deg/hr, and angle random walk is <0.01 °/√h; accelerometer bias repeatability is 100μg, and class II non-linearity coefficient is <100μg/g². 400Hz high-frequency data output, power consumption as low as 2W.

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.

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.

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.

Compact and lightweight design

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).

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.

Powerful integration and compatibility

It can be customized by OEM, has good integration and compatibility, and can be easily integrated into various systems.

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.

New tools for drilling, well logging and mining, don’t you know about it yet?

 

In the fields of directional drilling, logging and mining, accurate control of direction and attitude is the core of successful operations. The complex industrial environment makes traditional sensors helpless. A new type of north seeker has become a tool for technological innovation with its unique advantages. Today we’ll take a closer look at why it’s essential for jobs in these fields.

**Break through space limitations: special-shaped design for easy installation**

Traditional inclinometers and MWD systems are installed at a certain distance from the drill bit, causing measurement errors; The cylindrical north seeker ER-MNS-09 adopts a compact design of 120mm × Φ30mm and weighs ≤150g. It can be directly embedded in the drilling rig's probe pipe and installed close to the drill bit.

This design is particularly suitable for oil logging tools (such as gyro tools, HDD tools) and TBM, significantly reducing measurement errors.

**Industry-leading accuracy: 0.25°secψ north-seeking accuracy**

In magnetic mining areas or deep well environments, magnetic field interference often leads to azimuth measurement deviations. The north seeker achieves true north orientation based on a three-axis MEMS gyroscope and accelerometer, with an accuracy of up to 0.25°secψ (1σ), far exceeding similar products on the market (generally 0.5°~1°secψ). The measurement error of the azimuth is controlled within a very small range.

Attitude tracking can be performed: output pitch, roll, and azimuth data to provide adjustment basis for drilling rigs or mining equipment. Initial attitude calibration and true north orientation are automatically completed in 5 minutes, greatly shortening the deployment time.

**A reliable partner in harsh environments: shock resistance, wide temperature range, and long battery life**

The operating environment of the oil and mining industry is extreme. The high-temperature version of the north seeker has an operating temperature of 5~125℃, which is suitable for high-temperature environments in deep wells; it can withstand strong shocks and vibrations during drilling to ensure continuous and stable data; it only requires 2W power and supports 6~12V wide voltage input, which is suitable for long-term continuous operation.

**Why choose a cylindrical north finder? **

Technological breakthrough: breaking the monopoly, the performance is comparable to that of a fiber optic gyroscope, and the cost is reduced;

Customized service: providing different accuracy and different temperature versions, normal temperature version (5~55℃) and high temperature version (5~125℃), to adapt to different operational needs;

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 400º/s, bias instability <0.1 º/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.
