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.

Applicable to coal mines, tunnels, and exploration! Northseeker's strength revealed

 

Under the surface, whether it is coal mining, tunnel penetration or geological exploration, accurate azimuth and orientation technology has always been the core guarantee of engineering safety and efficiency. North seekers are playing an irreplaceable role in these fields with their high precision and strong anti-interference characteristics.

Taking the north seeker ER-MNS-05Mini as an example, let’s understand how the north seeker works.

**Underground excavation**

The underground environment is complex, and deviations in the tunnel direction may lead to major safety hazards. Traditional measurement tools are easily affected by metal equipment and electromagnetic interference.

The north seeking accuracy of this north seeker can reach 0.25°secψ(1σ)! It can provide more accurate azimuth, pitch angle, roll angle and other attitude information. It not only has extremely high stability, but also is not affected by external interference and can be used in magnetic mining areas.

The shield machine is susceptible to interference from geological conditions and mechanical vibration during excavation. The guidance system integrated with the north seeker can correct the attitude of the shield machine in real time.

**Geological Exploration**

In geological surveys or tunnels passing through complex strata, it is necessary to accurately measure the direction of rock strata, fault directions, etc. The north seeker can provide a high-precision direction reference and can be used in conjunction with geological radar detection to ensure the accuracy of measurement data.

**Extreme size, flexible installation**

The size of ER-MNS-05 Mini is 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).

**OEM Customization**

It takes only a few simple steps to connect the product to your system and obtain the geocaching data without the 15-pin plug provided by our company. The size and weight of our products are significantly reduced by removing the base plate housing.

RTK signal is easily blocked? IMU makes RTK have unlimited possibilities

When you use an RTK surveying instrument to measure in some places with obstructions or requiring a large tilt, do you always encounter weak signals, no signals, or inaccurate measurements?

Now many RTKs are equipped with IMUs to make measurements more efficient and accurate. IMUs can maintain short-term relative positioning accuracy when RTK signals are blocked or temporarily ineffective. A separate external IMU can meet measurement needs more flexibly.

For example, an IMU ER-MIMU-12 can perfectly solve the above problems while improving measurement and stakeout efficiency!

**Excellent performance, automatic tilt compensation**

Equipped with a three-axis gyroscope and a three-axis accelerometer, the built-in gyroscope dynamic measurement range is ±400°/s, bias instability ≤1°/h, angle random walk <0.25°/√h; accelerometer dynamic The measurement range is ±30g and the bias stability is <50ug.

The IMU can be used to perform real-time interference-free and automatic tilt compensation on the RTK surveying instrument, and can perform measurements at large tilt angles. The IMU data is used to sense the device’s attitude changes (roll angle, pitch angle, and yaw angle) and perform tilt compensation.

It can ignore magnetic fields and can achieve accurate measurements even in difficult locations.

**Compact size, easy integration**

The 120mm x Φ30mm cylindrical IMU weighs ≤150g and is very portable.

In some measurement scenarios that require rapid deployment, the cylindrical IMU can be conveniently fixed on a tripod or measuring rod and can be put into use quickly without complicated debugging, saving time and costs.

**Quick initialization and accurate dynamic measurement**

RTK initialization time is long, IMU can significantly shorten the RTK initialization time. You can initialize the internal IMU by walking a few meters and easily start the measurement mode!

Even if the measuring rod is moved, tilted or leveled during measurement, there is no need for tedious calibration procedures and the measurement can be continued immediately while ensuring measurement accuracy.

IMU can make RTK measurement results more accurate, improve measurement efficiency, and expand the application scope of RTK surveying instruments, especially in environments with limited GNSS signals.

What is the biggest difference between Gyro Northfinder and gyro compass?

 North finder is a high-precision dual-shaft dynamic tuning gyro that can determine the true north direction value of the attached carrier by measuring the angular velocity of the earth's rotation. It is not affected by external magnetic fields or other environments. In addition, it can also be combined with acceleration for horizontal angle measurement and correction. The gyro north finder is mainly used for: radar, antennas, military vehicles, initial alignment and direction control.

The compass is a simple instrument used to determine the orientation. The main component is a magnetic needle that can be freely rotated on the shaft. The magnetic needle can be maintained in the tangential direction of the magnetic meridian under the action of the earth magnetic field. The north pole of the magnetic needle points to the geographic North, and this property can be used to identify the direction. It is commonly used in navigation, geodesy, travel and military affairs.

Since the structures and principles of the two types of gyro north-finding systems are different, they each have their own strengths. Therefore, based on the respective characteristics of these two types of devices, solutions can be complemented during research or use.

For example , MEMS north seeker(north finder) ER-MNS-06 (0.25°-1°) is our Smallest Size Triaxial MEMS North Seeker(north finder),and can be used in different areas where need small size north seeker(north finder).
