Why is this north Seeker your best choice in the drilling field?

 


During downhole operations, the main problems that the north seeking system needs to solve include impact vibration, system volume, azimuth accuracy, and downhole temperature. Considering the measurement requirements at a certain depth, the north seeker needs to be equipped with an efficient thermos bottle. The fiber optic north seeker is expensive, and its volume increases with the increase in accuracy, which greatly limits the drilling and logging equipment. In general, the north seeker needs to be installed on the guide rail of the drilling rig or on a stable plane during drilling. At the same time, it is necessary to ensure that the axis of the north seeker is consistent with the axis of the drilling rig.

But with ERICCO's MEMS North Seeker (ER-MNS-09), these problems can be easily solved. Why should we choose it?

1. New appearance, high precision: The new cylindrical north seeker tailored for this field has a diameter of only 30mm, a small size, and is easy to install in a thermos bottle, meeting the application requirements of ordinary standard cased wells, drill pipes and small well diameters.

2. Different installation positions: The special shape enables it to be placed in the probe of the drilling rig, which is more accurate than other north seekers. It can provide strong support for users to solve information such as azimuth and attitude angle. It helps drilling engineers to accurately control the trajectory of the drill bit and ensure that the drilling operation is carried out in the predetermined direction.

3. Different accuracy for you to choose: There are three models in this series (ER-MNS-09A, ER-MNS-09B, ER-MNS-09C) with north seeking accuracy of 1°secψ(1σ), 0.5°secψ(1σ), and 0.25°secψ(1σ) respectively, which can be selected according to different needs.

4. Strong and durable, resistant to high impact and vibration.

5. Adopting MEMS technology, the cost is lower, but the high performance is not compromised.

Choose a suitable IMU to make your drone flight more stable and safe

 


       As one of the core components of drones, IMU plays an irreplaceable role. Its high precision, fast response and freedom from external interference enable drones to maintain stable and precise flight and accurate navigation and positioning in complex environments, and can also perform fault diagnosis for drones. ERICCO's MEMS IMU can achieve high performance while being small in size and light in weight, making it very suitable for drones.

We have a tactical-grade IMU ER-MIMU-M02, which is low-cost and has an advantage in price. It is a 10-axis IMU with an added three-axis magnetometer and barometer (altimeter). It is only 47×44×14mm in size and weighs 50g. Compared with other IMUs, it is more suitable for drones.

The built-in accelerometer of the IMU cannot be used to detect absolute heading (yaw). The magnetometer in this IMU measures the magnetic field strength in three dimensions, which can help determine the heading of the object as well as roll and pitch, and correct the integrated error of the yaw gyroscope in the sensor fusion algorithm.

The barometer measures the atmospheric pressure and calculates the altitude of the drone, which is crucial for the safe flight of the drone!

The dynamic measurement range of the built-in gyroscope is ±450º/s, the bias instability is 2 º/h, and the angular random walk is 0.08º/√h. The dynamic measurement range of the accelerometer is 16g, the bias stability is 0.1mg (Allen variance), and the angular random walk is 0.02m/s√h.

Considering the flight time requirements of drones, this IMU has a power of only 1.5W, which can extend the flight time of drones.

This IMU has a short production cycle and can be mass-produced, which is particularly suitable for users with large demands and limited budgets.

Do you know what can make drone flights more stable, safer and more widely used?



The key to achieving autonomous navigation, stable control and precise flight of drones is closely related to IMU, which is one of the core technologies of drone systems. At present, there are also research teams that have developed IMU-centric data-driven diagnostic methods to perform fault diagnosis on drones without the need for additional sensors. Choosing the right IMU can make flight more stable and safer.

ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (OEM customization is available) can be used in drones. Using MEMS technology, they are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, and are very popular among users.

Drones have strict requirements on the size and weight of IMUs. The ER-MIMU-03 has a size of (43.2×43.2×35.5mm (without shell), 65×70×45.5mm (with shell)) and a weight of (≤100g (without shell), ≤220g (with shell)).

The ER-MIMU-07 is a very small IMU, measuring only 38.6 x 44.8 x25.5mm and weighing less than 70g, which is suitable for drones with higher IMU requirements.

Flight control of drones is one of their most basic functions. MEMS IMU helps drones maintain a stable attitude by providing real-time acceleration and angular velocity data.

The gyroscope measurement range of ER-MIMU-03 and ER-MIMU-07 is ±400deg/s, bias instability <0.3deg/hr, angular velocity random walk <0.15°/√h, accelerometer bias repeatability 5mg, and second-order nonlinear coefficient <100μg/g2. At the same time, it has the characteristics of low power consumption, which prolongs the flight time of drones.

It can also combine data from other sensors (such as GPS, magnetometer, etc.) to calculate the precise location and attitude information of the drone for navigation and positioning. When the drone is taking aerial photos, it can maintain extremely high stability to ensure the clarity and stability of the images and videos taken. At the same time, it can also be used as part of the drone's fault safety system to detect abnormal movements or attitude changes and trigger automatic recovery procedures or emergency landing procedures to protect the safety of the drone and the surrounding environment.

In the design and application of drones, high-performance IMUs are able to provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements, and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.

MEMS IMU has many applications in the field of drones. They not only improve the performance and stability of drones, but also expand the scope of application of drones.
