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.

The smallest North Finder you've ever seen

 The dimensions are only 44.84×38.88×21.39mm and the weight is 60g. The north-seeking accuracy can reach 0.25°~1°, and the update rate is 200Hz. It has the advantages of high precision, light weight and low power consumption, and can quickly and independently determine the true north direction. Compared with other MEMS north seekers, it not only improves the sensitivity of the sensor and reduces errors, but also makes its power supply only support 5±0.25V and the power is 2W. The MEMS gyroscope used has a bias instability of 0.02°/hr and an angular random walk of 0.005°/√hr, which can meet the needs of medium and high-precision measurements, and is small enough for devices with high space and power consumption requirements.

It can be used in directional drilling rigs and deep hole drilling rigs, which can help find the true north direction in coal mines, improve work efficiency, and tunnel boring machines in coal mining to improve the quality of coal mining.

At the same time, it can also be used in radar vehicles and military rocket launch vehicles, which is very helpful in improving the orientation and alignment of rocket launches.

In the field of surveying and mapping vehicles, it can be directly installed on the surveying and mapping vehicle. For static north seeking, you can choose the 01 model for high-precision dynamic north seeking.

Rock drills and tunnel construction can also apply north-seeking technology.

It is not only widely used in high-tech defense fields such as satellites, missiles, and high-precision inertial navigation system initial alignment, but also widely used in geophysical exploration, coal mining, geodesy, mining, underground drilling projects, tunnels and other fields. Excavation, as well as civilian fields such as unmanned vehicle automatic driving systems and vehicle positioning and navigation systems.

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).

Classification of North Finder

 

North finder is a compass, is used to find the north direction at a position value. Gyro north finder, also known as gyrocompass, is an inertial measurement system based on the principle of gyroscope to determine the earth’s rotation rate in the horizontal projection direction of the earth. Its north seeking process does not require external reference. In addition to the high latitude limit, it is not affected by weather, day and night, geomagnetic field and site pass conditions. Gyroscope is a kind of precision inertial measurement instrument, which is used to provide directional reference for artillery, surface-to-surface missile and ground radar and other mobile weapon systems.According to the type of gyro used, gyro finder can be divided into the following three types:

1.A north seeker with two degrees of freedom gyroscope as a earth rotation sensor (such as hanging pendulum gyro    north seeker)

2.A north seeker with a uniaxial rate gyroscope as a sensor (such as a strapdown gyro north finder)

3.Platform north seeking system

Fiber optic gyroscope is a kind of high precision inertial instrument, which can be used to indicate the orientation of the carrier and the true north direction.Use of fiber optic gyroscope measured rate of the earth from the Angle of value and the measured gyroscope and accelerometer horizontal plane Angle, through the computer solution can be obtained in the baseline and the true north direction Angle, placed on the baseline of the accelerometer find north finder attitude Angle can be detected.
