Not subject to environmental restrictions, MEMS north seekers help various fields achieve high-precision orientation

The north finder can determine the true north direction through the rotation of the earth, and can provide an orientation reference for various activities. It is not limited by weather, location and magnetic field environment conditions, and has the characteristics of high accuracy, high reliability and easy maintenance.

ERICCO’s MEMS north finder ER-MNS-05/05mini can be integrated into various equipment systems that require orientation and alignment. There are many application areas, such as: determining the drilling direction, tunnel construction, direction pointing and tracking of satellite antennas, orientation in surveying and mapping systems, precision platform measurement and control, etc.

This north finder has the following main advantages:

**Small size, high-precision north seeking**

The size of ER-MNS-05 is 70*65*45mm, and the weight is <220g. Currently, ER-MNS-05 Mini is also launched, with a size of 40*40*42mm and a weight of <120g.

The highest north finding accuracy of MEMS north finders on the market is only 1°secψ(1σ) or 0.5°secψ(1σ). But our MEMS north seeker’s north seeking accuracy can reach 0.25°secψ(1σ)! Provide more accurate north information.

It can also provide users with pitch angle and roll angle information, becoming a powerful assistant for engineers.

**OEM customization**

Connect the product to your system and acquire data in just a few simple steps, without using the 15-pin plug provided by our company. By removing the baseplate casing, the size and weight of our products can also be significantly reduced.

**Resistant to harsh mechanical environments**

From the beginning of its design, this north seeker fully considered the complex and changeable working environment. The unique design of the inner platform gives the product extremely high stability and reliability, and it can maintain excellent performance even under harsh conditions of high impact and strong vibration.

**Easy to Repair**

The internal design of this north seeker allows the gyroscope and accelerometer on the PCB to be directly replaced and repaired, making it easier to repair than other north seekers.

A powerful assistant for mining and drilling

 Installed near the drill bit, high-precision IMU for real-time and accurate drilling measurement

In drilling projects, compasses are often used to find the north, but compasses can produce large errors under magnetic field interference. Traditional inclinometers cannot achieve real-time continuous dynamic measurement of the drilling tool attitude. At the same time, the measurement position is far away from the drill bit, and the measured information has errors, which affects the entire drilling process.

We have an IMU ER-MIMU-09 that can be directly installed in the drill pipe and used in gyro tools or HDD tools. After adding algorithms, it can perform measurement while drilling, and obtain information such as the true north direction and the attitude and speed of the drill tool through calculation. It is not subject to any external interference and the measurement results are accurate.

**Near-bit installation**

The cylindrical shape design is 120mm long, only 30mm in diameter, and weighs less than 150g. It can be placed directly near the drill bit or in the drill rig probe. The measurement accuracy is improved, and the position and attitude of the drill bit can be understood more accurately, ensuring the safety and efficiency of drilling.

**High precision, high performance**

Built-in high-performance three-axis MEMS gyroscope and three-axis accelerometer. The built-in gyroscope bias instability is 0.01deg/hr, and the angular velocity random walk is 0.0025°/√h. The accelerometer bias stability is 50ug, and the bias repeatability is 100ug.

The measurement data provided can provide support for solving information such as azimuth and attitude angle.

**Real-time and dynamic response**

The measurement data output by IMU in real time can provide support for real-time monitoring of the drill bit's attitude changes and respond quickly to emergencies during drilling.

**Strong environmental adaptability**

We also have high-temperature IMUs with an operating temperature of -40℃~+125℃. The low-power design can also effectively resist adverse factors such as vibration, impact, magnetic field interference and high temperature during drilling.

It can be used in gyro tools and HDD tools for logging, drilling, and directional drilling.
