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.

Is there an error in drilling trajectory control? The north finder installed near the drill bit makes drilling more accurate!

 Directional well technology is one of the most advanced drilling technologies today. Based on actual cases, the main problem of directional wells is the control accuracy of the trajectory. The directional tool will deviate from the trajectory and the measurement error is large. There is also a trajectory prediction error caused by the MWD being a certain distance away from the drill bit.

We have developed a new cylindrical north seeker ER-MNS-09 to address these problems, which can be installed close to the drill bit and directly in the drilling rig’s exploration pipe. It can be used in gyro tools or HDD tools.

**Near-drill-bit installation**

This is an aluminum alloy cylindrical MEMS north finder, 120mm long and only 30mm in diameter, light in weight and with good thermal conductivity. It can be directly installed near the drill bit or in the drill rig probe, and can independently measure the azimuth and attitude angles, more accurately control the well trajectory and reduce errors.

**High-precision north-seeking orientation**

The north-seeking accuracy of this north finder can reach 0.5°secψ(1σ), which can provide more accurate azimuth information. This is crucial for drilling operations that require precise orientation. At the same time, it is not affected by magnetic interference and can also be used in magnetic mining areas.

**Self-alignment and attitude tracking function**

After startup, it can automatically initialize alignment and then automatically determine the true north direction. No manual alignment is required, and the north-seeking time only takes 5 minutes. It can also track and provide attitude information to ensure that the drilling trajectory meets the design requirements.

**Adapt to harsh environment**

During the drilling process, there will be strong impact and vibration. It can resist high impact vibration and ensure stable operation. There is also a high temperature version with an operating temperature range of 5°C~+125°C. The low power consumption design of only 2W ensures stable output under continuous working conditions.

This north finder is designed to be more suitable for applications such as oil mining and drilling, especially in situations where precise control is required.
