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).
