What is a gyroscope used for?

A gyroscope is a sensor used to measure angular velocity. Its core function is to sense the rotational motion and attitude changes of an object. It can be applied to various fields that require navigation, positioning or stable control.

ER-MG-057, as a high-performance single-axis MEMS gyroscope (angular velocity sensor), has become an ideal choice for many professional fields due to its excellent performance and reliable design.

ER-MG-057 - Born for precise navigation and stable control in harsh environments

**Precise measurement and stable output**

Wide range: ER-MG-057 has a wide range of measurement up to ±400°/s, which can meet the angular velocity monitoring needs of various dynamic scenes, covering high-speed rotation scenes (such as drone maneuvers and high-speed operation of robotic arms).

Excellent stability: tactical-level high precision, zero bias instability as low as 1°/hr, angle random walk (ARW) 0.2°/√hr, 0.1dps ultra-low noise, 200Hz bandwidth combined with 2kHz data output rate, real-time capture of instantaneous angular velocity changes, and response delay of only 2ms.

**High integration and high reliability**

Ceramic LCC surface mount package, with airtight packaging to protect the core MEMS structure, is only 11x11x2mm in size, easy to integrate into various systems, and RoHS certified.

Supports 5V (4.75~5.25V) power supply, power consumption is only 35mA, with low power consumption, default internal synchronization mode, optional external synchronization, compatible with multi-system architecture.

Can work stably in strong shock (12g RMS) and vibration (1000g 5ms 1/2 sine wave) environment, suitable for high vibration scenarios such as aviation drones and unmanned vehicles.

**Application scenarios**

Navigation and positioning: suitable for scenarios such as inertial navigation system (INS), drones and autonomous driving. Combined with accelerometers, position, speed and direction are calculated by measuring the angle change and acceleration of movement.

Precision instruments and stabilization systems: Ensure precise control and attitude stability of mechanical movement, and improve the real-time and accuracy of target tracking.

UAV/aircraft stabilization: Provides data for the flight control system to sense the attitude changes (pitch, roll, yaw) of the aircraft, so that it can adjust the motor speed to keep the aircraft hovering steadily or flying according to instructions.

Ship/vehicle stabilization system: Large ships use gyro stabilizers to reduce roll; provide reliable attitude data support for autonomous driving.

Robot balance and control: Help robots sense tilt angles and maintain their own balance and motion control.

HDD technology breakthrough! North seeker helps with orientation in trenchless construction

As the core technology of trenchless pipeline laying, HDD technology places extremely high demands on the direction control of the drill bit. The precise control of the drilling trajectory depends on high-performance directional measurement equipment. With its unique technical advantages, the ER-MNS-09 north seeker has become a key equipment for improving construction efficiency and accuracy in HDD operations.

Core challenges and directional requirements of HDD construction

HDD construction requires the completion of pilot hole drilling, hole expansion, and pipeline pullback processes underground. Directional equipment needs to meet the requirements of narrow space adaptation, high-precision orientation, resistance to complex environmental interference and impact vibration, and adaptation to extreme working conditions.

ER-MNS-09’s technical advantages and HDD compatibility

**High-precision measurement to ensure trajectory control**

The azimuth accuracy can reach 0.25°, and the attitude accuracy is ≤0.2°. With a data update rate of 100Hz, it supports stable operation in the inclination range of -85~85°. The operator can adjust the drill bit trajectory in time based on the measurement data to meet the strict restrictions on trajectory deviation in HDD construction;

**Ultimately compact design, embedded in the core space of the probe tube**

The HDD guided probe pipe needs to be embedded in the front end of the drill pipe, and the size and weight of the equipment are limited. The ER-MNS-09 north seeker has a diameter of only 30mm, a length of 120mm, and a weight of ≤150g. It can be seamlessly integrated into the probe pipe or guide head at the front of the drilling equipment, and is suitable for mainstream drilling equipment.

**Autonomous north finding and anti-magnetic interference**

Adopting a high-precision MEMS gyroscope that can self-find north, the initial alignment is completed in 5 minutes, completely free from dependence on the geomagnetic field, and can stably output the true north azimuth, pitch angle and roll angle information in strong interference environments such as underground mines, metal pipelines or strong electromagnetic environments.

All-solid-state design: no mechanical rotating parts, excellent anti-impact and vibration ability, meeting the reliability requirements under severe vibration conditions during drilling.

**Wide temperature adaptability to cope with extreme working conditions**

Full temperature calibration compensation: The normal temperature version supports an operating temperature of 5~+55°C, and the high temperature version supports 5~125°C. It can withstand strong vibration and shock environments to ensure long-term reliability in deep wells, mud environments or high shock conditions.
