Precise application of high-performance dynamic FOG north seeker in mining and oil exploration

 

The orientation accuracy of drilling equipment directly affects the efficiency and safety of logging drilling, tunnel excavation, and ore body positioning. During underground drilling operations, the vibration and attitude changes of the drilling rig are frequent, and traditional mechanical gyroscopes or magnetic compasses are difficult to work stably.

ER-FNS-01D high-performance dynamic FOG north seeker can achieve real-time accurate north seeking and attitude following in a vibrating environment. The north seeking accuracy can reach 0.5°, and the attitude measurement accuracy can reach 0.03° (1σ). Dynamic north-seeking technology can provide the true north direction of the carrier in real time. The working latitude of 65°N-65°S covers major mining areas and oil and gas fields around the world, ensuring that the drilling rig can still accurately control the drilling direction even when tilted or vibrating.

The compact size of 100×100×75mm and the lightweight design of 1kg make it easy to integrate into drilling equipment. Its core technical advantages are precisely targeted at complex working conditions:

Fast and precise dual modes: Supports 30-second fast alignment (azimuth accuracy 1°) and 90-second precise alignment (azimuth accuracy 0.5°), significantly shortening the equipment startup time. It can quickly establish the north reference after the drilling rig is in place. At the same time, its 20-minute accuracy retention capability allows the drilling rig to quickly resume operations after a short stop, reducing the time loss caused by repeated alignment.

Full environment adaptability: 5℃-55℃ full temperature range compensation technology adapts to the temperature difference between the deep mine and the field; there is humidity, dust and potential electromagnetic and metal interference in the mine, and the ER-FNS-01D is not affected by the magnetic field, which completely avoids the influence of the electromagnetic environment on the measurement results.

Strong vibration adaptability: The built-in shock absorber design can withstand 20Hz-2000Hz, 6.06g vibration environment, solving the problem of accuracy drift caused by vibration in dynamic operations of traditional north-seeking equipment.

✈️Flight safety secrets: The core role of high-precision IMUs in aviation

 

✨ High-precision IMU plays an irreplaceable role in the aviation field. It provides key data support for the flight control system (FCS) by providing the acceleration and angular velocity of the carrier, and combining algorithms to solve attitude, speed and position information.
✅ Take a high-precision IMU ER-MIMU-02Mini as an example for analysis.
✅ In the flight control system, the data provided by IMU is the basis for the autopilot to achieve precise control. The autopilot continuously adjusts the flight parameters of the aircraft based on the data of IMU to ensure the stability and safety of the flight process.
🔷 Excellent precision performance 🔷
👉 Gyroscope bias instability is 0.03deg/hr, and angle random walk is <0.01 °/√h; accelerometer bias repeatability is 100μg, and class II non-linearity coefficient is <100μg/g². 400Hz high-frequency data output, power consumption as low as 2W.
👉 Such high-precision measurement capabilities can accurately measure the attitude changes of aircraft in aerial photogrammetry. Using the information provided by IMU, the captured images can be accurately geometrically corrected and positioned.
👉 This makes the drawn maps more accurate and can meet the needs of high-precision geographic information in urban planning, land surveying, geological exploration and other fields.
👉 In the aircraft's navigation system, the high-precision IMU cooperates with other navigation equipment to form a navigation system. When the GPS signal is interfered with or fails, this IMU can switch to the main navigation data source in a short time to ensure that the aircraft's navigation system continues to provide accurate position and attitude information.
🔷 Compact and lightweight design 🔷
👉 Adopting modular design, the size is only 40*40*42 (mini version with shell)/27*26*34 (mini version without shell and baseboard), and the weight is 80g (mini version with shell)/ 40g (mini version without shell and baseboard).
👉 This compact and lightweight design is crucial for the aviation field, which is extremely sensitive to weight and space. It can effectively reduce the load of equipment such as drones and aircraft, and improve flight performance and efficiency.
🔷 Powerful integration and compatibility 🔷
👉 It can be customized by OEM, has good integration and compatibility, and can be easily integrated into various systems.
👉Simple operation can connect to the system and obtain IMU data. At the same time, by removing the baseboard shell, the size and weight of the IMU can be greatly reduced.
