Conclusion: The NF1000 delivers fast, precise north seeking and orientation, making it a valuable tool for directional drilling, military navigation, and other engineering applications. In military and civilian orientation, north finder is widely used. It can determine the north in static all-weather, all-round, fast and real-time, so as to determine the carrier azimuth, that is, the angle between a reference axis of the carrier and the true north direction, which is used as the azimuth reference for observation, target aiming and navigation system reset. It can also be used as a bearing reference for underground operations such as tunnels and mines in military applications, especially requiring the gyro north finder to achieve fast and accurate orientation in a short time. 1.Basic principles of north finding The north finder uses the gyroscope to calculate the angle between the carrier and the true north direction. This system uses a gyroscope and a quartz flexible accelerometer to form a strap-down system. The sensitive axis of an accelerometer is parallel to the sensitive axis of the gyroscope. The other is along the horizontal plane orthogonal gyro and accelerometer to form an inertial assembly relative to the installation base around the vertical axis according to the command of the control system rotation of the assembly around the vertical axis rotation two positions can be solved to measure the azimuth acceleration of the inertial assembly to compensate for the vertical component of the earth rotation angular velocity. 2.Oil drilling technology Oil drilling and development is a high-investment, high-risk, high-return, technology-intensive, capital-intensive industry, decision-making or operational mistakes will cause huge economic and social losses. With the improvement of the exploration level of oil and gas on land and sea, the types of oil and gas reservoirs have become complicated and diversified, the proportion of low and ultra-low permeability oil and gas reservoirs has increased year by year, and the well depth has developed from shallow and medium deep to deep and even ultra-deep. The types of oil and gas reservoirs are extended from conventional to unconventional. The sedimentary type expanded from continental to Marine. Exploration and development work has entered the stage of low, deep and difficult, which poses new challenges to oil and gas exploitation. In this case, the continuous use of vertical well technology will not meet the needs of modern drilling, so the directional drilling technology came into being. Directional drilling has always been considered “the process and science of deflecting a well in a specific direction in order to drill to a predetermined underground target.” As shown by the drilling directional north finder, azimuth angle and inclination angle are two key parameters for drilling hole positioning. The key performance indexes of gyroscope and accelerometer can be tested and calibrated automatically by using the built gyro north finder software. During drilling construction, the drilling rig arrives at the designated drilling site. According to the designed azimuth and inclination angle, the operator roughly predetermined the orientation and inclination Angle of the drilling rig, and then placed the north finding instrument at the horizontal place near the drilling site for north seeking operation; After the north finding is completed, the north seeker is placed on the guide rail of the rig to display the current rig attitude information (inclination angle and azimuth angle), and then the rig attitude is adjusted until the rig reaches the design angle. According to the problems we encountered in the drilling survey process, we launched a new shaped north finder NF1000, specially for petroleum mining, directional drilling and other engineering applications, it not only achieved a breakthrough in appearance, but also from the volume and weight have been greatly improved, its size is only mm Φ31.8 x85 mm, The weight is 400g, which has achieved a great breakthrough in the traditional inertial products of the North finder series. Its emergence allows more engineers to face more difficult, more limited space monitoring environment. 3.Summary Micro-Magic Inc north seeker uses a strap-down system. For the zero deviation drift and random error of the north finder, Micro-Magic Inc company has carried out many product technical reforms. At present, the latest north seeker NF1000 not only carries out inclination compensation and self-alignment functions, but also can be used in the probe. More limited monitoring space is facilitated.

Key Points Product: North Finder Inertial Navigation System Key Features: Components: Uses gyroscopes and accelerometers to provide precise inertial measurements for north-seeking functionality. Function: Quickly and accurately determines the north direction in all-weather conditions, independent of external signals. Applications: Suitable for both military and civilian uses requiring autonomous, interference-resistant orientation. Data Processing: Features advanced software for sensor data collection, processing, and attitude error correction. Modularity: Software is modular for ease of development, testing, and maintenance, allowing for flexible system upgrades. The appearance of north finder is an important achievement in the development of inertial navigation technology. It is widely used in military and civilian fields by configuring inertial sensors to form a precision inertial measurement system, which can accurately sense the relevant position parameters of the carrier, and provide various information resources such as coordinate position, orientation and attitude of the carrier with other equipment. North finder is an inertial instrument, it has the general advantages of inertial instruments, that is, the use of inertia working principle, does not rely on external information when working, does not radiate energy to the outside, will not be subjected to enemy interference in the work, will not be subjected to magnetic field substances and other environmental interference, good environmental resistance, in the high and low temperature environment performance superior, is an autonomous orientation indicating system. It can quickly and accurately determine the north in an all-weather environment. In the hardware of north finder, the sensor signal output of gyroscope and accelerometer is filtered, gated and amplified, and the analog signal is converted into digital signal by A/D converter to the control computer of the north seeking system for calculation and processing. The software of the north finder can be said to be the soul of the system, without the control of the software, the hardware in the system is virtually useless and can not play its performance. The software part controls the hardware of the whole system, sets the initial value, collects data regularly, human-computer interaction interface, and provides serial interface and network communication interface to realize the exchange of data with the outside world. The main content of the north finder software includes two parts: one is the management software, which makes the hardware work according to the predetermined program, such as the initialization of each part, the interrupt management in the running process, the communication management between the system and the external connection; The second is the data processing software, which samples the information of each sensor and processes the sampled data to prevent the output of the north finding result. Its main tasks are: 1. System initialization: including the initial position selection of the system, the feedback closing judgment of the gyro, A/D sampling initialization and so on. 2. System transfer control: the software controls the motor to rotate according to the predetermined position. 3. Data processing: A/D sampling and data preprocessing; Attitude matrix calculation and error correction; Display and output, etc. These tasks are intertwined in time and rely on interrupt management to coordinate them. In the design of north finder, we follow the basic principle of modularity, the program is divided into several modules, each module sets a function, and then these modules together to form a whole can complete the specified function. The advantages of developing modules with independent functions and without too much interaction between modules are mainly shown in: first, the software of modular implementation is relatively easy to develop. Second, independent modules are easy to test and maintain, and can be easily modified, replaced or inserted into new modules when needed. Micro-Magic Inc company in the north finder manufacturing has mastered the skilled technology, in the navigation system internal software and hardware, Micro-Magic Inc selection are cost-effective, high-performance inertial components, currently has a new type of north finder different from the traditional north seeker, is our NF2000, if you are interested in this, welcome to communicate with our professional staff.   NF2000 Inertial Navigation System High Precision Fog North Seeker
