What is a gyroscope north finder and its applications
Gyro north finder refers to a directional technology equipment that relies on the all-weather, pure autonomy, and no support characteristics of the gyroscope, and integrates control and algorithms based on the photoelectric integration method as the core principle. Due to the ability of the gyroscope north finder host to communicate with
The combination of total station (theodolite), also known as gyro total station, gyrotheodolite, gyro compass, gyro orientator, is a special precision measuring instrument used to measure true north position angle. Gyro North Seeking
The instrument measures the true northern position angle, which is simple, fast, and accurate, not limited by weather and time, and has no accumulated error. It has been widely used in multiple fields of military and civilian construction, especially in high levels, high requirements, and high difficulty
Provide precise technical support for surveying and mapping work.
The Principle of Gyro North Seeker
Gyro North Finder is a high-precision dual axis dynamically tuned gyroscope that measures the Earth's rotational speed and independently determines the true north direction value of the attached carrier, without being affected or interfered by external magnetic fields or other environments. In addition, it can also be combined with acceleration for horizontal angle measurement and correction.
What are the methods of using a gyroscope north finder?
Firstly, the accuracy of gyroscopes is higher than that of the Earth's rotation. There are two methods. One method is coarse alignment of inertial navigation, which can be understood as measuring the components of the Earth's rotational velocity on each axis of the inertial group under stationary conditions, and combining it with the attitude of the inertial group measured by the accelerometer to calculate the direction of Earth's rotation, namely the north. The second method uses the "representation motion" of gyroscopes The so-called characterization of motion assumes that there is a high-speed rotating gyroscope on the ground, and it is not affected by any interference. Therefore, the direction of its rotation axis is stationary relative to the inertial space due to its fixed axis, but due to the rotation of the Earth, the gyroscope axis can be observed to be drawing a circle relative to the ground. The center of this circle points north. Therefore, damping is added to the gyroscope to make it quickly converge, and the direction of the gyroscope axis obtained points north Mechanical gyroscopes can also be achieved through digital circuits.
Introduction to Dynamic Gyro North Seeker
The dynamic gyroscope north finder is a gyroscope that uses the strapdown compass effect to solve the true north direction. The dynamic gyroscope north finder consists of a three-axis dynamically tuned gyroscope, a three-axis plus meter, a data acquisition and processing module, a secondary power supply, an optocoupler isolated input/output serial port circuit, and other related structural components. After powering on and starting up, the product enters the preheating time, and after the preheating time ends, the product enters the initial self alignment under the condition of moving base. [1] After the product is powered on for 30 minutes, the aircraft carrying the product can sail at sea. During navigation, the product will output the heading angle, roll angle, and pitch angle in a timely manner. If applied on land and in the air, products can also be customized.
The dynamic gyroscope north finder is mainly used in the navigation industry. During navigation, the dynamic gyroscope north finder will timely output the heading angle, roll angle, and pitch angle.
The performance indicators of the dynamic gyroscope north finder include measurement accuracy, measurement range, preparation time, external input signal and error, etc.
