In the past ten years, laser gyros have replaced the position of mechanical gyro and occupied the high precision market. Compared with traditional mechanical gyros, advanced laser gyros are more compact and lighter, and are now widely used in military aircraft, civil aviation aircraft, ships and other equipment.

The development of modern science and technology has made industrial categories more and more diverse.

The original mechanical, electronic, chemical, aviation, aerospace, and weapons are no longer of much significance. Modern weapons are mostly complex mechatronic products. It takes mechanical, electronic, chemical, pneumatic, materials and other professional disciplines to be successful in order to succeed. Among the various weapons of complex sea, land, and air, there is a basic equipment that has long been the core equipment of the military power of military powers. This is Gyro.

Because modern weapons pay attention to long-range speed and high overload, high-precision measuring equipment is needed, so the whole world is working on gyroscopes, and various models have been developed.

Few people know that high-precision gyroscopes are missing. The submarine can't go to the sea, the bomber can't go out to sea, and the fighter can only wander around the coastline for dozens of kilometers. In recent years, the Chinese navy and air force have greatly advanced into the ocean, and the role of the advanced gyroscope has been outstanding.

Some people may say that there is no satellite navigation device such as GPS Beidou now? Why develop complex and expensive gyroscopes?

The reason is that although satellite navigation is convenient, the receiver is cheap, and the world is convenient to use, satellite navigation also has many weaknesses. The biggest weakness is that the satellite is at a high altitude of thousands of kilometers, the signal is very weak, easily interfered, and navigation. Satellites are also vulnerable to enemy attacks during wartime and have low viability.

The biggest advantage of the gyroscope is that the anti-interference ability is unlimited. So far, there is no way to interfere with the work of the gyroscope over long distances, and the gyroscope can also be used in underground, underwater, and enclosed spaces without any problem. It is something that no satellite navigator can do, and it is also one of the focuses of the world's major powers.

Traditional gyroscopes use mechanical rotor rotation mode to maintain positioning, which is a direct continuation of the inventions of China for thousands of years. However, this mechanical gyroscope has huge deficiencies, which are heavy weight, complicated processing, expensive price, large drift, and poor precision.

To achieve high precision requires a particularly large volume and weight, so scientists soon thought of another way, this is the laser gyro.

In the past ten years, the laser gyro has replaced the mechanical gyro position and occupied the high-precision market. The advanced laser gyro drift is less than 0.01¡ã/hour, and the average fault interval is more than 60,000 hours. It is better than the mechanical gyro. The advantage of the ring laser gyro is that There are no moving parts, so there is no friction, and there is no inherent drift. Compared with the traditional mechanical gyro, it is more compact and lighter. The laser gyro is now widely used in military aircraft, civil aviation aircraft, ships, space vehicles and other equipment.

Since the 1960s, China began to develop laser gyros, which began to catch up in the 1970s. Finally, in 1994, the product was finalized. In 1998, it was used on the Dongfeng series of ballistic missiles. The most dazzling thing is that the academician Gao Bolong spanned two generations. 0 Start chasing, skip the internationally mature two-frequency mechanical jitter laser gyro, and directly develop a new generation of quad-band differential laser gyro. The new generation of gyros has higher precision and uses a larger dynamic range to meet the needs of China's various advanced weapons. Use, including flying leopard fighters, ¼ß-10 fighters, etc.

After more than 50 years of hard work, China has made significant progress in laser gyro technology, and has made significant progress in fiber optic gyroscopes and MEMS gyroscopes, and began to use on various short-range precision guided weapons.
