Chapter 798

Of course, starlight navigation is good, but it also has unavoidable shortcomings, the most important of which is natural weather.

It's good at night. The stars are shining. The method of using the stars to locate the city was used by the ancestors thousands of years ago, not to mention the modern people whose technology is advancing by leaps and bounds.

As a matter of fact, astronomical automatic compasses and light sextants, which rely on stars to calibrate their tracks, have been widely used in the navies of various countries since World War II.

After World War II, it was miniaturized and equipped with large bombers. For example, the B52 strategic bomber of a large foreign country was equipped with the most advanced MD-1 astronomical automatic compass and ks-85 light point sextant at that time to form a night navigation system, so as to enhance the combat capability of the B52 strategic bomber.

Yes, this kind of distributed star navigation system can only be used at night, and it can only be used in sunny weather, and it will be greatly reduced in daytime or rainy days.

This is also the reason why when radio navigation and satellite navigation are widely used, star navigation based on astronomical automatic compass and light sextant is rapidly reduced to backup navigation and is facing elimination.

Not to mention the poor accuracy, the limitations are still large, it is difficult to respond in time under the rapidly changing conditions.

Don't the two superpowers, the United States and the Soviet Union, know the limitations? Of course, they know, but they still choose to use the star navigation system on their long-range ballistic missiles, and cooperate with the inertial navigation system to form the final precision strike combination.

Why?

It's very simple, because the starlight navigation technology of the United States and the Soviet Union has already got rid of the natural limitations of the conventional astronomical automatic compass and light sextant, and really achieved all-weather, automation and high precision.

Otherwise, the missiles of the United States and the Soviet Union can only be used when the weather is fine at night, and the rest are windy and rainy, and they can only lie in their nests during the day. That's not true. Unfortunately, they were bombed by a missile of the other side that day. When they counterattack, they have to watch the sky at night, feel that there are dark clouds, and have to discuss with the other side. When the weather conditions permit, when they launch the counterattack?

If so, the confrontation between the United States and the Soviet Union for nearly half a century is not a cold war. It should be called a war of laughter. There is no such joke.

In fact, it is impossible for the United States and the Soviet Union to joke in such a critical field. The two countries have really reached the level of joining hands to lead the world and jointly crush the world.

As for how to do it, the principle is not complicated.

Stars in outer space not only transmit visible light, but also radiate cosmic electromagnetic waves such as X-rays and gamma rays. Then, according to astronomical theories such as spectra, we can determine the distance, mass and other basic information of stars in outer space.

This is the principle used in the star navigation systems of the United States and the Soviet Union. Therefore, the star navigation systems of the two countries are not simple optical devices, but radio telescopes close to the astronomical field.

In this way, the star navigation system of the United States and the Soviet Union can be used not only at night, but also during the day. Even if it is windy and rainy, lightning and thunder are still unaffected.

After all, the climate can affect the visible light, but the invisible star radiation can not be blocked.

As for interference, let alone the fact that all kinds of rays are mixed together, which is extremely complex. How much power equipment is needed to fully cover it.

Even if someone does come up with a device that can interfere with the radiation of extraterrestrial objects, do you know which extraterrestrial object is anchored by the starlight navigation system on the long-range missiles of the United States and the Soviet Union?

Because of this, the United States and the Soviet Union improved the starlight navigation system from visible light to invisible light, and its concealment is still surprisingly good. Then, combined with inertial navigation and navigation computers, the long-range missiles of the United States and the Soviet Union can crush all living beings in the world in quantity and quality.

Of course, this kind of rolling is only the history before 1991. Now, in 1994, this kind of history seems to be gone forever. At least now, the ty-6 UAV, which is flying in the sky outside eastern Zhejiang, has the capabilities of the United States and the Soviet Union.

You know, not long after the passage of Typhoon No. 11 this year, the weather conditions of the whole offshore area of eastern Zhejiang are not very good. The cloud layer is very thick, not to mention that some areas are also accompanied by rainfall.

If the ty-6 UAV only uses the visible star navigation system, in the daytime, when the weather conditions are extremely bad, it will be like looking for a dead end. Because there is no star position that can be anchored, what about navigation.

But now ty-6 drones are enjoying themselves in the open sea of eastern Zhejiang. What does it mean to regard the light interference in the daytime and the bad weather as nothing?

The zenith-1 star navigation system is the same technology as the similar navigation devices on the long-range missiles of the United States and the Soviet Union during the cold war.

In fact, the zenith-1 used by ty-6 UAV is comparable to the starlight navigation system of the United States and the Soviet Union during the cold war. The reason for this is very simple. The lineage of zenith-1 starlight navigation system is a mess.

The prototype of the system is the Soviet stellar-5 β star light inertial navigation compound guidance system.

It may be puzzling to say that this abrupt model, but the target of this system is a household name. It is the core guidance system of Baiyang intercontinental ballistic missile, the last intercontinental missile in the Soviet era.Relying on the stellar-5 β star light inertial navigation compound guidance system, the Soviet Union's "Baiyang" intercontinental ballistic missile has achieved an amazing range accuracy of 220m (circle probability) at 11000km.

A few years later, Russia ranked first in the country, and the Baiyang m, which was developed on the basis of Baiyang ICBM, did not exceed this accuracy. The reason is very simple. After the disintegration of Russia, it has no ability to develop a new generation of star light navigation system at all, and can only use the Star-5 β star light inertial navigation composite guidance system. Therefore, in addition to increasing the warhead and range, it has no real nuclear power There is no substantial breakthrough in the heart's Precision Strike ability.

It doesn't matter if there is no breakthrough. The stellar-5 β Stellar Inertial Navigation composite guidance system left over from the Soviet era is enough for Russia for many years. You know, this system is a high-precision navigation and guidance system that the Soviet Union spent a lot of money to develop against the United States.

In addition to the Baiyang intercontinental missile, its prototype star 5 a star light inertial navigation compound guidance system is used in the famous "okra" medium and short range ballistic missile of the Soviet Union. In addition, it has a range of 500 km and an accuracy of 150 meters.

In the 1980s, this precision was at the level of adverse weather. What's more, the Soviets only used a set of star light inertial navigation compound guidance system, which is enough to reflect the Soviet Union's strong strength in ballistic missile guidance.

Of course, few people may know about the "Oka" medium and short-range ballistic missile. After all, this missile was destroyed at the end of the 1980s, but another missile developed on its basis is famous. It is Russia's "Iskander" medium and short-range ballistic missile that has shocked the West.

The stellar-5-kk Stellar Inertial Navigation compound guidance system is an improved aircraft version based on the missile special equipment. The Soviet "mysterious" high altitude reconnaissance plane and Tu-160 strategic bomber, known as u-2sky, are equipped with this stellar-5-kk Stellar Inertial Navigation compound guidance system.

It's no exaggeration to say that the zenith-1 star navigation system of ty-6 UAV is well-known. If you don't perform well, you won't disgrace your brother and sister ~ ~
