Scud is a tactical ballistic missile produced and used by Lao Maozi in large quantities. It is also exported in large quantities. Although the relationship between Parthia and the Red Empire is not good, they have also obtained a batch through a third party, and they can also imitate it themselves.

However, the accuracy of Scud missiles is quite deceptive.

Although Lao Maozi claims that the maximum circumferential error is three hundred meters, that is to say, if you draw a circle with the theoretical impact point as the center and three hundred meters as the radius, the warhead should fall within this circle.

However, when it comes to actual use, whoever uses it will know.

The one who suffered the most misfortune was the opponent they had been fighting with for eight years. A few years later, they invaded neighboring countries and provoked the Western world. As a result, they were attacked by a joint attack by multinational forces.

They fought back, using Scud missiles, but the hit rate was too low, often within one or two kilometers. If the error could be within the 300 meters claimed by Lao Maozi, there would be many more tragedies like the Arab Dhahran Army Camp.

Maybe the Americans will have to get out of here in despair.

As for the Patriots' interception success rate, only God knows.

Now, the missile in front of us has an error of within a hundred meters, or even tens of meters, which is unthinkable. This is simply like using ballistic missiles for sniping!

"It cannot achieve long-distance attacks, but again, it is small in size, difficult to be discovered, and easy to hide. It is also very cheap and can be deployed in large quantities. On the battlefield, it can carry out attacks on important targets behind the enemy's positions.

Targeted killing." Qin Tao said: "I believe that this weapon will definitely meet your needs."

Qasim nodded repeatedly.

"So, starting from tomorrow, we will be able to display our weapon systems. Which one do you plan to see first?"

"Just this surface-to-surface missile." Qasim looked at the missile on the trailer. For some reason, it felt familiar.

The missile test was held in the morning of the next day. Early that morning, several vehicles set off from the base and headed north.

Of course, there is no possibility of cheating when testing missiles here. The launch location and target are all designated on site.

The road conditions here are not good. All the vehicles are all-wheel drive off-road vehicles. Qin Tao and the others are riding in a Bobcat armored reconnaissance vehicle imported from Germany. At this time, half of his body was exposed from the turret.

Looking at the surrounding mountains, I sighed with emotion: "The mountains and rivers here are as spectacular as those in our country!"

"That's right, our motherland will not be conquered." After hearing the translated words, Qasim agreed.

In the world, the few anti-American fighters who remain standing have their own reasons, and Parthia is no exception. It is either a mountain or a desert. The mission of the US special forces to rescue the hostages was due to the harsh nature here.

It collapsed under the circumstances and became one of the few shames.

Now, the convoy drove up a high mountain, and the Lut Desert in the back could be seen in the distance.

"Stop!" Qasim shouted.

The whole convoy stopped.

"This is our launch point." Qasim said: "In the desert over there, we find a predetermined impact point."

"Your Excellency Qasim, your question is a bit difficult!" Qin Tao said: "All these longitudes and latitudes are unknown, and there is also the factor of altitude. The wind is not light today."

Qasim smiled: "This is how we can test the true effectiveness of a missile in actual combat. If the error can be maintained within a hundred meters under this situation, then we will definitely purchase a large number of them!"

"Okay, but just planting a flag in the desert to designate the impact point is a bit too general. We need to send people to accurately determine the coordinates of the impact point so that the missile can hit it more accurately."

"certainly."

Kasim agreed. He couldn't point on the map: This is it! The error would be too big. In actual combat, the target of attack must be accurately located. Now, such harsh test conditions must also

Just precise positioning.

I just don’t know how they will use precise positioning?

Most of the vehicles stopped. Only one Lynx armored reconnaissance vehicle passed by with a Chinese personnel responsible for positioning. In his hand, he held a large brick-like instrument. I don't know what it was.

It's getting busy here too.

The M-7 missile trailer was quickly set up, the wheels were disassembled, and the chassis was securely fixed on the ground. Then, a support vehicle drove nearby, and several operators wearing gas masks appeared. They skillfully gave the missile

Add fuming nitric acid and kerosene provided by Parthia.

Qin Tao and others stood in the distance, watching this scene, pointing and introducing.

"The M-7 is a two-stage missile. The first stage is a solid rocket motor, which can be filled directly with propellant columns. The second stage is liquid fuel. Because we came by plane, in order to prevent accidents, we did not

Refueling, in fact, its fuel tank is corrosion-resistant and can store fuel for a period of time. Therefore, if it is a battle, you can refuel before setting off, drag it to the battlefield, prop it up and start fighting.

For hit-and-run, in addition to this trailer chassis, it also has a self-propelled chassis, which will make it faster."

Qasim nodded: "If we order them, they must all be self-propelled chassis. It would be better if its control equipment and missiles can be integrated into one vehicle, just like the Scud missile."

"Of course there is no problem, but the price of this method will be higher."

"Money is not an issue." Qasim waved his hand.

For countries with black gold at their feet, they don't care about money at all, especially for Parthia. It's not easy to buy weapons if you have money, so they don't care about the price.

A technician, holding a similar brick block in his hand, was operating in front of the missile.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "What positioning method did they use?" Kasim knew that they were positioning, but he felt strange about this method.

"Satellite positioning receiving terminal." Qin Tao introduced: "This is currently the most advanced positioning method."

If you want the missile to hit accurately, you must accurately measure both the launch location and the target location. After all, a slight mistake can make a huge difference.

Export-type weapon systems have already begun to use satellite positioning systems.

Specialized navigation satellites are launched into space. These satellites are equipped with the most precise atomic clocks, which continuously provide time signals. Terminals on the ground receive this signal and then compare it.

Compare to what?

Of course it's the time difference.

It takes a certain amount of time for this signal to reach the ground. The receiving terminal receives this signal, and then calculates the distance between itself and the satellite based on the stored satellite orbit information.

If the time signals of three satellites are received at the same time, there will be three distance values. According to the positions of the satellites and calculated using geometric knowledge, you can know your precise coordinates. If you add a fourth satellite, you can calculate it.

Highly informative.

In such an open mid-low latitude area, there are at least six or seven stars overhead, so the position can be determined very easily.

This method only passively receives signals and does not actively transmit signals. Therefore, when using this thing, you don’t have to worry about being discovered by others, let alone knowing your location.

The only risk is that someone cuts off the signal.

After all, the GPS system is used by the U.S. military. In 1983, a Kimchi country passenger plane deviated and flew towards Lao Maozi's intercontinental ballistic missile launch area, but was killed unceremoniously by Lao Maozi.

After the incident happened, the Americans announced that they would open their global satellite navigation system to civilian equipment.

However, the Americans still had a trick up their sleeves. They lowered the accuracy of the satellite positioning system. In fact, they blurred the precise time signal to prevent some users from using the system for military purposes without permission.

.

Before 1991, exported GPS terminals required a license. After 1991, there was no such restriction. As long as you have money, you can buy it.

A system that can accurately position will of course be used in the military. Moreover, the problem of insufficient accuracy was quickly solved by smart technicians. Since the Americans take the initiative to make errors, let's eliminate the errors!

The Americans soon discovered that a large number of differential positioning terminals came out.

According to different principles, there are three correction methods. Among them, pseudorange difference is the most widely used. This requires a special ground reference station where all satellites are observed. Based on the known coordinates of the base station and the coordinates of each satellite, the

The real distance of each satellite to the base station at each moment is calculated to calculate the real time signal value. Then it is compared with the satellite value to obtain the pseudo-range correction number, which is then transmitted to the user receiver. After a lot of trouble, you can

Get meter-level positioning accuracy.

In later generations, for the convenience of users, the motherland even established 20 beacon stations (that is, the base stations of the differential system) along the coast from south to north, sending RTCM differential correction information 24 hours a day without any interruption.

The user only needs the GPS of a mobile station to achieve high-precision real-time positioning.

The Americans stared, but there was nothing they could do. It was just like satellite TV. It cost a lot of money to launch communication satellites, but it was not free for users. However, after cracking the terminal password, countless satellite receivers were used by copycat manufacturers.

Produce it, buy it once and watch it for free for life.

After all, this satellite signal is broadcast, and there is no way to control who receives it. However, if you are in a hurry, you can cut off the satellite signal.

The Americans once did this, completely losing the positioning signal in a certain area.

Therefore, if you use other people's systems, you will be controlled by others. In order to avoid this situation, the country has vigorously developed its own satellite navigation system. The famous Beidou has also become the pride of the motherland.

(Beidou is a satellite. Most mobile phones in later generations have built-in Beidou receiving chips. Whether we use Baidu or Amap, we are already using various satellite signals, such as GPS, Lao Maozi’s glonass, and ours.

Beidou, never spend money to buy some Beidou navigation app, this is Li Gui.)

Now, with the use of high-end differential GPS navigation terminals, it is possible to locate the launch coordinates and target coordinates to the meter level. This kind of strike accuracy will of course be much higher.

A call came from the radio: "The target has been determined, location coordinates..."

A television camera and broadcast equipment were left there. After all, it was too dangerous for people to observe. The situation of the target was also transmitted from the TV screen here: in the endless desert, on a random sand dune, there was a

I picked up a flag and fluttered fiercely in the wind.

The car that arranged the impact point drove a full five kilometers away and established a special observation position. They were waiting for the next moment.

In the missile launch preparation vehicle, the atmosphere was a bit tense. Various data were input into the computer, ballistics were calculated, and the flight path was designed. Everything was going on in an orderly manner.

Three minutes later.

"Preparations have been completed, request for launch!"

When he heard this voice, Qasim was very excited: "So fast? We need to prepare for more than thirty minutes to launch the Scud missile!"

"Of course, we have the most advanced missile launch system." Qin Tao said.

The Scud missile is a liquid missile, and the fire control system is also very primitive. The ballistic calculation uses a mechanical computer, which can quickly go to hell.
