Chapter 342: Immediate Retrofitting

"It's too ingenious," an old engineer muttered, "this kind of optimization approach is simply..."

Li Mingyuan had no time to listen to flattery and quickly assigned tasks: "Engineer Zhang, you are responsible for the signal processing algorithm; Engineer Li, you are responsible for data encryption and transmission; Engineer Wang, you are responsible for the core calculations of the triangular positioning; everyone else, assist with testing and optimization. Within three days, I want to see a functional prototype system!"

At the same time, the work of the second group was also proceeding in full swing.

Engineer Wang brought his team to the airfield, where three high-altitude reconnaissance planes were already parked on the runway.

These aircraft were imported from Beijixiong Guo and had undergone preliminary modifications, allowing them to fly at high altitudes for extended periods.

"Comrades," Engineer Wang said, pointing at the planes, "our mission is to install specialized radio transmitting equipment and antennas on these three planes. We must ensure the signal is strong enough, the coverage area is large enough, and the frequency is stable."

He took out the design drawings Li Mingyuan had just drafted: "Each plane must be equipped with three sets of transmitters of different frequencies, serving as backups for one another. The antennas must be modified into a directional adjustable type, capable of automatically adjusting direction based on the flight attitude to ensure the signal is always pointed toward the target area."

"Engineer Wang, with such complex modifications, are three days enough?" a mechanic asked worriedly.

Engineer Wang gritted his teeth: "Whether it's enough or not, it has to be! Chief Engineer Li said, we would rather go three days without sleep than fail to finish on time. Everyone, perk up and split up!"

The challenges faced by Lao Liu's third group were equally immense.

They needed to install a brand-new receiving and computing system onto the missile, capable of receiving signals sent by the three planes, calculating its own position, and then adjusting the flight path according to the target coordinates.

"This computing unit must be small enough, light enough, and also resistant to high temperature and high pressure," Lao Liu said, fretting over the disassembled missile warhead, "conventional electronic components simply won't work."

Just then, Li Mingyuan rushed over in a flurry, holding a small box in his hand: "Lao Liu, look at this!"

Inside the box was a circuit board the size of a palm, densely packed with various components, with a square metal casing in the center.

"This is a Small Computing Unit I designed specifically based on Third-Generation Computer technology. The volume has been reduced by 80%, but the computing power has only decreased by 30%, which is enough to handle the calculations for positioning and navigation."

Lao Liu took the circuit board with pleasant surprise and carefully inspected it: "Can a computer this small really work?"

"Of course it can," Li Mingyuan laughed, "and it's high-temperature resistant and shock-resistant; it has already passed preliminary tests. Now your task is to integrate it into the missile's control system so that it can receive and process the signal data for the three-point positioning."

Lao Liu excitedly patted Li Mingyuan on the shoulder: "Chief Engineer Li, you are always able to create miracles! We will start the modifications immediately."

The three groups split up to act, and the entire military factory suddenly became busy, brightly lit, with people coming and going.

Li Mingyuan worked almost without sleep or rest, rushing back and forth between the various groups to solve all kinds of technical problems.

During the day, he deduced algorithms and debugged equipment in the laboratory; at night, he supervised installations and tested systems in the workshop.

"Chief Engineer Li, you must rest," Lao Liu said, looking at Li Mingyuan's bloodshot eyes with concern, "your body won't be able to take it if you go on like this."

Li Mingyuan shook his head and gulped down a large cup of strong tea: "Rest for what? The enemy country's biochemical weapons could come at any time; every hour of delay adds a point of risk. Besides, having transmigrated to this era, isn't the point to change history? This is a once-in-a-lifetime opportunity!"

Late the next night, Li Mingyuan finally finished writing and testing the core algorithm.

After receiving the signals from the three planes, this algorithm could quickly calculate the real-time position of the missile and then automatically adjust the flight path according to the preset target coordinates.

"It's incredible," the engineer from the test group said, looking at the simulation results on the computer screen,

"The theoretical accuracy has reached 7.5 meters! This is already more accurate than the enemy country's most advanced Guidance System!"

Li Mingyuan smiled wearily: "We won't know the actual effect until the flight test. Between theory and practice, there are still many unknown factors."

At dawn on the third day, the three groups of people finished their respective tasks almost simultaneously.

Engineer Wang's team successfully modified the three high-altitude planes, each equipped with specialized radio transmitting equipment and adjustable antennas.

"The test was perfect," Engineer Wang reported to Li Mingyuan, "the signal coverage of the three planes exceeds 800 kilometers, enough to cover the entire target area. Moreover, the signal stability is extremely high; it can maintain stable transmission even in high-altitude turbulence."

Lao Liu's team also completed the modification of the missiles. They successfully integrated the Small Computing Unit designed by Li Mingyuan into the missile's control system and installed the specialized receiving antenna.

"The preliminary test was very successful," Lao Liu said excitedly, "the missile can accurately receive and parse the three-point positioning signals, the computing unit runs stably, and the control system responds quickly."

The achievements of the three teams were displayed together in the Main Workshop, and Minister Zhang and the Director of the Military Department came to inspect them in person.

"This is our 'High-Altitude Three-Plane Radio Positioning Guidance System'," Li Mingyuan introduced to the leaders, pointing to the equipment model on the table,

"The three high-altitude planes form a triangular array, continuously emitting coded signals. The missile receives these signals and, through time differences and signal strength, calculates its own real-time position, then automatically adjusts its flight path according to the preset target coordinates."

He picked up a small metal box: "This is the core of the system—the Small Computing Unit. It integrates our most advanced electronic technology and algorithms, capable of performing complex calculations during high-speed flight to ensure the missile hits the target precisely."

Minister Zhang and the Director of the Military Department carefully inspected all the equipment, their expressions gradually changing from skepticism to amazement.

"Chief Engineer Li," the Director of the Military Department finally asked, "how is the reliability of this system? Can it work stably in actual combat?"

Li Mingyuan answered candidly: "Theoretically, the system's positioning accuracy can reach within 10 meters, enough to ensure the missile precisely strikes the biochemical weapon facilities. But the actual effect still needs to be verified by live-fire testing."

"Then let's test it!" Minister Zhang decided decisively, "Conduct the live-fire test at the Northern Test Range tomorrow; three planes and two modified missiles, get everything ready!"

Just like that, in a short span of three days, Li Mingyuan and his team created an almost impossible miracle—developing an unprecedented high-precision long-range guidance system.

This system integrated multiple cutting-edge technologies such as radio positioning, real-time calculation, and automatic control.

When the three modified high-altitude planes and the two "Air Strike-1" missiles mounted with the new Small Computing Unit were transported to the Northern Test Range, Li Mingyuan stood at the workshop entrance, watching the departing convoy, his heart filled with mixed emotions.
