Chapter 1369 Concentrate reconnaissance resources!
When the first ray of rising sun in the morning penetrates the night sky over China.
The North American continent located on the other end of the earth has just entered the darkness.
The three hundred meters underground of the Cheyenne Mountain always exudes the unique metal chill of precision instruments. General Lance Lord's fingertips gently tap the office desk in front of him, and the light blue light emitted from the display screen He was dizzy and jumped in his gray-blue pupils.
More than a dozen windows in front of me are playing satellite images in central China simultaneously, with red or yellow warning signs flashing on three of them—
That's the GPS signal breakpoint they deliberately created over the past three weeks.
"The ninth test results are still within the error range, indicating that the scheme that affects signal reception through artificial frequency jitter is quite successful."
Reconnaissance Director John Raymond will still take risks The hot report was pushed to the commander, and a dense stream of data appeared on the screen: "However, the international rescue team we sent found through actual testing that they received the double ends. Navigation equipment can switch to the Beidou port within one minute after GPS signal problems, and the impact on material transportation and engineering rescue operations is minimal. This is just a general-level information code. The equipment performance in the hands of the Chinese army will only be Better. ”
After a large-scale disaster occurs, countries will send international rescue units to provide assistance as usual.
But in addition to their jobs, they usually also undertake some low-sensitivity intelligence collection tasks, such as on-site inspections and loss assessments.
For this situation, everyone is basically in a tacit state.
After all, they are really helping, and it is impossible to let foreigners enter a particularly critical position anyway. It is not good to both sides if they really want to break up.
Of course, some countries are inevitably doing too outrageously, and they will still be hit by a certain degree of counterattack.
However, Americans are experienced in this area and usually handle it very accurately.
For example, this time, I am only responsible for field testing the functions of the Huaxia satellite network. Even if the other party knows that they are doing something, they can't say anything.
Admiral Lord nodded without comment, not particularly surprised by the result:
"What about navigation performance?"
After a while of silence, he Finally asked: "How much impact will it have on positioning accuracy and reaction time when the GPS signal is cut off?"
Raymond was prepared for this: "It's because we can't access the military code, so we can only speculate based on the civil code." Another report was raised: "The positioning accuracy of the navigation system was not greatly affected, but in the first 30 hours, the data update frequency was reduced by about 40% compared to before. Please note that Yes, it is possible that there are many factors that are superimposed, such as the damage to the ground station. "
"After this, China should have specially concentrated some of the communication relay navigation resources, according to the five Reports a hours ago showed that the response times of Beidou RDSS and RNSS services were shortened to 5.18 and 2.04 seconds respectively, both of which were about a quarter shorter than three days ago..."
"..."
After the report was completed, Raymond looked at the thoughtful old superior and asked tentatively: "Admiral, judging from the current results, GPS is restricted The effect of the signal is not obvious, and the other party should have noticed it long ago... If this information is leaked, it may be a big blow to our user trust. Are you considering returning to normal working state? "
A trace of hesitation flashed in Lance Lord's eyes.
The threat posed by the Beidou system in the commercial market is still very small, while Gronas can only maintain a complete rate of about 60%, and is almost unable to cover mid- and low-latitude areas. However, the Galileo system in recent years However, it has swept users on a large scale in the Middle East, which has had a significant impact on the pattern of satellite positioning systems.
Instead of answering the other party directly, he moved to a seemingly unrelated topic: "Last week, Sikorsky convinced Congress to allow them to release part of the UH60 helicopter exports. Restriction..."
Raymond didn't quite understand why the other party suddenly mentioned this matter, but continued to say:
"It's like this, probably because China has Equipped with a large number of Z12 and Mi17 series helicopters, it doesn't make any sense even if the UH60 parts supply continues to be restricted. It's better to take this opportunity to do a favor in exchange for part of the other party's general aviation market... You know, Miri, Kamov and Agusta has made a lot of money in China over the years, and it is difficult for Sikorsky not to be jealous."
"Well..."
Lord nodded, as if he had made up some determination. However, before he could make a decision, the orange alarm light sitting in the center dome suddenly began to flash.
Second Level Alarm.
This means there is some kind of emergency that deserves attention, but it does not have the possibility of evolution into actual conflict.
Lord looked up and saw a silver light spot representing the KH-12 keyhole satellite on the three-dimensional orbital diagram, passing through the roof of the world in southwestern China.
Immediately afterwards, the giant display switched out the optical imaging of the Hecheng Mountains of Hunan Province. It can be seen that in the valley covered by morning mist, a rather abrupt shadow appeared next to a seemingly ordinary mountain, and the ruts were nearby. The traces pressed on the road surface were also somewhat abnormal. "This is a photo taken by the keyhole satellite fifteen minutes ago." Colonel Devin Kenton, head of the intelligence analysis department, knocked his military boots on the floor in a rapid rhythm. He drew a radial analysis line on the electronic sand table: "In addition, infrared reconnaissance results show that the temperature of the missile assembly workshop of Base 55 rose by about 4.5℃ in the early morning of this local time... They said that their infrared camouflage work was done well, but they had to lower the protection measures during a brief window of time when vehicles entered and exited, and that they happened to be noticed by our new satellites that had orbital adjustments."
Low De took a deep breath and quickly realized the seriousness of the situation:
"What about the radar reconnaissance results of the lacrosse satellite?"
Col. Kenton shook his head helplessly:
" Pay attention to the vegetation around Base 55."
He As the answer was answered, the image was enlarged to decimeter resolution, and the dewdrops condensed on the camouflage web showed an unnatural refractive index in the morning light:
"A large part of the birch and elm trees were fake, The artificial electromagnetic structure formed by subwavelength metal resonance units on the surface of the leaves can decompose the incident radar wave into an abnormal polarization state. Our synthetic aperture radar has been weakened by 55% of its penetration, and the effect will not be more effective than optical and infrared reconnaissance. OK."
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
Raymond suddenly thought of something, and then called out the monitoring record three months ago: "At the beginning of this year, the construction progress of the insulation layer of the 55 base suddenly advanced, and even used it for this reason. Strategic reserve of quick-coagulation concrete."
He strode to the screen, pointing to the rut marks on the screen, and an analysis report on the relationship between trace depth and vehicle quality was displayed next to it:
"In addition, if these traces are left by a transport vehicle, the single-axle load will increase by more than 25% compared to the HY4330 used by Dongfeng 31, which is obviously unrealistic... Let's not talk about whether China can create it. Even if this level of transport vehicles can, such exaggerated pressure on the ground will make the passivity messy."
"In other words, this 814th Brigade should have been reinstalled in a large number of missiles, and may have 8-10 new missiles, and the transportation and transfer were completed during our satellite reconnaissance window."
General Lord's eyes swept across the strategic situation chart, and the coverage net of satellite constellations over the Asia-Pacific is slowly moving westward as the earth rotates.
He suddenly noticed the satellite transit timetable that the combat staff was adjusting:
"Let the NROL-14, NROL-18 and Ruby 07 satellites change their orbits, I will be in front of the next satellite communication window. Seeing the multi-spectrum scanning of the mountains in the northeast of Hecheng. "
Kenton's eyes showed a hint of hesitation, but he finally spoke:
"Your Excellency, if the locations of these two satellites are adjusted, then the tracking and monitoring of several blocks in central Mongolia and western Longyuan Province will have loopholes..."
He said halfway through his words..." It was interrupted by Lord's wave of his hand: "This force receives new equipment at such a high frequency, and it is very likely that it will be launched soon. There will be nothing like an intercontinental ballistic missile test. "But Colonel Kenton just mentioned that the radar spectrum scanning effect around the base is very poor, and the opponent's infrared camouflage is very good."
Raymond also had some concerns about this:
"In the end, it is very likely that only the visible light part can obtain sufficient results, but the optical equipment will leave enough reconnaissance windows for the other party at night and in harsh climates..."
But Lord had obviously made up his mind. Determination: "If there is vegetation, it's better, but their launch positions are always relatively empty. If we can analyze the traces of vehicle activities in the past and in the next period of time, we can infer the other party. The launch location planned to be used. "
"As for the situation in Mengzhou..."
He looked at the map of China on the screen:
"Concentrate the remaining reconnaissance resources of this mission over the missile range in Longyuan Province. No matter where the tactical missile test is launched, it will always hit here... Besides, they can't cover the Gobi Desert with that kind of thing... Trees for disguise! ”
