Reaching for the stars with one hand

Chapter 19
At the same time when Zhang Yong was preparing to learn from Brother Xiao Ma and wanted to get back the contract belonging to Tiangong, Master Zhao also arrived in Huaizhou.However, Mr. Zhao didn't pay much attention to the engineering university contract that had almost been obtained. He didn't attend the Q&A meeting on the last day.

"It was too late for us to intervene. Don't talk about big-name competition like SKydon, even if it is a random brand, we have no chance to intervene. Others have done what should be done, and we are not on the list of consideration."

Master Zhao directly interrupted Akun's sigh, "Is there a possibility that someone can change the status quo and let us re-enter the game. It doesn't matter who this person is, as long as there is such a person. Don't worry about it even if you enter I can't compete with SKydon in the round, no matter what, I can't even be defeated without a chance to compete."

"Actually, as long as the chief dean says something, we can definitely enter the game. I tried, but it didn't work, and just like you thought, I was afraid that if we entered the game, we wouldn't have much chance, so I didn't demand it too strongly."

"What's the dean's attitude?"

"The dean is new here. He didn't participate in the preliminary research, and he doesn't want to participate. At the meeting the day after tomorrow, he is the one who decides, but he basically won't express his position. As long as the report is reported, he will accept it. And the people below ranked SKydon first, and we were not selected."

Master Zhao nodded, "You don't need such a good card? He doesn't care about it, which means he has no preference for any family. He doesn't want to care about it, which means he can care about it. You help me to ask him out."

"If you can't make an appointment, if you want to find someone else, you can still go to their courtyard to find the dean, and the guard will directly block you."

"Then don't make an appointment, you will go directly with me tomorrow."

Akun became interested, "Why, Mr. Zhao, I figured out a way."

"No," Mr. Zhao shook his head. "Let's adapt. I just think that if it takes a day, we can get 5 minutes of communication time. After these 5 minutes, we will decide whether to give up." This is Mr. Zhao's idea. way, it doesn't look very clever, but it has been very effective.If it was Xiaowei and it took him a whole day, he might even give up on the base station project.

……

The Q&A meeting of the University of Technology has begun. Everyone knows that the Q&A is just a formality. The conclusion meeting has been settled before the meeting. Although the people who support SKydon are very unwilling, they are very happy to face the result of 6:0 crushing in the forest. It will soon be defeated.

It was Master Zhao's assistant Li Hui who made the test summary for Tianshi.

After the polite opening, Li Hui summed up his test in a low-key but confident way, "Leaders, I don't really have much to say. After all, the comparison test is the result, and the result has already been placed in front of the experts. I I would like to say a little bit more. I am very grateful to the experts from the University of Technology for arranging this fair and just presentation. We all know that Jiawa is a small brand that is not well-known enough, so our performance is often ignored by people, and not many people really pay attention to us. , so we will also ignore the great progress of Jiawa in recent years. We have been working hard to improve ourselves. Especially for some pain points of users, such as the ability to work in difficult environments encountered in this test, I am also very proud. Let everyone see our efforts. Of course, compared to many big brands," Li Hui said, glanced at Tiangong, "we still have a lot of shortcomings, and we will continue to learn from our peers, thank you again Everyone, look forward to this final fair and just result."

Li Hui's speech was short but decent, and several experts nodded, thinking that they could give Tianshi another point.

"Please, Zhang, the engineer of Tiangong Group,... I'm sorry, how do you pronounce this word?"

Zhang Yong raised his hand, "It's me." Then he strode forward.

"Thank you, my name is Zhang Yong."

"Leaders, experts, hello everyone, thank you for inviting us to participate in the test, and thank you experts for being fair and impartial. Today is the last question-and-answer meeting, so let me talk more about technology-related things, let us The last bit of doubt in my heart has been resolved."

"Our test is divided into two days, and the accuracy comparison test is placed on the first day, so we continued to use the conclusion of the first day in the second day's test, that is to say, the accuracy of each company is no problem , or to put it another way, after the first day of testing, we have defaulted that as long as RTK can obtain a fixed solution, its accuracy is no problem. Experts, do I understand this right?"

An expert replied bluntly: "I don't know what the meaning of your words is? Is there a problem with this understanding? You should also be a GPS expert, so don't we need to explain the principle of the whole week ambiguity?"

The attitude of the others was similar to that of the expert who spoke. Everyone felt that Zhang Yong was just using words to quibble, and that his loss was not open enough.However, Ma Xiaoqing noticed that there was an imperceptible tension on Li Hui's face.

Zhang Yong was not in a hurry, "Thank you for your answer, we all know the principle, so there is no rush to talk about this, let me show you things first."

The expert spoke again, "This engineer from Tiangong, our Q&A this time is aimed at this test. If it has nothing to do with it, even if your documents can show that SKydon's equipment is extremely good, you don't need to show it."

"Okay. But what I'm talking about is the test results. Yesterday, we found a surveying and mapping team and used a total station to re-measure the six test points in the woods. The measurement results, as well as Tiangong, and I have drawn the measurement results of Tianshi on this map. I printed out the map. Brother Ma..."

Ma Xiaoqing immediately stepped forward, and gave each of the experts present a copy of the printed dot map.When he walked back to his seat, he deliberately passed by Li Hui, "President Li, would you like to accept a copy of this form?"

Li Hui's face was livid, and he snatched the picture from Ma Xiaoqing's hand.Ma Xiaoqing giggled and returned to her seat.

Laymen watch the doorway, and experts watch the fun. As soon as this picture was posted, it immediately attracted whispers from the expert seats.

"Experts, is it a little surprising that the accuracy of both sides is not good. Although one is a fixed solution and the other is still a floating-point solution, in comparison, the accuracy of the floating-point solution is even better."

Li Hui lost the demeanor of his speech on stage just now, and he hurriedly interjected, "How can you prove the authenticity of your picture and the point accuracy of your total station surveying and mapping?"

Zhang Yong nodded and said: "President Li is indeed an expert, this question is very relevant..."

"The measurement results of the total station come from a third-party company with surveying and mapping qualifications in this city. There is no doubt about their strength and qualifications. At the same time, this is not a surveying and mapping mission. We did not use any known points. I just customized them on site. I got the coordinate system, and then converted the GPS points to the same coordinate system for comparison. On the second page, there is the definition of my coordinates and the process of coordinate conversion, you can check.”

"If you still have objections to the results of this chart, I suggest that experts from the University of Technology arrange their own wire mapping. I just urge all experts and leaders not to rush if there are objections to the test results and they have not been verified. Draw conclusions."

Li Hui stood up, "Didn't you say that we cheated in the test? Everyone saw the results of the day. If we can restrain you, you can't. No matter how much you argue, it's useless."

Zhang Yong shrugged, but did not answer.The expert who spoke just now stopped Li Hui this time, "President Li, it's time for Tiangong to speak, please sit down first. If you have questions, you can arrange time to discuss them later."

After speaking, he turned to Zhang Yong, and his tone softened a lot, "Here is the chart, whether it is true or not, we will verify it after the meeting, we will definitely be fair and just, please rest assured that both of you companies. It's just that the result of the chart is just Explained the result, but couldn't explain the reason, this Tiangong expert, your name is Zhang Yong, right, Zhang Gong, can you explain it."

Zhang Yong's tense heart was half relaxed. He seemed to be talking eloquently, but in fact he was still extremely nervous.

"You are welcome, just call me Xiao Zhang, or just call me by my name. I also have a paper here, which talks about the confidence analysis of RTK fixed. Because the paper is very long and the time is short, I just simplified the middle paragraphs. Translate, Brother Ma..."

Ma Xiaoqing distributed a stack of printed papers to the judges again, and then couldn't restrain the joy in his heart, and said to Li Hui again: "Mr. Li, you also have a copy of this." answer.

"Some users once thought our equipment was too expensive, and suggested that the accuracy can be reduced, such as 10-15cm accuracy, and then the price will be lowered." Zhang Yong became more calm and told the story.

Our answer is, "No, no doesn't mean that it can't be done, but that there is no such equipment at all. From the perspective of RTK's fixed state, there is a saying in the West that is either right or wrong, either right or wrong, here There is no in-between state."

"In this paper, there is a difference and comparison of RTK initialization reliability of 99.99%, 99.9% and 95%. In fact, Mr. Li just said seriously. Tianshi is both a competitor and a friend. We never think that Mr. Li's side It's cheating, it's just that some manufacturers have quietly lowered some standards on certain designs."

"Well," the expert looked at the paper in his hand, listened to Zhang Yong's explanation, and suddenly asked again, "This method is very advantageous in this kind of comparison, doesn't Skydon have such a setting? "

"Because the ultimate meaning of surveying and mapping equipment is surveying and mapping, not competition. If our surveying and mapping colleagues regard low-precision coordinates as qualified controls during surveying and mapping, it may have serious consequences. We would rather lose the order than do such a thing. SKydon is always 99.99% on RTK reliability indicators, you can look at our coloring page again.”

These few words were spoken sonorously and forcefully, and the spirits of several people were shocked when they heard them, and Li Hui's face became more and more ugly.

Some people also looked through the product information of several companies and found that SKydon did write 99.99%, but it was the only manufacturer with this indicator, and no other manufacturer had this indicator.

Seeing Li Hui's appearance, the expert laughed and smoothed things over, "It's not that serious. We are mainly teaching. Generally speaking, there won't be such serious consequences."

The experts put their heads together and studied in a low voice for a few minutes, and then the expert team leader announced, "Because there is a new situation today, and the results of the data provided by Tiangong still need to be verified, so today's meeting will be At this point, the two sides should not leave Huaizhou for the time being, we will make further verification and discussions before giving a final conclusion, thank you for your participation."
