Chapter 57 Roaming Car

Chi Heng has never seen a circular steering wheel, and this is the first time he has seen this rectangular steering wheel.

“Sir, you can start directly with keyless…”

"Broken copper and iron" gave Chi Heng the whole process. There was a start button at the bottom of the rectangular steering wheel. After Chi Heng pressed the button, he felt the driver's seat vibrate slightly, and then fell into calmness. This kind of electric motor-driven vehicle is silent and has completely different driving experiences from gasoline-driven vehicles.

When it really started, Chi Heng was both excited and nervous. When driving this big guy, his vision was far wider than that of the pickup truck. Especially on the screen in front of him, there was also a real-time image of the car at 360 degrees, which was very magical. The small screens on both sides used as rearview mirrors to present a blind spot-free mirror at the rear of the rover, which was completely different from the broken pickup truck that was driving him.

Although this rover was heavy and very heavy, Chi Heng realized that because the motor engine was very powerful and there was no clumsy feeling that it could not be used to force. In addition, when it was controlled, he mistakenly thought that this rover was lighter than his pickup truck.

"Wait a moment!"

After driving excitedly for a while, Chi Heng reacted, "Junk, since you found this car here, doesn't it mean that the research base is nearby?"

This possibility is very high!

Chi Heng's eyes lit up: "Junk, help me see if there is a map of the research base in the computer."

"Okay, Sir... has called out the map."

"Broken copper and iron" said: "The map inside the roaming car is a high-precision three-dimensional map. By comparing inertial navigation with real-time acquisition of AI images, the position can be roughly verified..."

"Sir, the error will reach 144.05 meters."

“How long does it take?”

Although there was no dust in the roaming car, after all, someone died inside, Chi Heng felt a little uncomfortable. He planned to clean the inside carefully after going back and sort it out.

Chi Heng looked at the three-dimensional electronic map on the screen in confusion and asked: "Junk, how is the navigation of this electronic map designed? Is there a satellite navigation signal here?"

"The inertial navigation accuracy of the rover car has an error of 0.01° every 1 hour."

Chi Heng had a headache. With such a long distance, it took 5 hours to get there from the "Gate of Moros" to get there, and it took 10 hours to get back to the destination. This is the premise that everything goes well. If you encounter a sudden extreme weather, you will be completely finished.

Chi Heng was happy and shook his head: "No, it may not work in extreme weather. You can't see anything around you clearly. Junk, if you only use inertial navigation, can you be accurate so that you won't get lost?"

Chi Heng felt aroused, "But it is impossible to maintain a speed of 120 kilometers per hour throughout the journey. With this kind of road condition, it would be good to have an average speed of 90 kilometers per hour. This way, a journey of more than 320 kilometers will take 3.5 hours, and a round trip will cost 7 hours, and I can still have 5 hours of working time."

Even if you save time without resting and just eat dry food, it is far from enough.

His GPS cannot be used in the "Escaping Realm", there is no GPS signal here.

“0.01°?”

"Although the five-hour working hours are still very small, there is no harm without comparison."

In addition, a 10-hour journey also means that he only has 2 hours of working time left. Is this time enough?

"If this is the case, wouldn't it mean that the steel brazing coordinates are not used?"

After looking at the time, Chi Heng was eager to try it. At the speed of the rover, he could reach the destination in two hours, that is, he could arrive before 12 noon.

but……

"The maximum speed of the Sir, LK-3003 rover is 120 km/h."

Chi Heng thought for a while: "Junk, substitute the formula, the distance of 320 kilometers, the time of 3 hours, what is the error?"

“There are 217 kilometers left…”

"Sir, using the latest atomic clock carrier platform, can improve the accuracy by 100 times on the existing basis, with a distance of 320 kilometers and an error will not exceed 1 cm within 3 hours."

After sighing a few times, Chi Heng was about to give it a try now.

A three-dimensional electronic map suddenly appeared on the screen in front of him, presenting mountains and terrain with a scale of hundreds of kilometers. On the entire three-dimensional map, a red dot and a blue dot appeared. Junk helped him enlarge the map specifically. You can see that the blue dot represents a rover and the red dot represents an important position, 217 kilometers apart.

Chi Heng asked curiously.

"It's still early, 9:27..."

He drove the rover out of the group of stone balls, bypassed the vast plain, quickly increased the power, and kept increasing the speed of the car, and soon reached a speed of 80 kilometers per hour. At this speed, the ATV had a great risk of overturning, but the rover was very stable and had excellent shock absorption ability to Chi Heng's surprise.

Returning back to the area just now, Chi Heng stopped the car and thought about how to mount the ATV. He ended up telling him the idea to "bad iron". The robot pointed out that there is a lifting platform in the rear compartment of the rover to store supplies.

The speed then rose to 90,100 kilometers. To be safe, he maintained at a speed of 100 kilometers per hour, and there was no big problem. In this way, he could drive the 320 kilometers of road in just over three hours.

"Sir, the navigation of the rover should use inertial navigation and AI comparison recognition here."

“A speed of 120 kilometers per hour…”

"You have to clean up when you go back."

"Sir, this may not work. The inertial navigation chip of the rover does not use the most precise atomic clock carrier platform. After the information of its ordinary navigation chip is generated by integral calculation, the positioning error will increase with the increase of time. The long-term accuracy does not meet the requirements. It must be compared in real-time acquisition and comparison with AI image images."

Chi Heng got off the car and took a look. Sure enough, after pressing the button, there was an electric lifting platform behind the rover to facilitate the delivery of supplies into the cargo hold. It was a trivial matter to store an ATV.

"By the way, you just said that the rover is not using the most precise atomic clock carrier platform... Then, if it is used, how much accuracy can the inertial navigation be achieved?"

"144.05 meters?" Chi Heng breathed a sigh of relief. He thought there was a big error: "This error is completely acceptable. Now there is no need to use steel drill coordinates. When you return in the afternoon, record the inertial navigation data and locate it at the door of your house, so that you don't have to worry about getting lost in the future."

How did my uncle solve this problem?

"Junk, what is the maximum speed of this rover?"

“1 cm?”

Chi Heng was extremely shocked. Doesn’t this mean that even if it is a distance of 3,200 kilometers, the error will not exceed 14.4 meters within 10 hours? This is too strong.

"Huh, let's not talk about this anymore. Let's go to the destination first."

Chi Heng was ready to go, and couldn't wait to see what the research base of the Red Dot Target looked like.
