Chapter 57 The Rover

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

"Sir, you can directly start the keyless..."

"Broken copper and rotten iron" gave Chi Heng instructions throughout the whole process. There was a start button under the rectangular steering wheel. After Chi Heng pressed the button, he felt the driver's seat vibrate slightly, and then fell into a calm state. This electric motor-driven vehicle , silent, and gasoline-powered vehicles are two completely different driving experiences.

It really started, and Chi Heng was both excited and nervous. Driving this big guy, the field of vision is far wider than that of a pickup truck, especially the 360-degree real-time video of the car on the screen in front of him, which is very amazing. The small screen of the rover is used as a rearview mirror to present a mirror image without blind spots behind the rover, which is completely unlike driving his broken pickup truck with blind spots everywhere.

Although this rover is very heavy and large, but after actually driving it, Chi Heng realized that due to the strong power of the motor and engine, there is no feeling that it is clumsy and unable to use force. In addition, it makes him mistakenly think The rover was even lighter than his pickup truck.

"Wait a moment!"

After driving excitedly for a while, Chi Heng realized, "Junk, since this car is found 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 of the car."

"Okay, Sir...the map has been invoked."

A three-dimensional electronic map suddenly appeared on the screen in front of him, showing mountains and terrains with a scale of hundreds of kilometers. On the entire three-dimensional map, a red dot and a blue dot appeared. Junk helped him zoom in on the map. It can be seen that the blue dot represents the rover, and the red dot represents an important location, separated by 217 kilometers.

"There are still 217 kilometers..."

Chi Heng has a bit of a headache. With such a long distance, it will take 5 hours to reach the destination from the "Moros Gate" by ATV alone. The round trip is equivalent to 10 hours. This is the premise that everything goes well. , if it encounters sudden extreme weather, it will be completely finished.

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

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

How did the old man solve this problem in the first place?
"Junk, what's the top speed of this rover?"

"Sir, the LK-3003 rover has a top speed of 120 kilometers per hour."

"A speed of 120 kilometers per hour..."

Chi Heng's heart moved, "However, it is impossible to maintain a speed of 120 kilometers per hour. On this road condition, an average speed of 90 kilometers per hour is not bad. Such a journey of more than 320 kilometers takes 3.5 hours, and the round trip takes 7 hours. I can still 5 hours of work left."

"Five hours of work is still a small amount, but it doesn't hurt to not compare."

After a few sighs, Chi Heng was ready to try it immediately.

He drove the rover out of the group of stone balls, bypassed it and entered the vast plain, quickly increased the power, kept increasing the speed, and soon reached a speed of 80 kilometers per hour. At this speed, the ATV has already rolled over However, the rover is very stable, and its shock absorption ability is so good that Chi Heng was surprised.

Then the speed increased to 90 or 100 kilometers. To be on the safe side, he maintained a speed of 100 kilometers per hour, and there was nothing wrong with it. In this way, he only needed a little over 3 hours to complete the 320 kilometers of road.

Returning to the area just now, Chi Heng stopped the car, thinking about how to mount the ATV, but finally told the "broken copper and iron", the robot pointed out that there is a lifting platform in the rear compartment of the rover to store supplies .

Chi Heng got out of the car and took a look. Sure enough, after pressing the button, there is an electric lifting platform behind the rover, which is used to facilitate the delivery of supplies into the cargo compartment. Storing an ATV is a breeze.

"Go back and tidy up."

Although there is not much dust in the rover, after all, someone died inside, Chi Heng was still a little bit shocked, and planned to clean the inside after returning home, and tidy it up by the way.

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

Looking at the time, Chi Heng was eager to try. With the speed of the rover, he could arrive at the destination in two hours, that is, before 12 noon.

but……

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

His GPS doesn't work in Absolute Territory, there's no GPS signal at all.

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

"Broken copper and iron" said: "The map in the rover is a high-precision three-dimensional map. Through the real-time collection and comparison of inertial navigation and AI images, you can roughly verify the location..."

"If this is the case, doesn't it mean that the steel coordinates can be used?"

Chi Heng was overjoyed, and then shook his head: "No, I'm afraid it won't work in extreme weather, and I can't see anything around. Junk, if we only use inertial navigation, can it be so accurate that we won't get lost?"

"Sir, I'm afraid this is not possible. The inertial navigation chip of the rover does not use the most precise atomic clock carrier platform. After the information of the ordinary navigation chip is generated by integral calculation, the positioning error will increase with the increase of time. The long-term accuracy reaches If there is no demand, it must be combined with AI images and images for real-time collection and comparison.”

"How long is the long term?"

"The inertial navigation accuracy of the rover is 1° per hour."

"0.01°?"

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

"Sir, the error will reach 144.05 meters."

"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 set the steel coordinates, when we return in the afternoon, record the inertial navigation data and locate Get to the door, so you don’t have to worry about getting lost in the future.”

"By the way, you just said that the rover does not use the most sophisticated atomic clock carrier platform... If it is used, how accurate can the inertial navigation be?"

Chi Heng asked curiously.

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

"1 centimeters?"

Chi Heng was extremely shocked. Doesn't this mean that even with a distance of 3200 kilometers, within 10 hours, the error will not exceed 14.4 meters?This is too strong.

"Huh, let's not talk about this, let's go to the destination to have a look."

Chi Heng is gearing up and can't wait to see what the research base of the red dot target looks like.
