Yang Shouzhuo couldn't help but laugh out loud: "Oh, your wooden head finally started to move."
Li Wenjun sighed: "I'm using our latest smartphone. The one with GPS positioning and navigation. Otherwise, how would I have known that we were fifty kilometers away from Tohoyandu? How would I have known that we were not going wrong? I've been watching the navigation. It’s just that you were just walking forward and didn’t notice that I was looking at the navigation.”
Tao Guangming said: "You are coaxing me again. Just now there was no mobile phone signal for GPS positioning and navigation."
Li Wenjun: "That's a good question. I usually ask you to pay more attention to the professional trends of various factories, but you don't care. Because the GPS mobile phone signal does not use a line. GPS receives satellite signals through the GPS module in the mobile phone. The mobile phone signal is received The signal of the base station signal tower. So even if there is no phone card and navigation software, it can still be positioned normally. I tried two aspects of the mobile phone at once, one is the navigation software and the other is the GPS module."
Since the last time I told Yang Shouzhuo and others that mobile phones and cars should use satellite positioning and navigation, mobile phone manufacturers have been actively installing navigation modules and software that have been developed for a long time.
I originally wanted to try out the function in an extremely poor and backward place like Africa.
Unexpectedly, it came in handy.
Tao Guangming finally believed it, widened his eyes and asked, "Then why didn't you call him just now, causing me to walk for so long in vain?"
Li Wenjun pointed to the side and sighed: "We just walked so far, did you see a suitable landing place? No, it's either uneven or there are trees. Isn't this just a large enough flat ground?"
Yang Shouzhuo came over and took the phone and asked, "Our own satellite?"
In fact, he didn't know that Li Wenjun was looking at the positioning and navigation just now, and thought that Li Wenjun was just checking whether there was a signal on his mobile phone.
Li Wenjun said: "Yes. I feel it is not very accurate yet, maybe because the number of satellites is not enough. In the future, when there are enough satellites, it will be very accurate."
Yang Shouzhuo said: "In other words, drones, airplanes, and helicopters can all use our own satellite navigation."
Li Wenjun said: "Yes. It's OK. Last year, it was OK after three positioning and navigation satellites were launched in succession. I also came out with a test mission this time."
Yang Shouzhuo knew about the positioning of the navigation satellite, but he did not tell Li Wenjun.
Everyone who knows has signed a confidentiality agreement.
After all, we didn’t know yet whether it would work or not, and the fewer people knew about it, the less they knew.
Li Wenjun was only informed a few days before departure.
Yang Shouzhuo grabbed Li Wenjun's shoulders, shook him hard, and said in a hoarse voice: "That's great. Thank you."
In fact, they had everything ready the year before last, except for the rocket engine. Otherwise, he would not be so anxious and urge Li Wenjun to go to Russia.
If Li Wenjun hadn't helped them get experts and rocket engines from Russia and Ukraine last year, they would have had to wait at least five years before they could succeed.
With this navigation, they will no longer have to rely on maps and manual direction identification in future field operations.
Even in extreme conditions, such as total darkness, the target can be found accurately.
Tao Guangming had no idea what this meant, and naturally he couldn't understand why Yang Shouzhuo and Li Wenjun were so excited.
Li Wenjun's cell phone suddenly made a dull beep sound, then the screen went black and it turned off.
Tao Guangming was very nervous: "What, the battery is out?"
Li Wenjun sighed: "Yes, the positioning and navigation is very strong, but it consumes too much power. I have to go back and ask the battery research institute to figure out how to increase the battery capacity. It is too useless."
The key is still very hot, the navigation font is too ugly, and it often freezes.
There are also color LCDs, which are really terrible.
Well, there are still many problems. When I go back, I must give the guys in the mobile phone factory and the IT department a hard time.
Tao Guangming said: "It's over, the power is out. What if they can't find us?"
Li Wenjun thought for a while and said, "Why don't you pee on the ground to help? You drank the most water along the way."
Tao Guangming hesitated for a moment and said, "Would it be possible to write SOS with fewer strokes?"
Li Wenjun couldn't hold back his laughter: "Nervous, you really want to draw a distress symbol with urine. Is there a possibility that the pilot also has a new version of the positioning phone in his hand? Then he received my positioning mark and directly followed this Mark just comes to us. It doesn't matter if my phone is turned off or not."
Then a helicopter flew toward them out of the sunset.
Tao Guangming was stunned and murmured: "Damn it. He really found us."
He laughed, jumped up and waved: "Here, we are here."
In the past, he always felt that the aircraft factory's helicopter test flights were too noisy, but now he felt that the roar was the best sound he had ever heard.
Yang Shouzhuo directed the helicopter to land.
As soon as the helicopter stopped, Tao Guangming climbed up on his hands and knees, shook hands with the pilot enthusiastically, and was closer than seeing his relatives, and then slumped in the seat: "Go home, I can finally go home."
Yang Shouzhuo slowly came up and sat down, and sneered at Tao Guangming: "You are nothing."
Tao Guangming: "Xuxu, just go back and exercise. As long as you let me go back, you can ask me to do a triathlon."
The helicopter slowly took off in the sunset and flew towards Cape Town.
The sun in the distance appears larger and redder as it gets closer to the ground, like a red egg yolk falling slowly in the dense airflow on the ground.
Various wild animals and plants turn into golden silhouettes against it.
After refueling once, Tao Guangming refused to come down for fear of being left behind again.
When he arrived in Cape Town, Tao Guangming had a meal and a drink, then took a good bath and had a good sleep.
The iron pot stew that I thought was so ordinary before has now become extremely delicious.
Gold silver nest nest as their own kennel.
My home is like heaven compared to this place.
Ah...I'm back.
That's great.
Tao Guangming thought drowsily before falling asleep.
When he woke up in the morning, he was in particularly good spirits. He greeted Li Wenjun and others enthusiastically and asked, "Have you bought your plane tickets? When will you go back?"
In the past, he was responsible for the air tickets in China.
After he came out, Li Wenjun was in charge.
After all, the names of those airports were dazzling, and he was afraid that he would buy the wrong one.
Li Wenjun said: "Lao Tang called yesterday and told us to go to North Africa."
Tao Guangming was stunned and asked, "Why?"
Li Wenjun said: "Because the two tribes of Sudan suddenly started fighting, they were detained."
Tao Guangming gritted his teeth and thought: I'll go, I thought he would save me, but in the end he asked me to save him.
He hesitated and asked, "Want to get some guys?"
Tang Zhaonian's cargo ships usually have guns and other items. It's better to get a few things than nothing.
