Chapter 720: Very good! But not good enough

They had forgotten to save their energy, and rushed forward in two steps at a time, rolling and crawling.

They rushed to the water, but did not drink it. They had just eaten, and the 100 ml of water in it was enough to last for a while.

The soldier put down his backpack and took out an aluminum lunch box containing a set of rapid testing reagents.

The Type 61 protective carrying gear is one of the few new equipment they have replaced. For them, the Type 61 can allow them to move more freely while further enhancing their carrying capacity.

Having water does not mean that you can drink it directly. This land is classified as saline-alkali land, and Haloxylon ammodendron trees can withstand salty water with a salt content of 1% to 3%.

Of course, even if it is undrinkable alkaline water, they have ways to process it into drinkable water.
The two of them cooperated with each other and moved skillfully, and soon, the rapid test results came out.

Drinkable!
However, the two did not drink it. Although they were not thirsty now, they could not drink raw water in the wild unless it was absolutely necessary.

Both of them felt relieved. Based on the amount of supplies they carried, they didn't have to worry about any problems for the time being. The only problem now was how to bring this good news back to the camp.

"Squad leader, let's use the walkie-talkie to call the camp. Even if they can't find us, we can use the gunfire to attract them over."

In order to save as much weight as possible, the two of them only carried a semi-automatic gun and a small amount of ammunition. The other semi-automatic gun was replaced by a walkie-talkie of almost the same weight. Excluding ammunition, both weighed about 3kg, which was just right.

In fact, they all knew that the straight-line distance from the camp might not be very far, but sometimes even a few kilometers away seemed like an insurmountable chasm. They were now lost and could not determine their location, nor could they clearly communicate on the walkie-talkie.

There are many cases where the walkie-talkie can get through but cannot be found.

The squad leader, however, was confident and not in a hurry at all.

"No need for guns. Sandstorms could hit here at any time. Gunshots may not be heard in the wind and sand, and the distance is uncertain. This method may put our comrades in new dangers."

"What should we do? Are we just going to walk back and report? If something goes wrong on the way, we'll be fine, but we'll lose the information about the water source."

The squad leader smiled and said, "I have a new weapon here. Hehe, it was given to me just before I set out. They said it had just been delivered. Let me try it first. If it doesn't work, we'll talk about it later."

Under the curious gaze of the soldiers, the squad leader took out a small canvas bag from his backpack and took something out of it.

It looks a bit like a walkie-talkie and also has an antenna, but its size is less than one-third of a walkie-talkie. Judging from the ease with which the squad leader holds it, it is probably even lighter.

The squad leader unfolded the manual and said, "The comrade in charge of the equipment said that this thing must be used in emergencies and cannot be turned on at other times."

The instruction manual looked like it was printed temporarily, and the heading was "Trial-produced triangulation life-saving beacon machine".

The soldiers didn’t understand much else, but they could still understand the word “lifesaving”. It seemed that it was specially used for this situation. No wonder it couldn’t be turned on at normal times.

The instruction manual was very short, and the squad leader read it in a few seconds, then handed it to the soldier: "You should also learn it. In case of any accidents, you will have to operate it."

The soldiers found it new. Which of these new equipments didn't require special learning and training? Why did this thing seem like a joke?

He took it and looked at it, only to find that the operation of this thing was really damn simple.

The core is three steps: turn on the power, select the current status - the green button is good, the yellow button is critical, and press the red button to send.

That’s it. It’s that simple. You don’t have to do anything else or say anything else. The only thing left is to check the status of the indicator light.

The indicator lights look small and I don't know if they are clear enough.

Well, it turns out that anyone can learn this.

The squad leader took out a pack of self-heating individual rations from his bag and put it into the socket of the bulletproof plate - there was no need to insert the bulletproof plate here, and this socket was used as a pocket by them. He also took out a first aid kit and put it into the carrying gear.

"You take three rations and your gun. Leave everything else here. We're going to the highest point nearby."

The instructions say that if conditions permit, this thing should be used at a commanding height for best results.

The commanding heights were not far away, and the two men brought a gun, a first aid kit, and four rations, which were enough to deal with emergencies.

Although it was not far away, it took them almost half an hour to climb to the top of the dune.

The squad leader took out the beacon and turned on the power. The signal indicator window changed from red to yellow and soon turned green.

The two didn't know what the principle was. They only knew that according to the instruction manual, this meant that the signal conditions of the beacon were good.

The squad leader pressed the status button 1. The current status was very good, and a water source was found. It couldn't be better. Then he pressed the send button. The send indicator light flashed red quickly. In less than a second, it was almost the same time for human senses. A green indicator light marked "receive confirmation" lit up.

In fact, as long as the signal is above a certain threshold, this simple automatic system, which only has a small amount of data to send and simple calculations to be performed throughout the process and has no actual mechanical actions, is just that fast. All the card-stuck-at-the-last-second scenes in the movies are used to cheat money and it’s too annoying to watch them too much.

Steady!

According to the manual, this light turns on to indicate that your location and distress signal have been accurately and completely received by the base, and a corresponding rescue will be launched immediately.

The two men laughed happily. From that moment on, they were no longer afraid. Even if something happened to them, the comrades who came to search and rescue would be able to find this source of water and fuel.

They were completely relieved. What were they still standing there for? They were eating! Climbing this slope was quite tiring. The sliding sand made them move forward and backward three times. They had to replenish their energy.

Just as they pressed the launch button, in a newly arranged room in the base, a computer was running and the person on duty was sitting next to it.

The computer's buzzer suddenly issued a "beep beep" alarm sound, and this alarm will continue to sound without human intervention.

The staff on duty was startled. The computer rang, indicating only one thing: a comrade was lost in the desert!

His hands immediately went to the keyboard and his eyes looked at the monitor.

After just a glance, he picked up the phone next to him.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

"Report, beacon No. 19 is calling for help. The person calling for help is in good condition and has replied to the reception confirmation signal. The coordinates are..."

After receiving the report, the base commander on duty immediately began to organize rescue.

"Who is using beacon No. 19?" Although it is a trial beacon, the number distributed is not small. After all, as long as this thing can achieve the expected effect, it is really useful. Even in the trial period, it can add an extra layer of protection for the lives of comrades working outdoors. It is worthwhile to build two signal towers specifically for this system.

What signal towers need is steel, and for the base, this thing is really not in short supply this year.

"It's on the tower where the explosion occurred. They are a new construction site, so the probability of similar problems occurring is higher."

At this time, the comrades working on the map had quickly completed their work: "Report, they are about 7 kilometers southwest of the explosion point tower."

"So far? It seems they got lost while looking for water." The tower where the explosion occurred was already far enough away, and the rescue workers had to go even farther.

"Search and rescue team, take the real-time positioning device and set off!" The commander immediately gave the order.

Two 230-type four-wheel drive off-road vehicles were quickly loaded with personnel and equipment and set off to the rescue site. They had to rush to the explosion point tower first, and then start a foot search and rescue from the explosion point tower.

……

The Defense Work Committee quickly received a report on the incident. After reading it, the chief engineer seemed to be thinking about something and walked to the leader’s office with the report.

"Leader, the triangulation positioning system was successfully tested in the desert. We found two soldiers who got lost after finding a water source deep in the desert."

"Great! Taking action is saving lives! Gao Zhendong's proposal to use triangulation for tactical-level troop positioning and popularize small positioning terminals seems to have great application prospects." The leader said happily after reading the report.

The chief engineer nodded with a smile: "Yes, especially after he developed the integrated circuit technology, it created conditions for the miniaturization and low cost of terminals. Digital communication technology also provided a channel foundation for complex data transmission. Taken together, it is a natural progression."

Triangulation positioning is not something new, but if it is to be popularized at the tactical level, especially in front-line combat teams, miniaturization, low cost and digital transmission are indispensable.

The leader of the Defense Work Committee nodded with satisfaction. As someone who had commanded thousands of troops, he knew very well how great the prospects of this thing were. It could be used to save lives and to kill enemies.

"Unfortunately, the triangulation positioning system is complex and affected by the curvature of the earth. It is severely limited in mountainous and hilly areas. Even in plains, the ground positioning range is only tens of kilometers." The leader felt a little unsatisfied.

"It seems that the aerial relay single-point positioning that Comrade Gao Zhendong once proposed really needs to be put on the agenda. According to Comrade Zhendong's expectations, this thing can provide aerial positioning for hundreds of kilometers. Just for this reason, the Air Force has been coveting it for a long time, not to mention that it can also provide positioning for a large area of ​​ground forces." The chief engineer smiled.

"Notify the research units of the triangulated positioning system. Both the deepening of the triangulated positioning system and the implementation of the single-point positioning system must be accelerated!" the leader said in a decisive tone.

In a certain electronic research institute, the chief engineer of the institute received an email from the Defense Work Committee.

After reading it, he laughed and walked into a multi-person office next door.

"Comrades, we have a real case for the finalization test of our regional triangulation positioning system."

Everyone stopped what they were doing and looked at their chief engineer with burning eyes.
