"Because its altitude is only about 100 kilometers to 200 kilometers, we can launch it with a light carrier rocket, and we can also use some missiles to launch it if necessary. These are all possible."

Although Zhang Xiaolei did not expand on this aspect, everyone understood what she meant. In fact, many missiles can reach this height, so this means that such missiles can be used to launch if necessary. In this way, a large number of such satellites can be quickly deployed in the air to carry out positions and supplement the losses and vacancies of medium and large satellites.

At the same time, this also means that it no longer needs a special launch site, and emergency launch tasks can be completed in a field environment. And its launch preparation time will also be greatly shortened, because all solid rockets are already loaded, and there is no need to refuel like conventional liquid launch vehicles.

So Zhang Xiaolei's words were naturally recognized and affirmed by everyone present.

Zhang Xiaolei, who received such positive feedback, turned up her mouth and continued to introduce.

"In addition to these advantages, our special operations support satellite also has a unique advantage, that is, it is cheap, very cheap.

These microsatellites use our general-purpose satellite platform, and then add different functional modules to it according to needs, which also means that this satellite platform can be mass-produced, which not only can increase the output of this satellite, but also can greatly increase the production capacity of the satellite platform. Greatly lower the cost price of this satellite platform.

As a result, they are more than half or even lower than the cost of micro-satellites of the same level. This also means that the cost of manufacturing and using these satellites will be very cheap and suitable for large-scale use.

Compared with medium and large satellites, its cost is negligibly low, and even the cost of a satellite is much lower than the cost of one orbit change of a medium and large satellite.

If we can use our Jianmu-2 launch vehicle for launch, then its cost can be reduced to a lower level, which is far lower than the level of using other similar types of reconnaissance and communication equipment. "

After listening to Zhang Xiaolei's introduction, everyone nodded involuntarily. Indeed, cost is the key, and it is also the most concerned by everyone. Hearing Zhang Xiaolei say that the cost of this satellite is very cheap, everyone couldn't help smiling.

However, some special forces members couldn't help asking: "How low can it be?"

Hearing this question, everyone present couldn't help laughing, and they also rejoiced at the straightforward question of the special forces member. Indeed, this is a question that many people want to ask.

In this regard, Zhang Xiaolei was not angry or flustered, but replied with a smile: "If it is a one-kilogram cubesat, we can reduce its price to about 10,000 yuan. Adding its launch cost, overall It will not exceed twenty thousand yuan."

so cheap? Hearing Zhang Xiaolei's words, everyone couldn't help being surprised.

The price is indeed beyond everyone's imagination. You know, a better mobile phone now costs seven to eight million yuan, but such a satellite costs less than 20,000 yuan, and the launch fee is also included.

You must know that the reason why satellites are expensive is of course because of their relatively high development costs on the one hand, and of course because of their high launch costs on the other hand.

But now, such a satellite only costs less than 20,000 yuan, which is beyond anyone's imagination.

Therefore, even Wang Lianggong and Li Weiguo showed disbelief when they heard the number, and then looked at Wu Hao waiting for his confirmation.

As for Wu Hao, he did not disappoint everyone, and nodded immediately and said: "It is true that a one-kilogram cubesat can achieve this price, but if you want to add other functional modules, you must add another price.

Such as communication module, radar detection module, optical lens module and so on. The functions of these modules are different, and the prices are naturally different. The cheap ones are of course very cheap, but the expensive ones are definitely expensive.

Many of these modules are not our own, so the price is out of our control. However, as the output increases, we can further compress the prices of these modules.

As for the launch cost, you don’t have to worry. The low-earth orbit carrying cost of our Jianmu-2 rocket can be controlled to about 10,000. If there is a large amount, the launch price may be even cheaper. "

Hearing Wu Hao's confirmation, everyone present became uneasy. When did satellites become so cheap? This made it difficult for everyone to digest for a while.

If this is the case, these support satellites specially built for special operations are really as good as Zhang Xiaolei said, then they can be used in special operations and play a huge role in special operations.

"The cost of these tiny satellites is so low, what is their performance, and how long can they work?" Luo Kai asked this time. He asked a very professional question, and it was also a question that many people present wanted to ask. .

Indeed, if the price is so cheap, everyone is concerned about their performance.

Hearing Luo Kai's question, Zhang Xiaolei replied with a smile: "Don't worry about the performance, the performance of these microsatellites is basically the same as that of ordinary microsatellites, and even better than the performance of these conventional microsatellites.

For example, this reconnaissance and surveillance satellite uses our most advanced synthetic aperture fly-eye lens, which has a stronger photosensitive ability, so the resolution will be higher than that of lenses of the same level. Like this compound eye lens with an aperture of 30 cm, its resolution can reach the sub-meter level, and UU reading www.uukanshu.com can clearly see the movement of personnel on the ground, which is very suitable for performing some battlefield reconnaissance tasks. "

Yami class!

Hearing this number, everyone couldn't help being surprised. Although this resolution is not considered the strongest, because the resolution of many large reconnaissance satellites is much higher than this, and can even reach the centimeter level, and the license plate numbers of ground vehicles can be seen clearly. Satellites can clearly see news headlines on newspapers in the hands of ground personnel.

But for a satellite of this size, for a lens of this size, being able to achieve sub-meter resolution is really powerful.

Noticing everyone's reaction, Zhang Xiaolei smiled and continued to talk: "The working life of these tiny satellites in orbit is different, and it depends on the orbit.

In general, their working time can span from several days to several months, or even several years.

However, under normal circumstances, it is basically about a few months, which is also determined by the altitude of the orbit. "
