After leaving Beidou, Dugu Shuai has been adrift, with empty ambitions, but nowhere to show them. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

After all, there are only four companies in the world to do the navigation system, two of which have basically succeeded, and one of them has collapsed in China.

The rest of the European Galileo navigation system, what people lack is not talent, not technology, but money!

Therefore, Dugu Shuai has been unemployed, but he has not given up his research on navigation systems.

Until the mortal starry sky recruited people, this guy didn't say a word, and came directly.

To put it bluntly, as long as you can develop a navigation system, even if you don't give money, you can just eat and live!

This made the employees of Mortal Star suspicious, and they only thought that this guy was a spy.

After some review, I found out that this guy has such a personality, there is no way.

After all, the person who advocates the sword demon Dugu seeks defeat has changed his name for this reason, and it would be strange if this person could be normal!

But even so, for the research work of navigation system, Dugu Shuai is quite accomplished.

Wang Fan made contact and directly appointed him as the leader of mortal navigation!

After solving these problems, Wang Fan began his retreat!

Now it is possible to engage in a navigation system, but it is not easy.

After all, the first three have robbed most of the high-quality tracks and frequency bands, and Wang Fan can no longer find another way to start now!

Just like the current business environment, those mature fields have long been rotten by their predecessors, and it is difficult for newcomers to want to enter without enough energy.

Therefore, many of the current entrepreneurship can only be emerging industries such as the Internet.

Similarly, Wang Fan's entire mortal navigation system also needs to find another way.

If you go the way of other countries, it will not be easy to go!

To this end, Wang Fan directly used the science and technology derivation system to establish a starry sky model, and imported the GPS of the United States, the Melonas system of Russia, the Beidou system of China, and the Galileo system of the European Union, all into the model, and derived a new system.

Even so, technology-derived systems still produce a large number of results in an instant.

But after Wang Fan screened for a while, there were only three suitable ones.

Others, either they can't meet Wang Fan's requirements.

Either the technical difficulty is too great, and the current technical level cannot be achieved at all.

Or rather, there are too many satellites, like having a navigation system that requires 100 satellites.

Wang Fan is really a dog, 100 pieces!

It's all money, and it takes time to launch!

You know, GPS needs 24 satellites enough, Beidou will eventually need 35, Russia's Melonas is also 24, and the EU's Galileo is 27!

The four add up, only 110.

Now a plan requires 100 pieces, and it is strange that Wang Fan agreed.

After another period of screening, Wang Fan finally chose a solution with the same 24 satellites.

Among them, there are four geostationary orbit satellites and 20 non-geostationary orbit satellites, all of which are staggered by the other four major navigation systems, and there will be no conflict.

More importantly, 20 of these 24 satellites can provide accurate global positioning services, and the other four are used as standby to deal with emergencies and emergencies.

After all, satellites have a lifespan, and there are accidents.

Therefore, if there is no substitute, in case the problem is exceeded, then the trouble is big.

In particular, the target of the mortal navigation system is unmanned driving on a global scale!

Of these 24 satellites, Wang Fan is ready to launch them in four batches, the first batch of 4, the second batch of 8, the third batch of 8, and the last batch of 4!

Since all the technical solutions have been derived, it will take more than a year to complete the layout. As long as there are no problems with policies, funds and production capacity!

The corresponding satellite design scheme has also been derived.

Compared with Beidou, GPS, etc., the satellites of mortal navigation systems are smaller in size, lighter in weight, more powerful, and more accurate, and even have a much higher lifespan than the most advanced level in the world!

For example, in terms of mass, the average mass of each satellite is only 0.5 tons, and his, the least, is more than 0.6 tons, and some even exceed 1.4 tons!

In terms of accuracy, the satellite accuracy of GPS is ±0.3m, the satellite accuracy of GLONASS is 0.5m-0.7m, Galileo is about 1m, the accuracy of Beidou is about 10m, and the satellite accuracy of the mortal navigation system is ±0.01m, which is one centimeter!

For example, GPS, the accuracy of stand-alone navigation is about 10 meters, and the accuracy of comprehensive positioning can reach centimeter level and millimeter level. It's just that the accuracy of the opening of the civilian field is about 10 meters.

For mortal navigation, the accuracy of stand-alone positioning is 1 cm, and the comprehensive positioning can reach the micron level, which can fully meet the demanding requirements of unmanned driving!

After all, even if a person drives a car, it is impossible to calculate the accuracy to the centimeter level, let alone the micron level!

Of course, if it is used in the military, it will be even more terrifying!

The lifespan of the Beidou satellite is only about 8 years, Russia is about 10 years, Galileo is about 15 years, and the satellite life of mortal technology is more than 25 years!

In terms of cost, GPS costs a total of 30 billion US dollars, Beidou does not know, and the Galileo navigation system needs more than 10 billion euros.

And the mortal navigation system, after the whole thing, will also cost about 15 billion US dollars, which is a lot of expenses!

There is no way, Wang Fan's requirements are high, the precision is high, the service is high, and the cost is naturally high.

Even if most of them are self-developed, they still need these!

After getting the navigation system done, Wang Fan began to build a new model.

24 satellites, launch vehicles also have to be engaged!

Wang Fan took Space X's Falcon-9 and Falcon Heavy as prototypes, derived them, and finally obtained two launch vehicles.

Wang Fan named it Starry Sky One, as well as Starry Sky One!

Star-1 is launched into low-Earth orbit (LEO) with a maximum payload of 35 tons and launched into geosynchronous conversion orbit (GTO) with a maximum payload of 15 tons.

The Star One is launched into low Earth orbit (LEO) with a maximum payload of 80 tons, launched into geosynchronous conversion orbit (GTO) with a maximum payload of 35 tons, and launched to Mars with a maximum payload of 26 tons.

Of course, the load capacity of Starry Sky One and Starry Sky One is much larger than that of Falcon 9 and Falcon Giant, and they can be adjusted according to the actual situation under the maximum load.

But if you reach the limit and want to be overweight even further, it is easy to have problems.

And whether it is Star One or Star One, it can be recycled again, thereby greatly reducing costs.

More importantly, not only the recovery of the first-stage rocket, but also the second-stage launch vehicle!

In contrast, Space X can only achieve first-stage launch vehicle recovery at present.

The rest, whether it is the United States, Russia, or China, will not be able to recover the launch vehicle for the time being!

Mortal starry sky, there is an absolute advantage!
