The impact of X37B on China s Beidou How China should respond

X37b is the space shuttle plus two claws! At the beginning of the war, China knocked this thing down with a few missiles.

How to prevent it, my personal plan is there, all countries should, when launching a satellite, carry 20 kg of TNT explosives on the satellite, this X37B is a manned space shuttle... The training cost of an astronaut is n times the same weight of the body**, 20 kg TNT can't even blow up a tank on the ground, but it is completely enough to blow up the incomparably expensive X37B, and it will be detonated when it is found that the satellite is caught by X37B! Fried smashed!

Hehehe, you're overthinking. The Big Dipper is not yet global. Our Beidou still has to develop well. However, our laser technology has always been amazing! If that's true, then we don't have to care too much about x37b!

No one knows exactly what the X-37B's mission payload is, and it seems most likely that it will be reconnaissance equipment. But the planned payload could be to refuel the satellite with a robotic arm or replace a solar panel. The US-212 that returned the day before yesterday is likely to be a flight test and has no mission payload.

While the launch exists in some people's imagination, there is little evidence that the current design is intended for this purpose. It is also too wasteful to use hundreds of days of self-sustaining power and high launch costs for a one-time ** launch. There is little need to deal with any of the existing targets from the universe at the moment.

There is no impact. The US aerospace advantage is too great, and other countries will not have any influence on the US advantage, and in turn, the US advantage is not something that other countries can counter.

First of all, the lowest satellites used by the four major satellite positioning systems are at an altitude of about 20,000 kilometers, and there is no *** that can be hit at present.

Secondly, Beidou's satellite orbit is the highest among the four major systems, and it is also the most difficult to hit.

Third, Beidou is a dual-mode system, even if you shoot down all 27 satellites in the middle earth orbit, its positioning accuracy will be reduced by about double, even if you shoot down the satellites in oblique synchronous orbit, as long as there are more than two geostationary orbit satellites left, it can still be positioned.

So Beidou is the most difficult of the four major satellite navigation systems to destroy. GPS is basically useless as long as 6 or 8 satellites are knocked out. As long as there are more than 2 of the 35 Beidou satellites left, they can be used.

In fact, the biggest disadvantage of the Beidou system, including other navigation systems, is the lack of geostationary orbit, because the number of geostationary orbits is limited, and the United States occupies it first, so we can't use this section of the orbit satellite and the earth are in relative motion, so the algorithm is very complicated and will affect the accuracy.

The most important thing is that it is independently developed by our country and will not be controlled by others, and it is very important for the training of technical research and development personnel, the strength of the country, the image of the outside world, and the needs of war.

China's self-developed "Beidou operation service platform" was officially opened, which marks that China has completely owned. What are the advantages and disadvantages of BeiDou compared to Global Positioning System (GPS)? What is the market outlook? Reporter.

Wright's "Beidou GNSS Geological Landslide Monitoring System" adopts Beidou + GPS and other multi-system joint positioning and monitoring to carry out 24-hour real-time deformation monitoring of the mountain, intelligently assess its safety status, and give early warning of possible landslide dangers. As early as 2013, the Beidou + GPS dual-star system was adopted on the inlet high slope of the flood discharge cavity of the Changheba Hydropower Station in Sichuan Province to realize millimeter-level displacement monitoring of external deformation. This satellite monitoring system can grasp the data in real time even when the hunger fight is in heavy rain, **, mudslide landslide, and provide people with early warning information.

Hello! Beidou Navigation Satellite System is committed to providing high-quality positioning, navigation and timing services to users around the world, including open services and authorized services. The open service is to provide positioning, speed measurement and timing services to the world free of charge, with a positioning accuracy of 10 meters, a speed measurement accuracy of meters and seconds, and a timing accuracy of 10 nanoseconds.

The authorized service is to provide positioning, speed measurement, timing and communication services, as well as system integrity information for users with high-precision and high-reliability satellite navigation needs. Navigation accuracy is not inferior to Europe and the United States, Beidou satellite navigation system solves the problem of who, what, where, this is the characteristic service of Beidou, you can go all over the world by a terminal of Beidou.

For our country, we will first solve the problem of whether there is a problem, and then talk about anything else.

A few days ago, the Beidou global network was completed, but the global accuracy is not high, and the accuracy of the earth in the Asia-Pacific region is relatively high. It is mainly limited by technologies such as atomic clocks, which cannot be compensated for by the number of satellites. The gap will also increase in the process of updating the third generation of GPS.

It is meaningless to exceed, and the accuracy of the fit will be relatively high.

If China does not have Beidou and uses GPS, the United States will turn off China's GPS signal, and American ICBMs can blow China back to the Stone Age at any time.

China's Beidou navigation is better than GPS, first of all, China's Beidou is a system developed by adopting the advantages of various types of satellite navigation, and GPS is a system developed decades ago, its performance is limited by the technical level at that time, and it is worse than the satellite navigation system developed recently. Secondly, Beidou is a domestic system, which is much superior to the use of other people's systems in terms of safety, and the use of others is controlled by others after all, especially in emergency situations, such as war, blockade, and interference, GPS loses security.

Beidou is also a type of GPS. The United States deliberately named its GPS GPS with sinister intentions.

At present, Beidou is the best, and other countries are classic machines.

GPS and Beidou are the products of the same function, GPS developed earlier, and has now achieved global positioning with high accuracy. But China's Beidou is still developing, and the number of satellites is far less than GPS, in terms of accuracy, speed, are not as good as GPS, so according to the current situation, GPS is in an absolute position, but I also believe that China's Beidou will one day surpass GPS and become the global mainstream! Thank you, I hope you are satisfied with my answer.

When Beidou is used, you don't need to look at the old beauty's face, you can use it if you want. GPS, when you use it, Lao Mei will use it for you if she wants to, and if she doesn't want to use it, she won't use it for you. To sum up, no matter how good GPS is, you can only use Beidou.

ps: GPS is not much better than Beidou**, but there are more satellites and a little more accurate)

How is Beidou navigation easy to use: which is better than GPS? The answer is what you know.

GPS, there is a problem with the Beidou basic clock.

1. Comparison of positioning accuracy: Beidou's global positioning accuracy is comparable to GPS, and local areas are better than GPS. For example, in regions outside the Asia-Pacific region, the positioning accuracy of Beidou is about 5 meters, and in the Asia-Pacific region, it can be accurate to 3 meters.

2. Short message service: In addition to real-time navigation and fast positioning, the Beidou system's position report and short message communication and other special functions are not available in any other foreign global navigation satellite system.

3. The Beidou system is the largest and most extensive space system in China, with the widest coverage, the highest service performance and the most closely related to people's lives. As an important support for the country's economic and social development, the Beidou system is the third largest economic growth point after mobile communications and the Internet, with an average annual growth rate of more than 20% in the overall output value of China's satellite navigation and location service industry in the past 10 years, and the output value is expected to exceed 400 billion yuan in 2020.

4. The Beidou-3 system adopts the Ka-band phased array link, which organically links 30 satellites with dozens of domestic ground stations, greatly improving the operational capability, safety and positioning accuracy, and directly providing TT&C transmission services for spacecraft. Even without ground support, the satellite can achieve 60 days of autonomous operation, and the upper and lower links are not interfered with by the atmospheric ionosphere, and the positioning accuracy is significantly improved.

Of course, Beidou is okay, GSP has been in service for decades, and Beidou is not advanced enough.

It is recommended to use the Zhongletong network** The call is clear and stable, and it does not cost money, and it will not be intercepted, and other networks** will be intercepted by antivirus software. And only 2kb of traffic is required for the whole process

There is also a special international card, and at present, the domestic Letong can play an international network**.

The Beidou system has three major functions, short message, positioning and navigation, and timing. Civilian applications are as follows:

1. Short message application. It is used for data and communication transmission in uninhabited areas, such as the "Beidou Sea Chat", which is currently well-known in the circle of seafarers and outdoor travelers, is a communication application;

2. Positioning and navigation applications. More extensively, at present, many vehicles are required to install Beidou positioning navigation equipment, in addition, in many mobile phone products are compatible with Beidou positioning function. At present, most of the products on the market exist in the form of Beidou + GPS positioning;

3. Timing application. It is used in the communication and power industries to calibrate the system time and ensure the consistency of the system. In the past, the application of GPS was the mainstay, but now it has gradually transitioned to Beidou timing.

The navigation of the car belongs to the civilian use of the Beidou navigation system.
