Which is better in satellite technology? China's satellites are three times stronger than Russian ones. What are the benefits?

Satellite technology is the strongest in America.

Its advantages are as follows:

The combination of separation and unity

The recoverable satellite No.3 is the second generation photographic mapping satellite, and the recoverable satellite No.4 is a detailed land survey satellite. According to the different use requirements of high-precision photogrammetry and detailed land survey, scientific and technical personnel designed the overall scheme of these two models respectively, while the same subsystems and equipment were designed and manufactured in a unified way, which not only ensured the overall design level of the models, but also greatly improved the efficiency of manufacturing, testing and flight missions.

Instrument cabin expansion

The recoverable satellites No.3, No.4 and No.8 are basically the same in configuration, and consist of a cylinder, a frustum and a spherical head. The recovery module maintains the mature aerodynamic shape and design method of the original recoverable satellite, has good reentry stability and adapts to the ballistic reentry of the recovery module. The brake compartment remains in its original configuration.

Compared with the recoverable satellite 2, the section and volume of the instrument cabin columns of the recoverable satellites 3 and 4 are increased, which greatly improves the payload and battery loading capacity.

At present, China's Beidou satellite technology still has some shortcomings, and it has not been widely popularized free of charge like the United States. However, there are some good results. The performance of the self-developed chip used in Beidou system has surpassed that of the United States. In terms of accuracy, China stands out. The satellite error of 0.5 meters not only exceeds that of Russia, but also is only one step away from the United States.

The following are the nine technical features of Beidou:

1, tri-band signal;

2. Active positioning and passive positioning;

3. SMS communication service;

4. Domestic monitoring;

5. Step by step;

6. Local strengthening and gradual maturity;

7. Positioning accuracy;

8. Promote the upgrading of the whole manufacturing industry;

9. The construction speed is fast.
