According to foreign media reports, SpaceX has applied to the US government for approval to launch satellites that provide global Internet access services.
In a paper submitted to the US Federal Communications Commission (FFC), SpaceX elaborated on its plans to build a network of 4,425 satellites.
This is one of the few companies that are preparing to deploy satellite Internet services in the next few years.
In September of this year, SpaceX suffered a major setback, and one of its rockets exploded during the test.
In a statement, SpaceX claims that “once the full deployment is successful, the SpaceX satellite system will be able to cover all corners of the globe, providing global access to the Internet.â€
These satellites will orbit the Earth at an altitude of 714 to 823 miles (1150 to 1325 kilometers) from the ground. This height is higher than the International Space Station, but lower than the geosynchronous satellite.
Last year, SpaceX founder Elon Musk declared that the scale of the service "will exceed any project that people have talked about so far." He added that the service would require approximately $10 billion to start.
It is reported that the first 800 satellites will be used to expand Internet access services in the United States (including Puerto Rico and the US Virgin Islands).
The size of each satellite is comparable to the size of a typical car. If it does not contain solar panels, it weighs about 386 kilograms.
Since the explosion in September this year destroyed the $62 million Falcon 9 booster and the $200 million Israeli communications satellite, SpaceX's rocket launch program has been shelved. The company hopes to resume rocket launch next month.
CSRME safety controller is developed for standard GB27607. By monitoring machine tool safety related equipment, the security of machine control system can meet the requirements of GB27607, and its security meets the requirements of ISO13849-1 (PLe) and IEC61508 (SIL3).
With rich interfaces, CSRME has limited programmable function. It can simultaneously replace many different types of safety control modules or safety PLCs, thus greatly simplifying the safety design of machine control systems and reducing cost.
