Original title: the first 5g satellite is expected to be launched this month
China's first private 5g low earth orbit broadband satellite with a communication capacity of 10Gbps has been officially delivered from the factory. It is expected to be launched by the end of December with kuaizhou-1a rocket.
It is understood that the satellite is the first Q / V band satellite independently developed by China's commercial space company Galaxy aerospace, and also the first 200 kg satellite developed by China's commercial space company. Its orbit altitude is 1200 km, and a single satellite can cover 300000 square kilometers, equivalent to the area of 50 Shanghai cities.
Satellite factory status is an important stage of satellite development, which marks that the satellite hardware and software are all in the state of solidification. The successful delivery of the first Galaxy space satellite means that the ground test of China's first Leo broadband satellite with communication capacity of 10Gbps has entered a stable and reliable technical state.
Xu Ming, founder, chairman and CEO of Galaxy aerospace, said that from the first launch, Galaxy Aerospace will step out of the first step of "space Internet". In the future, Galaxy Aerospace will develop and produce low-cost and high-performance 5g satellites on a large scale, build a space Internet, bridge the digital divide, and connect the 5g satellite network with every corner of the earth.
In recent years, oneweb and SpaceX have taken the lead in the layout of LEO communication constellation. In terms of communication bandwidth design, Galaxy Aerospace benchmarked the world's leading technology, and realized the technology benchmarking international 10Gbps communication capability for the first time on domestic private low orbit broadband satellites.
In fact, although the 5g era has begun, the current global network coverage is still facing great challenges. It is difficult for ground base stations to cover deserts, oceans and other areas. Leo broadband communication satellites can solve the problem of global network coverage and access, and it is expected that 4 billion people in the global information poverty can enjoy the network world.
In the near future, people will brush short videos on airplanes and make video phone calls. In addition, due to the convenience of radio operators, the speed of satellite communication will be lower in the future.
Zhang Shijie, partner of Galaxy aerospace and satellite technology expert, said: "with the rapid development of global commercial communication satellites, it is very important to lay out the satellite frequency orbit in advance. It can be predicted that the demand for low-frequency resources will continue to grow and resources will become increasingly tense. Only when China's commercial aerospace companies deploy high-frequency band communications as soon as possible, can they change lanes and overtake vehicles in the international arena. As the first low orbit broadband satellite independently developed by a Chinese private company, the first Galaxy Aerospace Satellite is of great significance. '(end)
