China’s first private 5G low-orbit broadband satellite has passed factory tests and is expected to be launched at the end of the year, chinanews.com reported. The 5G satellite is expected to be put into orbit via Kuaizhou-1A (KZ-1A) rocket by the end of December.
It is China’s first satellite developed by a commercial aerospace company GalaxySpace and weighs approximately 200 kg. The launch will be the first Q/V band and 200-kilogram private (non-government owned) satellite.
With an orbit altitude of 1,200 meters, it will cover 300,000 square kilometers, roughly equivalent to 50 Shanghai cities. The satellite will gradually provide 5G signal services to various places through ground stations. From this starting point, China has taken the first step in its 5G “space communications” journey.
The satellite, made by Galaxy Space, will be launched via the domestically made KZ-1A carrier rocket at the end of December. Xu Ming, founder of GalaxySpace, said the launch of the satellite could mark the first step of its “space internet” project. The company wants to develop more low-cost, high-performance 5G satellites in the future, so as to fill digital gaps and connect the world with the 5G satellite network, he added.
“The coverage of 5G signals from the sky is huge, and the signals of each 5G low-orbit broadband satellite can evenly cover a range of 300,000 square kilometers. Large cities such as Beijing, Shanghai, Guangzhou, and Shenzhen can easily achieve full coverage for autonomous driving, aircraft, ships, high-speed rail And other mobile platforms to provide high-speed, stable, low-latency 5G network connection services. “Liu Chang said.
“China Telecom has proposed to promote the integration of mobile phone communications and satellites through software and hardware technologies such as mobile phone multi-mode.” Biqi, the chief expert of China Telecom and a member of Bell Labs in the United States, who is participating in the World 5G Conference, told reporters that Among the operators, China Telecom is currently the only operator with satellite spectrum related resources.
In order to make commercial use of 5G satellite signals as early as possible, Liu Chang said that Galaxy Aerospace is indeed expected to cooperate with operators.
Low-orbit broadband communications satellites could overcome challenges that ground base stations currently confront in covering areas such as deserts and the ocean, and shed light on those living in places where communication signals rarely reach, the report said.
