GalaxySpace will launch six satellites to test broadband internet technologies

GalaxySpace, a Beijing-based private satellite maker, plans to deploy six satellites into low Earth orbit before the end of March to establish a space-based internet network, the company said Tuesday.

The six communications satellites were recently transported to the Xichang Satellite Launch Center in Sichuan Province and are expected to be launched by a Long March 2C carrier rocket in the first quarter of the year, the company said in a statement. Press.

They will form an experimental communication network called “Mini Spider Constellation” to test broadband internet technologies. According to the engineers, users will have access to high-speed Internet service via satellite signals transmitted through gateway stations on the ground.

Each of the satellites weighs about 200 kilograms, has a large transmission capacity of several gigabits per second and uses several bands.

Design and production of the satellites began early last year and took just 11 months, GalaxySpace said, noting that in addition to their communications payload, the satellites are also equipped with remote sensing capable of taking photos and videos.

Satellite technology researcher and GalaxySpace partner Zhang Shijie said the Mini Spider Constellation will provide users with 30 minutes of continuous high-speed Internet access each time they connect their devices such as cell phones and laptops to the satellite system.

“The experimental network will help us test the capabilities and performance of our satellites in different environments, explore new Internet service solutions, and accumulate experience for larger-scale networking operations,” he said. he declared.

Established in April 2018, GalaxySpace has become a booming player in China’s private satellite industry, with its own smart satellite factory being built in Jiangsu province.

It launched its first satellite – GalaxySpace 1 – in January 2020 from the Jiuquan Satellite Launch Center in northwest China.

Widely regarded as the country’s first 5G-enabled satellite, GalaxySpace 1 has carried out numerous in-orbit tests with ground stations, greatly advancing the research and development of satellite internet technology, Zhang said.

The satellite is still operating and remains China’s most powerful low-orbit communications satellite as well as the largest spacecraft ever built by a private Chinese company.

In the near future, GalaxySpace aims to build a system of commercial satellites in low Earth orbit to provide high-speed Internet and other communication services with global coverage.

Internationally, commercial space giants such as SpaceX and OneWeb have been scrambling to develop and build low-orbit communications satellite systems.
