One Arrow and Seven Stars my country will set up a low-orbit broadband communication test constellation
Science and Technology Daily, Beijing, March 5th (Chen Yijun, Yuan Xiaojie, reporter Fu Yifei) At 14:01 on the 5th, the Long March 2C carrier rocket developed by the First Academy of China Aerospace Science and Technology Corporation was ignited at the Xichang Satellite Launch Center and successfully launched. The 02 batch of 6 satellites of Galaxy Aerospace Company was sent into the predetermined orbit, and the launch mission was a complete success.
The mission also launched a micro-nano satellite.
The reporter learned from Galaxy Aerospace that the 02 batches of mass-produced satellites launched this time are low-orbit broadband communication satellites independently developed and mass-manufactured by the company.
These 6 satellites will form a low-orbit broadband communication test constellation together with the first satellite of Galaxy Aerospace, and build a satellite-ground fusion 5G test network "Little Spider Web", with a single uninterrupted, low-latency broadband communication of about 30 minutes The service capability can be used for technical verification of my country's low-orbit satellite Internet and the integrated space-earth network.
According to Li Jun, the chief designer of the first two-C rocket model, this launch is the first center-bearing cylinder side-mounted multi-satellite network launch for the two-stage configuration of the Chang-2C rocket. In addition, there are many new technologies, Combined application of the new state.
Li Jun said that during the mission, the test team actively coordinated, rapidly iterated, and determined the system interface in a short period of time; the satellite requirements were realized by integrating mature sub-technologies and products as much as possible, reducing the amount of system design and test verification, thus greatly shortening the mission response period ——The launch service contract will be officially signed in May 2021, and the launch will be completed in March 2022, setting a mission response record.
