China has successfully launched! What are the advantages of the Qianfan Constellation low-orbit satellites: low cost and large bandwidth

08/06 2024 328

According to Fast Technology on August 6, today, China successfully launched the first batch of networking satellites of the "Qianfan Constellation" - 18 Qianfan Polar Orbit 01 satellites - into space using the Long March 6A carrier rocket at the Taiyuan Satellite Launch Center, and the satellites successfully entered their Pre booked track s.

It is understood that the Qianfan Constellation is also known as the "G60 Starlink" project, led by Shanghai Songjiang District in collaboration with multiple capital partners. The main implementation entity of the project is Shanghai Huanxin Satellite.

According to the plan, by the end of 2030, the "Qianfan Constellation" will ultimately establish a low-orbit broadband multimedia satellite network consisting of over 10,000 satellites.

Positioning high-throughput broadband communication satellites with a flat panel design in low Earth orbit offers advantages such as proximity to Earth, low cost, low power consumption, wide coverage, and low latency, enabling the provision of large bandwidth, low latency, high-quality, highly secure, and globally accessible satellite internet services.

According to CCTV News, Zhu Xiaocheng, Deputy Commander of the Qianfan Constellation, explained that there is a square relationship between communication speed, satellite power consumption, and distance. The further the distance, the lower the corresponding speed.

If we were to operate at a higher orbit, such as geostationary orbit at an altitude of 36,000 kilometers, although global coverage could be achieved with just three satellites, the communication speed under such conditions would be very low.

"Big data transmission necessitates a low-orbit broadband communication network system. Based on the orbital coverage design requirements, our analysis suggests that approximately 14,000 satellites would suffice to cover most of the inhabited areas," said Zhu Xiaocheng.
