Domestic independent research and development of satellite communication technology has made a new breakthrough to achieve continuous and stable measurement rate of 505Mbps.

CTOnews.com, November 5, according to the Aerospace Science and Industry official, the new generation of domestic broadband mobile satellite communication system developed by Hangzhou Space Engineering Network Technology Development (Hangzhou) Co., Ltd. (referred to as "Space Network Company") under the Aerospace Science and Industry Group has been verified by outfield Leo satellite tests a few days ago.

▲ source: space network company CTOnews.com learned that this test is based on the high-throughput broadband mobile satellite communication technology independently developed by Galaxy Aerospace in 2020.

According to reports, this test realized fast channel acquisition for the first time in satellite-to-ground docking, lasting uninterrupted communication for 6 minutes and 40 seconds, while achieving a continuous and stable measurement rate of 505Mbps, reaching the highest measured record publicly released in China.

The Space Network Company said that at present, it has completed the independent research and development of a new broadband satellite communication protocol for the integration of high and low orbits. it has overcome the technical problems such as large-scale and large dynamics of time and space, Doppler frequency shift, fast switching, high-frequency spectral efficiency and ultra-high transmission rate.
