The Tiantong-1 satellite tv for pc collection, which started with its first launch on August 6, 2016, now contains three satellites in a geosynchronous orbit at 36,000km, overlaying your complete Asia-Pacific area.This breakthrough got here to fruition when Huawei Applied sciences launched the world’s first smartphone supporting satellite tv for pc calls in September of the earlier yr, main the best way for different producers like Xiaomi, Honor, and Oppo to comply with swimsuit, a South China Morning Publish report stated.
These technological developments have confirmed invaluable, significantly in emergency conditions the place conventional communication networks are compromised. As an example, through the 6.2-magnitude earthquake in Gansu province on December 18, affected people may keep contact with the surface world because of the satellite tv for pc name operate accessible on their smartphones.
“Direct satellite tv for pc connectivity for cellphones has develop into a brand new growth development, and satellite tv for pc communication will regularly develop into in style among the many normal public,” famous a crew led by Cui Wanzhao from the China Academy of Area Expertise. Their work, detailed within the Aerospace Science and Expertise journal, highlights the overcoming of great technical challenges associated to passive intermodulation (PIM), which might degrade the standard of satellite tv for pc calls.
By addressing the PIM subject, the crew has enabled exceptionally delicate reception capabilities within the Tiantong satellites, permitting them to select up alerts from normal smartphones with out the necessity for exterior antennas. This functionality is essential, particularly given the satellites’ publicity to excessive temperature variations and their operation throughout a number of frequency bands.
China’s developments on this discipline are securing its place as a pacesetter in satellite tv for pc communication expertise globally, heralding a brand new period the place geographic isolation not equates to communication isolation.
