When USS Harry S. Truman was heading to a strait transit drill off the coast of Long Island in New York on June 17 last year, a Chinese remote sensing satellite powered by the latest artificial intelligence technology automatically detected the Nimitz-class aircraft carrier and alerted Beijing with the precise coordinates, according to a new study by Chinese space scientists.

In the past, the Chinese military had to collect and analyse a huge amount of raw satellite data on the ground to get a clue on the details of such drills taking place in the US home waters, and the results usually came after the event was over.

But with AI-powered satellites, Beijing could detect and “live stream” military activities or assets of interest on the other side of the planet, according to space scientist Yang Fang and her colleagues with DFH Satellite in Beijing in a paper published in domestic peer-reviewed journal Spacecraft Engineering last month.

The satellite that caught the US aircraft carrier in the act was so smart, it could identify a wide range of tactical or strategic targets by analysing more than 200 frames of high-definition images per second, a speed that some ground-based computers would struggle to achieve, according to the Chinese team.

Yang’s team said that they had achieved a breakthrough on “weight reduction” for AI technology. The image recognition with the algorithm they developed for the satellite consumed just 3 per cent of the calculation resources used by traditional algorithms when doing the same task, according to their paper.

In another test to verify the performance of space-based AI, the same satellite automatically detected and obtained the coordinates of military aircraft, naval ships and strategic assets such as oil storage tanks in northeastern Australia.

Illumina ordered to pay BGI subsidiary $333 million in DNA-sequencing patent case​

(Reuters) - A Delaware jury on Friday ordered Illumina Inc to pay more than $333 million to a U.S. unit of Chinese genomics company BGI Group after finding that Illumina's DNA-sequencing systems infringed two patents.

The jury also said Illumina infringed the patents willfully, and that three patents it had accused BGI's Complete Genomics unit of infringing were invalid.
