The voyage marked the first verification of networked communications in the Arctic, Antarctica, and the Qinghai-Xizang Plateau, also known as Earth's "Third Pole," and closed the last gap in global communications coverage, the expedition team said.

Organized by China's Ministry of Natural Resources, the expedition departed on July 3. Jidi, which means "polar region" in Mandarin, is one of the expedition's four research vessels.
According to the expedition team, sound and video were heard and seen clearly and smoothly during the video link connecting the icebreaker in the Arctic, Qinling Station in Antarctica, the Lhasa River test station in Xizang Autonomous Region, and a ministry bureau based in Qingdao, a coastal city in eastern China.
The link enabled low-latency, high-bandwidth global communications via China's satellite internet, while verifying its stability under harsh conditions such as extreme low temperatures, severe sandstorms, and ice fog.
The voyage also marked China's first use of domestic satellite internet for medical support at the poles. The Arctic Ocean expedition team said Jidi had conducted high-resolution ship-to-shore video consultations with hospitals and experts in Qingdao, allowing for timely medical assessments for its members.
Another achievement during the voyage was a domestically developed Chinese ocean buoy called Zhigan, which for the first time allows Chinese survey equipment to have full control over data collection and transmission. Because its transmission speed and quality met practical requirements in trials, the buoy offers an alternative to the current use of international satellites for real-time ocean sensing data transmission.
