The Weihai One Satellite Was Successfully Put Into Orbit! Can Be Star-ground Laser Communication Rate Up To 40Gbps

At 11:06 on February 3, 2024, by the Harbin Institute of Technology (Weihai) led the development of through the remote integrated satellite system "Weihai One" 01/02 star aboard the Jielong three launch vehicle in the sea near Yangjiang, Guangdong Province, ignited and lifted off, the satellite smoothly into the intended orbit, the launch mission was a complete success.
According to the "Weihai One" deputy commander-in-chief, project technical leader, Harbin Institute of Technology (Weihai), deputy dean of the College of Information Science and Engineering, Professor Wang Chenxu introduction, as the first domestic satellite constellation for the detection and identification of marine targets through the remote integration of the Harbin Institute of Technology (Weihai) led the development of the "Weihai One" satellite 01 star / 02 star, a single weight of about 95 kilograms, using a sun-synchronous orbit, orbital altitude of 520 kilometers. Star carrying star-ground / interstellar laser communication, high-resolution visible camera and other payloads, through the fusion of multi-source information and artificial intelligence identification technology, can realize the effective detection and identification of maritime targets.
"Weihai One" chief designer, Harbin Institute of Technology (Weihai) School of Information Science and Engineering Professor Luo Qinghua introduced: "'Weihai One' main advantage lies in the transmission rate is fast, star-ground laser communication load rate Up to 40Gbps, equivalent to every second can transmit a high-definition movie, is the traditional microwave dozens of times, reached the domestic leading level; instant remote sensing, with the help of interstellar laser link can be realized long-distance high-definition remote sensing information instantly, high-speed back to the transmission; Intelligent recognition quasi, visible light data and ship automatic identification system AIS terminal information for fusion, fast and accurate identification of ship identity information and posture, to ensure shipping safety, support maritime law enforcement. Ensure shipping safety, support marine law enforcement, and provide timely emergency rescue. After the satellite is in orbit, it will carry out on-orbit interstellar laser communication, interstellar telemetry telecontrol and other tests to verify the key technologies of two-star cooperative remote sensing and instant remote sensing, and provide an important reference for future satellite space interconnection."
