At 18:50 on March 30, 2023, the Long March 2D carrier rocket successfully launched the first batch of 4 SAR satellites of "Aerospace Hongtu-1" (including Zhongyuan-1 Hebi-1, Hebi-2, and Hebi-3) at the Taiyuan Satellite Launch Center in the form of one rocket and four satellites. The satellite successfully entered the predetermined orbit, and the launch mission was a complete success. Emposat successfully completed the first batch of 4-satellite Telemetry, Tracking & Command (TT&C) tasks of the "Aerospace Hongtu Nuwa Constellation".
As the overall implementation unit of the first batch of satellite commercial TT&C data transmission designated by satellite users, Emposat combined the constellation configuration of "one main and three auxiliary" 4-satellite coplanar operation, giving full play to the advantages of self-built global ground station network resources, and jointly dispatched the ground station resources of many commercial companies in Xi'anhuanyu and Guokehualu in China to form a high-coverage and highly reliable ground station network system to ensure the successful enter and flight control of the first batch of 4 satellites of the "Aerospace Hongtu Nuwa Constellation".
After the rocket was launched, Emposat called the Hainan Station, Yunnan Station, and Southeast Asia Station to complete the target acquisition and tracking in time after the satellite was put into orbit and powered on. At 19:03:38, the 3 stations of Emposat used 4 channels to track 4 satellites respectively, which provided a reliable guarantee for the judgment of the target's orbit status; 30 minutes later, Emposat South America station successfully tracked 4 satellites, and the TT&C time of the entire pass was as long as 10 minutes, which provided strong support for the judgment of key events such as the deployment of satellite solar panels, the orientation to the ground, and remote control operations; in the early orbit segment, Emposat will also provide continuous TT&C services for 4 satellites.
It is reported that after the first batch of 4 SAR satellites of "Aerospace Hongtu-1" are put into orbit, they will form the "Nuwa" constellation with the 34 satellites launched later, and the maximum revisit interval of any point in the world will not exceed 12 hours. The ability to complete national land coverage within 15 days and global coverage within 40 days.
Up to now, Emposat has provided paid services for 221 satellites/rocktes. In the future, it will continue to provide long-term management services for the constellation.
