The launch lifted off at 3:25 a.m. Beijing Time. The payload comprised satellites 07-09 of the Yaogan-53 group and satellites 19-21 of the Yaogan-56 group, all of which reached their intended orbits successfully.
China described the satellites as serving multiple purposes. They are primarily used for scientific experiments, land and resources surveys, crop yield estimation, and disaster prevention and reduction. The simultaneous deployment of two separate satellite groups on one vehicle reflects a clustered launch approach, with six spacecraft reaching orbit in a single mission.
The 673rd Long March mission continues an established cadence of orbital deployments from Jiuquan. The Long March-4B, the vehicle used for this flight, carried the combined Yaogan-53 and Yaogan-56 payloads without incident, according to the launch account.
China stated the satellites support civil applications including resource surveys, agricultural yield estimation, and disaster response. No further operational details about the spacecraft were provided.
The next milestones in China’s remote sensing deployment were not specified in the launch announcement.
