The satellite was later tracked in a roughly 463-mile-high (745 kilometers) sun-synchronous orbit (SSO) by the U.S.Space Force's 18th Space Defense Squadron as part of its space domain awareness activities.

The satellite carries VDES and automatic identification system (AIS) payloads for maritime-related uses and was developed by CASIC-owned Aerospace Xingyun Technology Co., Ltd., as part of plans for its "Xingyun" constellation.

The Kuaizhou 11 rocket can carry 2,220 pounds (1000 kilograms) of payload to SSO or up to 3,300 pounds (1500 kg) to low Earth orbit, making it five times more powerful than the smallerKuaizhou 1A

The first Kuaizhou 11 launch took place in July 2020 butended in failure. Expace also suffered anexplosion during testing at the Jiuquan spaceport, which may have been a factor in the two-year grounding of the rocket.

The mission was China's 57th launch of 2022, most of which have been performed by China's main space contractor CASC, including a number ofmissions to the country's Tiangong space station.
