13 Jul 2023: Chinese State Owned Enterprise, China Aerospace Science and Industry Corporation Limited (CASIC), announced the official start to the construction of an ultra-low orbit satellite constellation. This follows a previous announcement in late March and added new details and schedule information.

– CASIC said the first satellite of the ultra-low orbit satellite constellation will be launched in December (previously they had announced September) 2023, carrying payloads such as an optical remote sensing camera, spaceborne intelligent processing equipment, and an atomic oxygen detector.

– An ultra-low orbit is an orbital altitude of less than 300 km. This complex, dynamic environment requires space operators to offset the effects of the rapid orbital decay, due to heightened atmospheric drag.

– Ultra-low orbits have potentially high value. With lower orbit altitudes, Earth observation can shift from remote sensing to near observation, which has lower costs, higher resolution and shorter transmission delays.

– The ultra-low orbit satellite constellation will achieve 0.5-meter spatial resolution and transmit spatial information to users within 15 minutes, according to Zhang Nan, chief designer of the constellation.

– The CASIC plans to complete the launch of a nine-satellite cluster in 2024, and complete an orbital network of 192 satellites by 2027.

– By 2030, CASIC expects 300 operational satellites, providing diversified and real-time remote sensing services, and realizing global 15-minute response capabilities.
