The Tianqi 25-28 satellites lifted off on a Ceres-1S rocket from a mobile platform off the coast of eastern China’s Shandong province at 4.12pm local time towards their designed orbit 850km (528 miles) above Earth, the rocket company Galactic Energy announced shortly after the launch.

Once complete, the Tianqi constellation will comprise 38 small satellites to promote data connectivity through smart devices, and provide global coverage and near real-time data transmission services to government, industrial and individual users, according to its developer and operator Guodian Gaoke, a Beijing-based satellite company.

“The existing Tianqi satellites have been used in a variety of scenarios, such as emergency communications and rescue, environmental protection and monitoring, and the transport of hazardous chemicals,” Lu Qiang, chief executive of Guodian Gaoke, told Chinese media last year.

“In the future, we will expand our services to other fields, including outdoor emergency response and military applications,” he said.
