A health check on all 52 in-orbit satellites of the BeiDou Navigation Satellite System has been completed, according to the Xi'an Satellite Control Centre. The satellites met all key indicators, meaning the constellation can provide services without issue. The evaluation was conducted without interrupting the satellites' usual navigation services, and developers and users were invited to participate in the process.
In addition to the assessment, a tailor-made maintenance plan was drawn up for each satellite to ensure operational efficiency.

China's high-resolution multi-mode imaging satellite Gaofen Duomo (Multi-Mode) has been officially put into use. The civil optical remote-sensing satellite provides data with a resolution at the sub-meter level for the use in industries including surveying and mapping, natural resources, emergency management, agriculture, ecological environment, residential construction and forestry. The satellite was launched on 3 July 2020 from the Taiyuan Satellite Launch Centre in north China's Shanxi Province. The summary review of its in-orbit test was completed on 17 December 2021. The test results show that the satellite is in good condition, works well, and has the conditions for putting into use, said the CNSA. This is China's first civil space research project adopting the public-private partnership model. The government is responsible for the development, data reception and processing of satellite images.
