“The 5-meter optical 02 satellite has been successfully launched, constructing a terrestrial satellite constellation for mid range services, significantly improving the comprehensive observation capability of the Earth with a wide range of quantitative measurements. In orbit testing shows that the satellite system, ground system, and application system are functioning normally and operating stably. The data quality meets multiple business requirements, and the quantitative application testing of hyperspectral and thermal infrared payloads has achieved good results.”
