The 5m Optical Satellite 02 (ZY-1-02E) was successfully launched on December 26, 2021. Along with the previous model (ZY-1-02D), an operational constellation of mid-resolution satellites will be established, forming a large-scale, quantitative and comprehensive earth observation capability. During the in-orbit test, the Ministry of Natural Resources designed a total of 32 application test items, focusing on land resources, geology and minerals, surveying and mapping geographic information, ocean island monitoring and other fields. All application items and other key indicators were evaluated in accordance with the relevant standards for natural resource survey and monitoring and technical specifications. The result shows that the satellite system, ground system and application system have been operating stably, and maintaining good consistency between each satellite of the constellation. It meets the data quality requirements of main businesses in various industries, hyperspectral and thermal infrared payloads achieved good application results. This paper will introduce the data characteristics and application capabilities of the satellite, focusing on evaluation results of some specific applications, especially with hyperspectral and thermal infrared cameras. It is hoped that this paper can provide a reference for the further application of this satellite.
